CINCINNATI -- Edward Mujica will be the latest Padres pitcher to showcase his stuff as a starting pitcher. After throwing a bullpen session on Wednesday, manager Bud Black announced Mujica would start on Saturday against the Brewers.

"We're going to see if we have a starting pitcher in the making," Black said. "All of us like the age, size, arm strength, his three pitches and good delivery. This could be something to try."

Mujica will replace starter Josh Geer, who will move to a long reliever role in the bullpen. Mujica is 2-4 with a 3.24 ERA in 46 games, and last started in 2004 in Class A.

Black said the Padres would likely limit Mujica to 45-65 pitches in his first start because of his lack of familiarity with the role. Mujica pitched three innings Monday against the Reds and gave up just one run.

"It's more of his style of pitching," Black said. "His secondary pitches are solid."

Mujica said he will work out of the stretch and the windup. He was converted from a starter to a closer in 2005, when he moved to Triple-A.
