"Manager Dusty Baker revealed after Saturday's game that right-hander Edinson Volquez will start the Reds' playoff opener next week.

Right-hander Aaron Harang, bumped to the bullpen earlier this month, will start the regular season finale against Milwaukee Sunday in place of Volquez.

Harang's last start was Sept. 6 and he since has made only two relief appearances, most recently Sept. 22.

Baker would not reveal any of his other playoff starters, saying he probably will announce that Sunday. Speculation is that Harang will not be on the postseason roster, but Baker will not comment on that.

Volquez had Tommy John elbow surgery on Aug. 3, 2009. He made his 2010 season debut on July 17, and for the year is 4-3 with a 4.31 ERA. Volquez was an All-Star in 2008.

"He's coming on pretty strong and he's been especially good against lefties," Baker said. And they've got a lot of lefties."

Baker was talking about Philadelphia, the Reds' probable playoff foe. Numerous scenarios could also include the Reds facing the eventual NL West champion, San Diego or San Francisco."
