Just put $500 on this at Bet365. Seems great value to me, I see a 3 set game and if Fed does win in 2 sets I think it will be something like 7-6 6-4. Could have got +4 at +100 but I pushed with Fed -3 today so going for the win here.
I watched the entire Fed-Isner game today and Fed was sluggish. He wasn't even attempting to get to some of Isners drop shots and is either fatigued or is doing the bare minimum to get to the final. Either way suits me fine.
I think Delpo has the serve and the game to cause Fed some problems. I'm pretty sure Fed will win in the end but not much value in -500.
