Re: Which USO win was more impressive/deserving? Delpo or Murray?
Del Potros was probably slightlyy more impressive due to it coming out of nowhere and beat both Nadal and Federer in one tournament. However Murray was battling history and the way he lost his two set lead and went on to just outplay Djokovic in that final set was very, very impressive. His ability to raise his level at that point after being 2 sets to 0 was amazing. Either way, I'd give Delpo the nod in that department.
In terms of deserving it more. Andy Murray wins that hands down. He lost four finals in a row, he'd been knocking on the slam winners door since 2008/2009 and it just didn't come together. But the guys worked so hard on getting more physically strong, and now mmore positive and mentally strong on court that he absolutely deserved it more.
