TENNIS

MIAMI OPEN: Eight-time champion Serena Williams won her opening match at the event’s new site in Miami Gardens by beating Rebecca Peterson 6-3, 1-6, 6-1.

Williams played poorly for a stretch and was broken three times but steadied her game in the final set to pull away. She avoided a repeat of last year, when she was eliminated in her first match by Naomi Osaka.

The No. 1-ranked Osaka beat qualifier Yanina Wickmayer 6-0, 6-7 (3), 6-1. Osaka hit 14 aces and overcame a ragged stretch in the second set, when she became so frustrated she threw her racket.

Defending men’s champion John Isner hit 20 aces, lost only 11 points on his serve and beat qualifier Lorenzo Sonego 7-6 (2), 7-6 (7).

No. 5-seeded Kei Nishikori was upset by Dusan Lajovic 2-6, 6-2, 6-3. Lajovic improved to 3-14 against top-10 players.
