Tjen edges tiebreak, pulls clear to beat Vidmanova in Guadalajara

Janice Tjen came through a tense opening set and then pulled away, beating Darja Vidmanova 7-6, 6-2 in the Round of 32 at the WTA 1000 event in Guadalajara. The Indonesian's serve settled the match: 10 aces against just two double faults, and a punishing 85.7 percent of points won behind her first delivery. Her first-serve landing rate was only 53 percent, but she backed it up by taking 61.3 percent of second-serve points. Vidmanova served solidly enough, winning 79.3 percent behind her first ball, yet found herself under constant pressure once the second set turned. It is a notable win on the big stage for Tjen.
