In 13 days, the Orioles will presumably stop their roster juggling. On Sept. 1, theyll be able to increase their roster from 25 to 40 players.With the Orioles in contention for the playoffs, manager Buck Showalter said that the team is likely to add some different players than they might if they werent.The team has four players on the 15-day disabled list. Jim Thome (neck spasms), Troy Patton (sprained right ankle), Wilson Betemit (right wrist) and Ryan Flaherty (bacterial infection.)Flaherty should be back soon, Betemit and Patton hope to be back late this month. Thomes future is uncertain. He cant swing a bat for 30 days, but once hes allowed to, he could return quickly if hes healthy.Some position players currently at Norfolk who could be called up on Sept. 1 include first baseman Joe Mahoney, who has had two brief stays with the Orioles, catcher Luis Exposito, infielder Steve Tolleson, outfielders Endy Chavez and L.J Hoes. The addition of Exposito could give the Orioles a third catcher. Ronny Paulino, who was Matt Wieters backup for most of the first half of the season, is not on the 40-man roster.Chavez, who was hampered by injuries and poor performance in his four months with the Orioles, is just 1-for-14 since joining Norfolk. Hoes is not on the 40-man roster, but hes batting .321.Xavier Avery, who impressed in his stays with the team earlier in the season, hasnt hit well in his return to Triple-A. He may not merit a September recall.Pitchers who could be added are Brian Matusz, Greg Burke, Zach Phillips and Jason Berken. Matusz is currently in the bullpen, and both he and Phillips are left-handers. Burke has pitched very well since his promotion in late June. Jake Arrieta and Dana Eveland could be brought up, too. Burke, Eveland and Phillips are not on the 40-man roster. Dylan Bundy, who is scheduled to pitch for Bowie on Monday, is also a possibility.
