Williams is the SP the Cubs got from the Giants for Hawkins. He was a fairly big prospect with the Giants and succeeded at a very young age last year. However his dad was having health problems this year, which many think caused him to lose concentration and got him demoted and eventually traded. However he's pitched better since coming to Iowa and had a nice start on Monday in Milwaukee.
says that it looks like Rusch will be heading to a bullpen. Here's a quote in case you don't want to read the whole thing.
Glendon Rusch and Sergio Mitre will likely be switched from the rotation to the bullpen, which will strengthen the bullpen. Mitre was 2-3 with a 5.19 ERA in seven starts while Rusch was 5-3 with a 3.13 ERA in 21 games, including 10 starts. The other starter in the mix is Jerome Williams, who gave up two runs on three hits over seven innings in his first Cubs start against Milwaukee on Tuesday. How will Rothschild choose between Mitre or Williams for the bullpen?
"Part of it will be who is best suited for the bullpen" Rothschild said. "Right now, I think you're looking at Williams starting and Sergio going to the bullpen because he can get ground balls. We need somebody who can come into an inning and get us out of an inning. I think he's more suited to warm up quicker. Nothing's etched in stone. We'll see."
Rusch is prepared for the switch.
"I'm ready for it. I talked to Larry and Dusty about it," Rusch said. "I wasn't yelling or screaming or anything."
