Blue Jays manager John Farrell indicated Wednesday that Dustin McGowan could replace Luis Perez in the starting rotation Sunday against the Orioles. Perez is still listed as the starter, but the Blue Jays are considering a change after he allowed eight runs over just 2 2/3 innings on Tuesday against the Red Sox. "There's discussion about that," said Farrell. "Right now, we're anticipating Luis going to start on Sunday. We may determine some time in the next couple of days that we may look to make a shift there and start Dustin in that spot." McGowan allowed three runs over four innings Tuesday in his first appearance in the big leagues since 2008, but was being groomed as a starter in the minors. He could hold some value in AL-only leagues down the stretch.
