Marin Cilic pulls out sick

Djokovic needs extra set to go through

Marin Cilic, the 2014 U.S. Open champion and 2017 Wimbledon runner-up, pulled out of the grass-court Grand Slam tournament because of illness.

The All England Club announced Cilic's withdrawal on Monday and said he will be replaced in the draw by 123rdranked Nuno Borges of Portugal.

Borges lost during qualifying for Wimbledon. Now he will face Mackenzie McDonald of the United States in the first round of the main draw on Tuesday.

Cilic was coming off a semifinal run at the French Open earlier this month. That made him the fifth active man to complete a full set of semifinal appearances at all four major tournaments, joining Rafael Nadal, Novak Djokovic, Roger Federer and Andy Murray.

Hubert Hurkacz came into Wimbledon as a contender for the title. He'll leave after the first round.

The seventh-seeded Pole lost to Alejandro Davidovich Fokina of Spain 7-6 (4), 6-4, 5-7, 2-6, 76 (10-8) on No. 3 Court on the opening day of the tournament.

The 25-year-old Hurkacz beat Roger Federer a year ago on Centre Court en route to the semifinals. He then prepared for Wimbledon by beating topranked Daniil Medvedev in the final of the grass-court event in Halle, Germany.

Federer isn't in the field this year after a series of knee operations and Medvedev is missing the tournament because all players from Russia and Belarus are banned over the war in Ukraine.

Novak Djokovic needed one set more than expected to reach the second round at Wimbledon.

The top-seeded Serb, a six-time champion at the All England Club, beat Kwon Soon-woo 6-3, 3-6, 6-3, 6-4 on Centre Court.

Kwon played well with the roof closed on the main stadium, but Djokovic improved midway through the third set.

It was Djokovic's 80th victory at the All England Club, making him the first man or woman to have won at least that many matches at each of the four major tournaments.

Alison Riske became the first player to reach the second round at Wimbledon.

The 28th-seeded American beat Ylena In-Albon of Switzerland 6-2, 6-4 on Court 10.

Third-seeded Ons Jabeur advanced a short time later, completing her 6-1, 6-3 victory over Swedish qualifier Mirjam Bjorklund.

Jabeur reached the quarterfinals at the All England Club last year and won a grass-court title in Berlin heading into this year's tournament.

The first rain delay at Wimbledon came about 40 minutes into the opening day of the tournament.

A light rain began to fall at the All England Club at about 11:40 a.m. and play on 15 courts was suspended.

Centre Court and No. 1 Court at Wimbledon both have a retractable roof, but play doesn't start in those stadiums until later in the day.
