Trainer Todd Pletcher said afterwards that Uncle Mo grabbed his left-front quarter, shearing off a piece of the hoof wall the size of a quarter while leaving the gate sharply in what appeared to be a clean break, but would not use the mishap as an excuse. Uncle Mo's immediate future, however, is uncertain.
"He grabbed a quarter leaving the gate," Pletcher said. "It didn't help but I'm not using that as an excuse. After that, he was kind of hounded early on. The fractions were reasonable. It was his first time going a mile and an eighth, first time over the Aqueduct surface. I was a little concerned turning for home at the three-sixteenths pole when he didn't really kick clear. I thought then that we were going to be in for a fight. You could see the last fifty to sixty yards he was tired.
"It goes without saying that if he wins by 10 today he goes [to Kentucky] with quite a bit different morning line than he is now. It doesn't mean we're not going to go, it doesn't mean we are going to go. We'll see how he comes out of it and make sure he's physically okay, that's a priority. It's totally up to Uncle Mo. My confidence hasn't changed in the horse. He's got a good win at Churchill and maybe this is what he needed to step forward four weeks from now."
