CINCINNATI -- The Reds still have "TBA" listed for their starting pitchers on Saturday and Sunday at Pittsburgh. One of those assignments could go to Dontrelle Willis, who was scratched on Sunday and again on Monday because of back spasms. Travis Wood filled in for Willis on Monday with five scoreless innings against the Astros and could be in the mix also. The two could also work in a tandem start. "He says he feels better today," Reds manager Dusty Baker said of Willis. "We're going to keep everybody else on and it'll probably be Dontrelle and Wood or Wood and Dontrelle. It depends on how [Willis] feels and if he can get a bullpen or something in between."
