OAKLAND, Calif. - Scott Kazmir is heading to his hometown Houston Astros and into the thick of a pennant race, and the Oakland Athletics are starting their summer sell-off.
The A's began their expected changes leading up to the July 31 trade deadline, sending the left-hander to the Astros for a pair of minor leaguers Thursday in what could be the first of many significant deals across the majors in the next week.
Oakland received sought-after catcher Jacob Nottingham and right-handed pitcher Daniel Mengden in the swap with its AL West rival -- and the Astros got a top-tier starter as they chase a playoff berth in the season's second half. Houston hasn't been to the playoffs since being swept in the 2005 World Series by the Chicago White Sox when the Astros were still in the National League.
Even with all the trade talk surrounding him, the news caught the 31-year-old Kazmir by surprise. He was scheduled to start Thursday against Toronto and woke up preparing to play at least one more game in green and gold.
Instead, Kazmir got a phone call from A's general manager Billy Beane and manager Bob Melvin informing he had been traded. He packed up his belongings in the A's clubhouse while getting hugs and handshakes from teammates.
"It felt like it just hit me at once. It's going to take some time to sink some stuff in," Kazmir said.
Kazmir is expected to join the Astros in Kansas City on Friday. He went 5-5 with a 2.38 ERA in 18 starts for Oakland.
Drew Pomeranz started in Kazmir's place against Toronto, and Oakland recalled right-hander Arnold Leon from Triple-A Nashville to take Kazmir's roster spot.
Nottingham and Mengden were at Class A Quad Cities to start the season before being promoted to the organization's higher A club in Lancaster of the California League. They will report to Class A Stockton.
While Kazmir has been reportedly on the move for weeks, Beane said he wasn't actively shopping the starting pitcher. But when the Astros included Nottingham in the deal, he said the trade "came together pretty quick."
It's the first of what could be many moves for Oakland before the non-waiver trade deadline. The A's, who made the playoffs the past three seasons, entered Thursday with a 44-52 record -- 11 games behind the division-leading Los Angeles Angels.
"We have to be realistic with where we are," Beane said. "The math doesn't necessarily work in our favor given the level of play we need just to get back in it."
Melvin said he didn't have a chance to address players before the game but didn't feel he needed to. He said they know roster turnover is part of the business.
"When you're here in Oakland, you understand that moves are made, whether it's offseason or in-season," Melvin said.
The A's acquired Kazmir as a free agent in December 2013 and he was 20-14 with a 3.12 ERA in 40 starts over parts of two seasons, including making the AL All-Star team last year.
Houston (53-43) began the day in second place in the AL West, two games behind the defending division champion Angels. The Astros were hosting Boston in a night game Thursday.
"Scott Kazmir is one of the best pitchers in the American League and strengthens our rotation," Houston general manager Jeff Luhnow said. "His addition gives the Astros a better chance of reaching and succeeding in the postseason. It has been a while since the Astros have been relevant late in the summer and winning now is a priority."
Kazmir said it's tough to leave the A's behind, but he's excited to help his hometown Astros make a playoff push.
Kazmir was an All-Star with Tampa Bay in 2006 and 2008. He was limited to one start in 2011 with the Angels before going on the disabled list with a lower back strain and being released.
He spent the 2012 season with independent Sugar Land -- just outside Houston -- before bouncing back to go 10-9 with a 4.04 ERA in 29 starts and 158 innings for Cleveland. He has continued to reinvent himself in Oakland and has returned to his status as one of baseball's most reliable arms.
"It's been crazy, to be honest with you," Kazmir said. "Playing independent ball and I'm thinking I would never be able to play professionally. And now I'm going back to my hometown and going to play for the Astros. It's a complete whirlwind, but I'm excited for the opportunity."
