But there's truly only one role Bass wants -- to start games. He'll get that chance on Thursday when the Padres face the D-backs at Petco Park, as the 24-year-old right-hander steps into the starting rotation for injured pitcher Dustin Moseley.
"I'm excited to have the opportunity to start," Bass said Wednesday. "I want to run with it and show the organization what I can do."
The organization already has a pretty good idea. In those 29 appearances in the big leagues, Bass has a 1.72 ERA with 43 hits allowed in 52 1/3 innings. He's made two appearances in the bullpen this season and, after Moseley suffered a shoulder injury in his last start, was the natural pick for the rotation.
"I suspect that he can go 70 to 90 pitches," said Padres manager Bud Black. "His history as an amateur and a Minor League pitcher is of a starter. There's no mental anxiety for him to be starting a game."
After Thursday, Bass' next start on Tuesday will come in a familiar place -- Coors Field in Denver. That is where Bass made his Major League debut for the Padres on June 13 in a spot start. Bass allowed one earned run in five innings that day for his first Major League victory.
