Here are some of the most memorable trades made at the deadline involving the Mets and Yankees.
DATE: June 15, 1977
TRADE: The Mets trade Tom Seaver to the Cincinnati Reds for Pat Zachry, Steve Henderson, Doug Flynn and Dan Norman
OUTCOME: Dubbed "the Midnight Massacre," the Mets traded the greatest player in franchise history to Cincinnati and got mediocre value in return. Seaver reportedly demanded a trade because his wife was jealous of the wife of Nolan Ryan, a former Met pitcher who had gotten a large contract from the California Angels. After the trade, Seaver continued his greatness with the Reds, with whom he won 14 games in 20 starts in '77. "Tom Terrific" also pitched a no-hitter in 1978, a feat the Mets organization would not match until 2012.
DATE: July 15, 1983
TRADE: The Mets acquire Keith Hernandez from the St. Louis Cardinals for Neil Allen and Rick Ownbey
OUTCOME: When Hernandez butted heads with St. Louis manager Whitey Herzog, the Cardinals’ loss was the Mets’ gain. The 1979 MVP and multiple Golden Glove winner helped steer the Mets back to respectability and was a cornerstone of the 1986 championship team. Cardinals fans initially claimed the trade put a hex on the team (which lost World Series in 1985, '87 and 2004), but the curse ended in 2006 when they defeated the Mets in the NLCS and the Tigers in the World Series.
DATE: August 27, 1992
TRADE: The Mets trade David Cone to the Toronto Blue Jays in exchange for Jeff Kent and Ryan Thompson.
OUTCOME: Cone was one of the top young pitchers of the early '90s, and the Mets claimed they traded him because they had no chance to re-sign the free-agent-to-be. But the Mets had also reportedly tired of his name popping up in off-field scandals. After he was accused of sexual misconduct in the Mets' bullpen, the underachieving Amazin's, dubbed the “Worst Team Money Could Buy,” traded him to the Blue Jays. Cone went on to win the World Series that year. Kent had a great career -- but not with the Mets. His career blossomed after he was traded for Carlos Baerga in 1996. Thompson, a supposedly top prospect, never hit better than .251 in four seasons with the Mets.
DATE: July 28, 1995
TRADE: The Yankees acquire David Cone from Toronto for Jason Jarvis, Mike Gordon, and Marty Janzen
OUTCOME: After Cone was traded away from the Mets in 1992, he made stops in Toronto and Kansas City. He never found a home until he came back to New York. In Cone’s first year he helped lead the Yankees to their first playoff appearance since 1981. In his second year he made only 11 starts as he had surgery to remove an aneurysm. Cone would eventually make his mark on Yankee fans, winning 64 games in six years and making two All-Star appearances. He threw a perfect game on Yogi Berra Day at Yankee Stadium in 1999 and, more importantly, Cone became a key clubhouse guy during the Joe Torre era.
DATE: July 31, 1996
TRADE: The Yankees acquire Cecil Fielder from Detroit for Ruben Sierra and Matt Drews.
OUTCOME: This trade helped the Yankees in two major ways: First, it helped clear the clubhouse of Sierra's attitude, which had soured after he claimed Joe Torre reneged on a promise to give him more playing time. Second, the addition of Fielder bolstered a Yankees team that was looking to make a serious postseason run. The hefty slugger found himself as the primary first baseman during the 1996 postseason and he didn’t disappoint. He hit .364 in the ALDS and .391 in the World Series as the Yankees won their first championship since 1978.
DATE: June 28, 2000
TRADE: The Yankees acquire David Justice from the Indians in exchange for Jake Westbrook, Zach Day and Ricky Ledee
OUTCOME: Yankees GM Brian Cashman pulled a rabbit out of his hat for this one, landing one of the better power hitters in the American League for a package of young players who never lived up to expectations. In 78 regular season games, Justice hit .305 with 20 homers and 60 RBIs. But his best moments came in October, when he was named the ALCS MVP after his three-run homer in Game 6 clinched the series against Seattle. The Yankees then defeated the Mets in the World Series for their third straight title and fourth in five years.
DATE: July 5, 2002
TRADE: Yankees acquire Jeff Weaver from the A's for Ted Lilly, Jason Arnold and John-Ford Griffin as part of a three-way trade involving the Detroit Tigers.
