The expansions of MLB rosters during September - a subject of recent debate - provide opportunity for talented prospects to showcase their worth. We take a look back at some of the more memorable September call-ups, defined here as players that made their major league debuts during the month.
Daric Barton reached base safely in all 18 games that followed his debut for the Oakland A's during September 2007. He earned the starting first baseman job the next spring but later lost it and ended up back in the minor leagues.
Before the World Series rings, All-Star Gamesfried chicken, Beckett proved his worth in September 2001 when he allowed just four earned runs and registered 24 strikeouts in as many innings for the Florida Marlins.
Tim Belcher, who would become a 14-year MLB veteran, impressed once the Dodgers called him up in September 1987. The right-hander had a 2.38 ERA through 34 innings and finished third the following season in Rookie of the Year voting.
Gary Carter's Hall of Fame career started with a productive September 1974 call-up with the Montreal Expos. His 11-for-27month set a precedent that led to second place in the Rookie of the Year balloting the next year.
The Rays filled a hole in their starting rotation by calling up Davis in September 2009. Davis started six games and kept his ERA below 4.00.
An outfielder with the words "potential" but also "injury-risk" attached to him throughout his career, Drew lived up to expectations and created better ones during his September 1998 stint. In just 14 games, Drew belted five home runs and drove in 13 runs for the Cardinals.
During an otherwise irrelevant September 2010 for the Mets, Dillon Gee debuted and started five games, posting a 2.18 ERA through 33 innings.
Fred Lynn won the AL Rookie of the Year, MVP and Gold Glove Award in 1975. He was also an All-Star that season, all foreshadowed by his September of 1974 when he went 18-for-43 with 10 RBIs.
The Rays promoted left-hander Matt Moore on Sept. 12, 2011. Less than three weeks later, he started his second career game, this time in Game 1 of the ALDS against the Texas Rangers, and tossed seven scoreless innings.
A rare highlight for the Minnesota Twins in September 2011, Parmalee slugged four home runs, drove in 14 runs and batted .355 in 76 at-bats. Despite Parmelee's initial success, he has struggled to keep his average above .200in 2012.
Although Price debuted on Sept. 14, 2008 in a game against the Yankees, he earned a post-season win and two post-season saves before he notched his first regular season career victory.
Rodriguez jumped onto the scene for the Angels' World Series run during 2002 after he made his debut on Sept. 18. Despite only pitching in five games for the Angels, the team placed him on its postseason roster. “K-Rod” helped pitch the Angels past the Yankees and Giants by earning victories in both series.
Fernando Valenzuela's 17.2 scoreless innings after his September call-up in 1980 foreshadowed a rookie season in 1981 that saw him capture Most Valuable Player and Rookie of the Year honors, and a World Series title with the Dodgers.
