I think it was the tension of keeping away from Cotto that saw Yuri's knee go, along with the shots Cotto was landing. It must have been so demoralising to land your best shots in the fourth, finally use your speed properly and then have Cotto adjust so effectively in the next round. He just couldn't do anything, and he was getting hit. Keeping moving like that must be exhausting when you know that by stopping you're going to get the left fist of Miguel in the face.
Did it look like Cotto's balance and ability to throw combinations had been corrected? I mean has steward changed much?
without a doubt mate, he looked like a different fighter to me. he was putting combinations together fluently and not having to re-set his feet after a jab or a 1-2 that he has been guilty of recently. his footwork was a million times better as well
