Yeah, I agree with Peavy, +125 in a match like that is the right side.
While Isner's size brings a big serve, its just exceptionally difficult to carry that 6'6 frame through grand slam tennis. I missed the first three sets of this match but as a Cilic backer the final two were some entertaining/gut wrenching tennis to watch . A few games into the 4th it was obvious if Cilic could get to a 5th it would be Cilic's match to lose but than in the 5th Isners serve was off the charts! and held him in the match. The guy was barely moving but his serve just won service game after service game and he started to feed off it. In the end I think we got a better matchup against Nadal
