Utility man Geoff Blum and left-hander Alberto Castillo, on the disabled list with a fractured right pinkie and left shoulder tendinitis, respectively, have played well in recent rehab games and therefore will rejoin the team when it begins a three-game series in San Francisco on Friday. Right-handed relievers Ryan Cook and Sam Demel, each of whom have spent time in the big league bullpen this season, are also on their way.
That is all for the moment. The D-backs' top two minor league affiliates, Triple-A Reno and Double-A Mobile, have made the postseason, and therefore do not want their rosters completely depleted of players. At the same time, the D-backs will do what is best for the major league team.
"You have to be sensitive to that, yet we don't want to be the team that is short if we go into a 20-inning game. You're talking about the bullpen," Gibson said.
"I was never one to have too many. I think it can kind of mess with the chemistry of the club," said D-backs general manager Kevin Towers, whose teams often were in contention while he was in San Diego. "It's not going to be 40. It's probably not going to be 35. It's going to be less than that. You usually add an extra catcher, usually a couple of extra arms. Maybe a defender, a bat."
The D-backs have a stable of quality arms at Mobile, including right-handers Trevor Bauer and Jarrod Parker and left-handers Tyler Skaggs and Patrick Corbin, but Towers would not say whether any of them will move moved to the majors. Bauer, the third player taken in the 2011 draft, is on the 40-man roster after signing a major league contract July 25. Parker, Skaggs, and Corbin are not, although Parker must be protected this winter after being a first-round draft choice in 2007.
"I don't want to get into names," Towers said. "There are a lot of guys at Double-A and Triple-A that we will probably discuss."
The D-backs have 39 players on their roster. Konrad Schmidt, who spent September with the D-backs last year, is the only other catcher on the 40-man roster.
