Two-time champion Serena Williams has opened her Wimbledon campaign with a 7-5, 6-3 win over Estonia’s Kaia Kanepi in the opening match on Court 1.

Williams, whose Wimbledon wins in 2002 and ‘03 are among her seven major titles, fended off five breakpoint chances in the first set Monday and converted on her only opportunity on set point when French Open quarterfinalist Kanepi double-faulted.

Williams, seeded sixth, broke Kanepi once in the second set and served out at love.
