Orioles manager Buck Showalter said after tonight's game that a decision on whose rotation spot Brian Matusz would take would be made "down the road." About an hour later, the answer became pretty clear. After tonight's game, the Orioles optioned Brad Bergesen, who allowed three runs (two earned) in 5 2/3 innings in a 4-2 loss to the Oakland Athletics, to Triple-A Norfolk. Bergesen was 1-6 with a 5.36 ERA in 10 games (nine starts) for the Orioles. Double-A Bowie reliever Pedro Viola is expected to be recalled before Sunday's series finale, but his big league stay will likely be a short one with Matusz in line to be activated from the disabled list Wednesday and start that afternoon against the Seattle Mariners.
