Fed went from 6-3,6-2 with no break points and no double faults served in 55 minutes- clinical rapid performance to 6-3,7-5 serve broken on consecutive occasion and an extra 20 minutes spent out on the court.
Lucky it was Judy Murray he was facing and not a more clutch player or he would've paid the price.
Up until 6-3 5-2, it was a really solid performance from Federer, probably his best on clay this season. Then he mentally checked out before the match was over. Terrible to see. He's lucky he was facing Chokerson.