OUTCOME: This was one deal Brian Cashman would probably like to forget about. It seemed like a good idea at the time; Weaver was an up-and-coming arm with a hard fastball, but he turned out to be a disaster in New York. He appeared in 47 games and had an ERA over 5.00. The low point came in Game 3 of the 2003 World Series when he surrendered a 12th-inning, walkoff home run to Florida's Alex Gonzalez. Lilly went on to be one of the better lefties in the National League, winning 15 or more games from 2006-08 for the Cubs.
DATE: July 31, 2002
TRADE: Mets acquire Steve Reed and Jason Middlebrook from San Diego in exchange for Bobby Jones, minor league Josh Reynolds and minor league Jason Bay
OUTCOME: You probably missed this trade when it happened and it’s safe to assume most Met fans didn’t even know who Jason Bay was back in 2002. But when the Mets gave him up for solid righty reliever Steve Reed, they lost out on the early years of an All-Star career. Bay averaged 26 home runs and 87 RBIs in seven seasons with the Padres, Pirates and Red Sox before the Mets signed Bay to a fat four-year deal worth $66 million.
DATE: July 31, 2003
TRADE: Yankees acquire Aaron Boone from the Reds for Brandon Claussen, LHP Charlie Manning and cash
OUTCOME: 2003 ALCS, Game 7. That’s all that needs to be said. Boone made up for months of disappointing production by homering off Tim Wakefield to put the Yankees in the World Series. And, if it wasn’t for Boone tearing a knee ligament in a game of pick-up basketball in the 2004 offseason, the Yankees probably never would have gotten Alex Rodriguez, who was acquired to fill the third base void left by Boone. So there’s another thing you can thank Boone for.
DATE: July 30, 2004
TRADE: Mets trade Scott Kazmir and Jose Diaz to the Tampa Bay Devil Rays for Bartolome Fortunato and Victor Zambrano
OUTCOME: How bad was this trade? Met fans knew it was dumb then, and it's still dumb today. Zambrano was a pitcher with decent stuff and major control problems who led the American League in walks and hit batsmen in 2003. Kazmir was a prized lefthanded pitching prospect, deified by Mets fans who had endured more than a dozen years without a homegrown staff ace. Yet when pitching coach Rick Peterson claimed he could fix Zambrano's problems "in 10 minutes," GM Jim Duquette jumped at the chance to acquire him. Zambrano made 35 starts for the Mets from 2004-2006, going 10-14 and aggravating fans with his Oliver Perez-like command. Before recent injuries, Kazmir was a staff ace for Tampa Bay.
DATE: July 30, 2004
TRADE: Mets acquire Kris Benson and Jeff Keppinger from Pittsburgh in exchange for Ty Wigginton, Jose Bautista and Matt Peterson
OUTCOME: The second of two unarguably boneheaded moves made by GM Jim Duquette at the 2004 deadline. Benson managed just 14 wins in 39 starts for the Mets from 2004-2005. Unfortunately, his wife, Anna, made more headlines than he did. (She memorably appeared at a Mets Christmas party for school kids in a too-sexy Mrs. Claus outfit). Wigginton, criticized for his lack for raw talent, has fashioned a good MLB career with Baltimore. And Bautista has been lighting it up in Toronto, leading the majors in home runs in 2010. Benson, meanwhile, is toiling in the minors for Arizona. And yes, he’s still married to Anna.
DATE: July 30, 2004
TRADE: The Yankees trade pitcher Jose Contreras and cash to the Chicago White Sox for pitcher Esteban Loaiza.
OUTCOME: The Yankees' primary goal was to get rid of Contreras, who was a flop in New York and was signed to a four-year deal worth $32 million. The Yankees were happy to ship him to Chicago, where he ended up being a key component of their 2005 World Series team. Unfortunately, as the saying goes, "garbage in, garbage out." In exchange for their unwanted pitcher, the Yankees had to take back Loaiza, who made 10 appearances and finished his Yankees career with an 8.50 ERA.
DATE: July 30, 2006
TRADE: Yankees acquired Bobby Abreu and Cory Lidle from the Philadelphia Phillies for C.J. Henry, Matt Smith, Jesus Sanchez and Carlos Monasterios.
OUTCOME: The Yankees added some punch to their lineup with the disciplined run-producer Abreu, who fit in nicely in his two-and-a-half years here. He gave the Yankees stability in right field, something they had not had since the retirement of Paul O’Neill. Abreu finished his Yankee career with a .295 average, 43 homers, and 243 RBIs. Lidle, added for rotation depth, died tragically in a plane crash just days after the season ended. Of the prospects they gave up in the trade, only Monasterios has reached the majors, where he is a starter/long reliever for the Dodgers.
