When Alou was asked who his closer would be on the pre-game show, his response was "It's a good guess."
As for a starter becoming the closer, I really don't see that happening. Some of us speculated that Foppert might get a look if they didn't sign a closer in the offseason, but now he has a blister problem.
Here's a quote from Alou on converting a starter:
"This is more bleeding we have to stop," Alou said. "Last year we converted one of the starters and he saved our life. Right now, we don't have a guy like that who's been a closer."
Frankly, I don't know what they're going to do.
