ANAHEIM -- Rosters officially expand on Monday, which means anybody on the 40-man roster can be activated for the regular season's final month. The Angels are off that day but will have a new crop of players when they arrive in Houston to begin a 10-game, four-city road trip on Tuesday.
Here's a look at what the Angels could gain for September callups:
Fresh bullpen arms: That will be the biggest key for a bullpen that easily leads the Majors in innings since the All-Star break. Hard-throwing right-handers Michael Kohn and Cam Bedrosian are expected to be called up, as is veteran sidearmer Vinnie Pestano.
Third catcher: Every team calls up a third catcher in September, and for the Angels, that guy figures to be John Buck, the 11-year veteran who was signed to a Minor League deal on July 21. Buck has hit .292/.372/.416 in the Pacific Coast League. His presence could free up some time at designated hitter for Chris Iannetta. The Angels cleared up a 40-man spot for Buck when they outrighted reliever Dane De La Rosa on Friday.
Speed and power off the bench: Left-handed-hitting outfielders Tony Campana and J.B. Shuck can give Scioscia a couple of options for pinch-running late in games. Right-handed-hitting first baseman C.J. Cron and left-handed-hitting outfielder Brennan Boesch can provide some thump and could get some starts at DH. The Angels will probably also recall left-handed-hitting first baseman Efren Navarro, who was sent down on Saturday.
Length: Triple-A starters Wade LeBlanc, Randy Wolf and Drew Rucinski can be called up to give the Angels some innings out of the bullpen or be candidates to start on the days Garrett Richards' rotation spot comes up. LeBlanc and Wolf are lefties, but the Angels would have to create space on the 40-man roster to activate them. Rucinski, a right-hander, is already on the 40-man.
