South Bend's Charles Brewer became unavailable to pitch for Tuesday's Midwest League All-Star game. So the East turned to TinCaps pitcher Jerry Sullivan as the starter.
Sullivan has a 5-3 record with a 3.72 ERA.
"It's fantastic," Sullivan said. "Getting the home field for the all-star game and getting to be in it and then to start the game is great. I'm going to try to get the fans into it.
"I'm excited. We're home, being able to have the home fans behind you, it's going to be a great atmosphere. I'm looking forward to it."
Peoria's Trey McNutt will start for the West. McNutt is 6-0 with a league-low 1.51 ERA.
