I agree that you have to manufacture runs, but we weren't banking on a homer. If he doesn't send Drew, then he makes it back to first. At worst, we have runner on 1st with 1 down. Then assuming Crisp gets that hit, you have 1st and 2nd with Papi at the plate. They can't put the shift on in that situation, giving Ortiz more of a chance to plate a run. Then Manny comes up...
Yeah, a lot of if's, but with the potential of things like that happening, you can't take risks like that. It was in too crucial of a situation to try making something happen.
