The Diamondbacks have called up only four players as rosters expand on September 1st - 1B/LF Brandon Allen, 2B/SS Tony Abreu, RHP Carlos Rosa, and RHP Leo Rosales.  Of the four, Allen is the only one likely to get a real chance to play.  He has been playing LF extensively for AAA Reno over the last month, and should get a chance to start some games in LF in the Majors. Allen could also see time at 1B down the stretch, especially if Adam LaRoche continues to have problems with a slight knee injury.  Here are the stats for these players in 2010: Brandon Allen: .261/.405/.528, 25 HR, 86 RBI, 72R, 83BB, 95K Tony Abreu (AAA): .351/.386/.511, 2 HR, 21 RBI, 17R, 4 BB, 21K Tony Abreu (Majors): .237/.255/.298, 0 HR, 7 RBI, 12R, 4 BB, 29K Carlos Rosa (AAA): 0-0, 1.63 ERA, 1.23 WHIP, 27.2 IP, 14BB, 31K Carlos Rosa (Majors): 0-2, 6.75 ERA, 1.88 WHIP, 13.1 IP, 9BB, 8K Leo Rosales (AAA): 0-0, 5.06 ERA, 1.50 WHIP, 5.1 IP, 3 BB, 4K Leo Rosales (Majors): 2-0, 8.10 ERA, 2.10 WHIP, 10.0 IP, 6BB, 9K It is a little surprising that the Diamondbacks did not call up any starting pitchers for the last month of the season. Rodrigo Lopez has pitched very poorly in August (7.71 ERA, 1.78 WHIP in 30.1 IP), and AAA starters like Zack Kroenke (3.51 ERA), Matt Torra (4.45 ERA) or Kevin Mulvey (4.75 ERA) might be worth a look.  Also, there had been some talk about limiting the innings thrown by young starters Daniel Hudson (152 IP), Barry Enright (160 IP), and Ian Kennedy (165 IP).  But Manager Kirk Gibson has said that he prefers to stick with his regular lineup and rotation down the stretch, since the Diamondbacks will be playing teams that are involved in the pennant chase. Unfortunately, the  rest of the AAA rotation has also been pitching poorly, so the team felt there was not much point in calling up Bryan Augenstein (6.51 ERA), Cesar Valdez (5.98 ERA), or Wes Roemer (7.03 ERA).  Pitcher Brandon Webb also was not added to the roster yet. Although Webb threw off a mound to batters earlier this week, the team feels he is still not ready to join the active roster.
