Manager Walt Weiss said he believes Belisle (1-2, 4.22 ERA) is in a good place.
"These guys are not going to be perfect every time out, but I think Matt's throwing the ball well, and he threw the ball well last night," Weiss said. "He threw a slider in the middle of the plate to one of the best hitters in baseball. I don't think it's a matter of Matt slumping."
