Former finalist Milos Raonic is through to the third round of Wimbledon for the sixth year in a row.

Raonic beat Robin Haase 7-6 (1), 7-5, 7-6 (4) to set up a meeting with unseeded American Reilly Opelka, who upset Stan Wawrinka.

Raonic needed treatment on his left ankle and Achilles when trailing 5-4 in the third set but finished off the win by converting his first match point in the tiebreaker. The Canadian was broken only once in the match as Haase took a 6-5 lead in the first set, but Raonic broke right back. Raonic lost the 2016 final to Andy Murray.

Thomas Fabbiano of Italy also advanced, following up his upset win over Stefanos Tsitsipas by beating Ivo Karlovic 6-3, 6-7 (6), 6-3, 6-7 (4), 6-4. At 40, Karlovic became the oldest man since 1975 to win at Wimbledon by advancing to the second round. The Croatian finished with 38 aces but only forced one break point in the match, which he couldn’t convert.

Unseeded Reilly Opelka of the United States edged three-time major champion Stan Wawrinka 7-5, 3-6, 4-6, 6-4, 8-6 at Wimbledon to reach the third round of a Grand Slam tournament for the first time.

The 63rd-ranked Opelka earned the only service break of the fifth set in the last game, helped by four groundstroke errors from Wawrinka, who was seeded 22nd.

This was only the sixth Grand Slam match of the 21-year-old Opelka’s career. He defeated John Isner in the first round of the Australian Open in January.

The 6-foot-11 (2.11-meter) Opelka hit eight of his 23 aces in the last set, when he saved both break points he faced. In all, he fended off 10 of Wawrinka’s 12 break chances.

Wimbledon is the only major tournament Wawrinka hasn’t won.