DATE: July 31, 2006
TRADE: Mets acquire Roberto Hernandez and Oliver Perez from the Pittsburgh Pirates in exchange for Xavier Nady
OUTCOME: It all started with a car accident in Miami. Mets setup man Duaner Sanchez was injured, lost for the season, so Omar Minaya tried to boost his bullpen. He acquired veteran reliever Roberto Hernandez. In giving up power-hitting rightfielder Xavier Nady, Minaya was savvy enough to get back lefthander Oliver Perez, a pitcher with control problems but major potential. Although Hernandez didn't help much in the 2006 postseason, Perez pitched well for the injury-riddled Mets and looked like a steal when he won 15 games in 2007. But since then, he has been nothing but trouble. Nady has struggled with injuries, but you can find more than a few Met fans who would probably take him over Perez, especially after what has transpired in 2010.
DATE: July 26, 2008
TRADE: Yankees acquire Xavier Nady and Damaso Marte from the Pittsburgh Pirates in exchange for Jeff Karstens, Daniel McCutchen, Ross Ohlendorf and Jose Tabata.
OUTCOME: When this trade was made, most fans thought the Yankees were getting only a solid outfielder in Nady. For a while, it seemed that way. Nady batted .268 with 12 homers and 40 RBIs in the remainder of the 2008 season. Marte, a lefty specialist, had a nightmare beginning to his Yankees career, pitching only 18.1 innings with an ERA over five. Both players sat out most of 2009 with injuries. With Nady set to become a free agent after 2009, the trade looked like a dud -- until Marte became a stealth weapon out of the bullpen in the 2009 postseason. Marte neutralized opposing lefties and especially excelled in the World Series against the Phillies' Ryan Howard and Chase Utley. Marte struck out both stars in Game 6 as the Yankees clinched their 27th title.
DATE: July 12, 2011
TRADE: Mets trade Francisco Rodriguez to the Milwaukee Brewers for Danny Herrera and Adrian Rosario
OUTCOME: The Francisco Rodriguez trade was the first brick laid -- or removed -- during the Mets' extensive four-year rebuilding process under general manager Sandy Alderson. When the trade was announced a half hour after the All-Star Game, "K-Rod" was in the middle of a solid season, with 23 saves as the Mets' closer to accompany a 3.16 ERA and his usual unsightly 1.406 WHIP. Rodriguez was famous during his days in Queens for his nightly tightrope acts. In save situations, he would often put multiple runners on base before securing the win. So, while the move heralded an era of painful mediocrity, many Mets fans were likely happy to reduce their ulcer medication. Strategically, the move was a salary dump for the Mets. In return, the Mets received Danny Herrera and Adrian Rosario from the Brewers. Rosario never saw action at Double-A Binghamton and Herrera only appeared in 16 games for the big-league club.
DATE: July 22, 2011
TRADE: Mets claim Mike Baxter off waivers from the San Diego Padres
OUTCOME: Mike Baxter, a native of Queens, spent three years as a serviceable fifth outfielder for the Mets, but on June 1, 2012, he was thrust into the center of New York legend, busted shoulder and all. In one of the many storylines of Johan Santana's no-hitter, Baxter found himself manning leftfield when St. Louis Cardinals catcher Yadier Molina sent a rocket over his head. Baxter stumbled on the warning track, caught the ball and went shoulder first into the outfield wall. He suffered a displacement of his right collarbone and fractured rib cartilage which would take roughly six weeks to heal -- the price of history. Grabbing Baxter near the 2011 trade deadline may not have sent the Mets hurtling into the postseason, but without his contribution that one night in Flushing,the Mets might still be waiting for one of the franchise's most iconic moments.
DATE: July 28, 2011
TRADE: Mets trade Carlos Beltran to the San Francisco Giants for Zach Wheeler
OUTCOME:Carlos Beltran spent seven years at the center of the New York Mets. In 2006, he enjoyed an MVP-caliber season and continued to play effectively as a middle of the order bat into the late 2000s despite many knee and other leg injuries. As the Mets faded into irrelevance after 2010, Beltran's bat became a valuable trade chip. In 2011, he was traded to the Giants after slugging 15 HRs and 66 RBIs with a .904 OPS by the end of July. In return, the Mets received Zach Wheeler, a raw blue-chip prospect and former sixth overall pick that had yet to put together his tools in the minor leagues. Wheeler eventually made it to the big leagues, compiling an 18-16 record, 3.50 ERA and 271 strikeouts in 285 1/3 innings from 2013-2014. Tommy John surgery forced Wheeler to sit out the 2015 season and much of 2016. Meanwhile, Carlos Beltran has continued to produce into his late 30s, including three All-Star appearances, one in 2016 with the Yankees.
