At Miami, James Blake had high praise for 18-year-old Serbian wild card Filip Krajinovic, whom he beat 6-7(6), 6-4, 6-4 in the first round.

"From what I saw tonight he's got a lot of talent, moves great, very solid and a weapon in the backhand," said Blake. "His serve needs to improve, get a little bigger, especially a second serve. He needs to do a few more things and get a little bigger and stronger for sure to compete every week on this tour, but I'd take that ability at 18 years old over what I was working with at that age."—M.C.
