I'd go with Morrow, and latos for sure. I don’t know much about Duensing, but he's a lower level pitcher so I'd hold back on him. Carpenter has been play extremely poorly and I would wait for him to get back on track. While, Latos has also been playing poorly, I have much more faith in playing him and hoping that it will be the game he bounces back, than I do in playing Carpenter. Morrow seems like no-brainer, as he has been pitching very solid ball, and the jays are hot right now.
