I agree that Melky should be placed on the DL. He isn't at 100% and its not like he's hitting well anyways. His OPS is .688 and he's hobbling all over the place. Plus with Reyes coming back, I know the Jays want to still keep Bautista batting second, with EE batting third and Lind batting cleanup. Reyes slides into the leadoff spot, which pushes Cabrera down in the lineup, to either 6th or 7th. I think its an option they explore.
As for the pen, its been a team strength and I wouldn't want to mess with it by sending Loup or Wagner down. McGowan has been really useless in the pen, though for sure a team claims him if the Jays try to send him back down.
I doubt they DFA Izturis since they are committed to him long term and he's been hitting better. Boni has been a huge disappointment, though I think he's out of options and I think the Blue Jays still like him because he has speed and since he was part of that big deal with the Marlins. Unless you can trade Boni for a prospect etc, the Jays won't lose him for nothing.
The two likely scenarios I see are:
1) Cabrera to the DL on Monday; Reyes activated
2) Kawasaki sent down; Reyes activated
