Dalibor Svrcina vs Adam Walton — R32 — Los Cabos Open

Svrcina's serve was the problem, then the solution. Nine double faults came in the opening set, where he won 52 percent of first-serve points and Adam Walton banked a 7-2 tiebreak. Then the leak stopped. Dalibor Svrcina threw three more double faults from there, won 64 and 65 percent of first-serve points across the final two sets, took the second-set tiebreak 7-2 and broke in game 4 of the third for 3-1. Walton converted at the better break-point clip, 6 of 11 to Svrcina's 7 of 16, yet finished behind on breaks and total points, 121-120. The ATP No. 115 closed on his second match point, 2 hours, 54 minutes in, for a first win since Indian Wells in March that snaps a four-match slide.