DATE: July 31, 2015
TRADE: Mets trade Michael Fulmer and Luis Cessa to the Detroit Tigers for Yoenis Cespedes
OUTCOME: The Yoenis Cespedes trade capped off one of the most dramatic five days in Mets history. In a week that included a botched trade for Carlos Gomez, Wilmer Flores crying, a six-run blown lead to the Padres, a Flores walk-off home run and a sweep of the first place Nationals, the Mets traded for the Tigers slugger mere hours before the trade deadline. The move, designed to bolster the Mets' punchless bats, paid immediate dividends. The Mets' offense transformed into one of the most potent units in MLB while Cespedes slashed .287/.337.604 with 17 home runs in 57 games through the end of the season. After winning the NL pennant, Cespedes signed a three-year, $75-million deal with the Mets. In 2016, Cespedes has continued to provide consistent offense, slugging 21 home runs with a .302 batting average through the All-Star break. The trade was remarkably a win-win for both parties. Michael Fulmer, a former supplementary-round draft pick by the Mets, has exploded onto the scene in 2016 for the Tigers. Through 13 starts, Fulmer pitched to a 9-2 record, 2.11 ERA and 72 strikeouts while also setting the record for the most consecutive shutout innings (33 1/3) by a Detroit rookie pitcher.
DATE: July 25, 2016
TRADE: Yankees trade Aroldis Chapman to the Chicago Cubs for Gleyber Torres, Adam Warren, Billy McKinney and Rashad Crawford
OUTCOME: The Yankees acquired the flamethrower Aroldis Chapman from the Cincinnati Reds in the offseason to be the centerpiece of a three-headed monster in the back of the bullpen that included Andrew Miller and Dellin Betances. After serving a 30-game suspension for violating the MLB's domestic violence policy to start the 2016 season, Chapman performed as advertised. In 31 appearances, he put together a 3-0 record with a 2.01 ERA and 20 saves. But when the offense and rest of the pitching staff did not perform and the Yankees became sellers at the trade deadline, Chapman was the first piece to go. With the Cubs desperate for bullpen help, New York received an uncharacteristically large haul for a reliever. The biggest chip was 19-year-old shortstop Gleyber Torres. Torres was ranked the 26th best prospect by MLB.com heading into the trade and had compiled nine HRs, 47 RBIs and a .275 average with Single-A Myrtle Beach.
DATE: July 31, 2016
TRADE: Yankees trade Andrew Miller to the Cleveland Indians for Clint Frazier, Justus Sheffield, Ben Heller and J.P. Feyereisen
OUTCOME: Andrew Miller was the second piece to go during the Yankees' 2016 fire sale. As a member of New York's shutdown bullpen, Miller posted a 6-1 record and 1.39 ERA in 44 appearances. Like Chapman, Miller brought a large haul of prospects back to the Bronx. The headliner was 21-year-old outfielder Clint Frazier, who was ranked the 24th best overall prospect and sixth-best outfield prospect by MLB.com. At the time of the trade, Frazier had compiled 13 home runs, 48 RBIs, 13 stolen bases and a .273 AVG in 94 games split between Double-A Akron and Triple-A Colombus (five games).
DATE: August 1, 2016
TRADE: Mets trade Dilson Herrera and Max Wotell to Cincinnati Reds for Jay Bruce.
OUTCOME: A year after making a last-second trade on deadline day that propelled them to a strong finish to the season that culminated in their first World Series appearance since 2000, the Mets again made a move in the 11th hour of the trade deadline. Sitting 2.5 games out of the second National League wild card spot, they traded two prospects to the Reds in exchange for the league leader in RBI's in Jay Bruce, marking the first time the RBI leader is traded in the middle of a season in MLB history.
DATE: August 1, 2016
TRADE: Yankees trade Carlos Beltran to Texas Rangers for Dillon Tate, Erik Swanson and Nick Green.
OUTCOME: The final of many trades made by the Yankees as the move towards a rebuild, veteran rightfielder Carlos Beltran was dealt to the Rangers in exchange for three right-handed pitching prospects. Beltran hit .304 with a .344 on-base percentage, 22 home runs and 64 RBIs in 99 games with the Yankees before being traded. He was the team leader in average, home runs, RBIs, hits (109) and OPS (.890) and was tied for the team lead with 21 doubles.
