Sam Querrey (Orange County Breakers) prevailed in a #WTTFamily clash on Monday at Roland Garros, defeating Frances Tiafoe (Washington Kastles) 6-1, 6-2, 7-6(6).

Querrey saved all six break points he faced and fired 11 aces to lock up the first-round encounter in one hour and 50 minutes. He improved to 2-0 against Tiafoe, adding to a 2017 victory in Shanghai.

Seeded 12th at this year‘s event, Querrey snapped a three-match losing skid in the opening round at the Paris major. His best showing came in 2013, when he advanced to the third round, a result he can equal should he defeat local favorite Gilles Simon in his next match.

Top-ranked American John Isner (New York Empire) was also in action, taking on compatriot Noah Rubin. Isner led 6-3, 7-6(7) before rain halted play.

WTT rookie Naomi Osaka (Kastles) opened her tournament by advancing in straight sets. The 21st seed eliminated Sofia Kenin 6-2, 7-5, winning 56 percent of her return points in the 74-minute victory.

Osaka captured her first WTA title at the Premier Mandatory event in Indian Wells earlier this year, following a round of 16 effort at the Australian Open. The 20-year-old next faces Zarina Diyas in a first-time meeting.
