Scott Mathieson will get his first look at a National League opponent when the Phillies take on the Padres on Wednesday night at Citizens Bank Park.
The rookie is 0-2 with a 6.75 ERA in three Interleague appearances, suffering losses in both of his starts. Mathieson, who was called up from Double-A Reading, will be making his first home start since his debut against Boston.
The Phillies started the second half of the 162-game schedule with a win Tuesday, but with a 10 1/2-game deficit in the NL East and seven teams to pass for the NL Wild Card, there is a lot of work to be done.
"It all depends on pitching and catching the ball," manager Charlie Manuel said. "This is the time of the season that our hitting should pick up."
Philadelphia batters will try to pick it up against San Diego right-hander Jake Peavy, who is a far cry from the pitcher who led the National League in strikeouts last season.
The 25-year-old has battled through shoulder tendinitis, going 1-5 in his last eight starts. In his last two outings -- both no-decisions -- he has shown signs of improvement, avoiding the big inning, which had been his downfall.
The Phils are going for their first three-game winning streak since a four-game sweep in Arizona on June 4-7.
SD: RHP Jake Peavy (4-8, 4.50 ERA)
He has struck out 109 and walked 23 this season.
PHI: RHP Scott Mathieson (0-2, 6.75 ERA)
He allowed five runs to Baltimore in 2 2/3 innings in his last start.
Player to watch
Bobby Abreu, shooting for the Final Vote spot on the NL All-Star team for the second time in three years, is 3-for-7 in his career against Peavy.
