okay 2009 was a choke, but that was baby delpo ffs, and in 2012 everyone knows he was injured half way through that match
2009 wasn't a choke, his fitness was just absurdly low at the time. He absolutely dominated Federer in the first 3 sets - Fed didn't even get a break point in 3 sets - but Fed somehow eeked out the second set in a tiebreak and eventually outlasted Delpo. It was a bit like the AO semifinal this year (Murray vs Fed) in terms of ascendency, only with Murray remaining strong for 5 sets and Delpo running out of gas.
Shame, since he'd definitely have beaten Soderling in the final, was only a few points away from a RG title. But that match made him improve his fitness, which proved crucial at USO so it was all good.
