British number one Johanna Konta reached the Wimbledon second round by beating Natalia Vikhlyantseva but made harder work of it than necessary. Konta, a semi-finalist last year, got the crucial break in the 11th game of the first set and was an early break up in the second before being pegged back in a 7-5 7-6 (9-7) win.
The 22nd seed needed her sixth match point to beat the Russian 21-year-old. Konta faces Slovak former world number four Dominika Cibulkova next.
Konta, whose dream run at the All England Club last year lifted her to a career-high fourth in the world, has struggled for form this year and has slipped to 24th in the rankings.
There have been some signs of recovery with the 27-year-old reaching the final of the grass-court event in Nottingham last month before she was knocked out of the Birmingham and Eastbourne events by top-10 players Petra Kvitova and Caroline Wozniacki respectively.
