LONDON (AP) The Latest on Wimbledon (all times local):
Because of rain, play has been suspended for the day at Wimbledon on all courts except Centre Court.
Two-time major champion Svetlana Kuznetsova and former No. 1 Caroline Wozniacki have started their first-round match at Centre Court with the roof closed.
Play is still being delayed by rain on other courts.
Didn't take long for the first rain delay of Wimbledon this year.
Play has been halted on all courts Tuesday, Day 2 of the tournament, because of a shower.
The retractable roof is closed on Centre Court, the only arena at the All England Club where play can proceed when there is wet weather. Due there next is a match between two-time major champion Svetlana Kuznetsova and former No. 1 Caroline Wozniacki.
The first all-British men's match at Wimbledon in 15 years went as expected. Andy Murray was kept busy for 102 minutes by Liam Broady in winning 6-2, 6-3, 6-4.
Murray wasn't broken, and broke Broady, ranked 235, four times in their first meeting.
''It's hard playing someone you know, but I did OK,'' Murray said.
Fourth-seeded Stan Wawrinka was extended to a fourth set before subduing American teenager Taylor Fritz to reach the second round at Wimbledon.
Wawrinka, who had lost in the first round at the All England Club five times, passed the 18-year-old Fritz 7-6 (4), 6-1, 6-7 (2), 6-4 on Court 1.
The 65th-ranked Fritz, making his Wimbledon debut, was the youngest man in the draw.
Also advancing was Juan Martin del Potro, the big-hitting Argentine making his first appearance at a Grand Slam since the 2014 Australian Open after a series on surgeries on his left wrist.
Del Potro, the 2009 U.S. Open champion now ranked 165th, beat Stephane Robert of France 6-1, 7-5, 6-0.
Serena Williams began her Wimbledon title defense with a comfortable but tentative win over Swiss qualifier Amra Sadikovic, winning 6-2, 6-4 on Centre Court. Williams won the final point on a line call challenge.
The six-time champion barely served any better than the 148th-ranked Sadikovic, who was making her main draw debut in a Grand Slam at the age of 27.
Williams' serve was shaky, she was broken once, and hit more unforced errors. But in her first match since her loss in the French Open final to Garbine Muguruza, Williams advanced to a second-round meeting with fellow American Christina McHale.
Back on the same No. 2 Court where his Wimbledon campaign imploded last year, Nick Kyrgios behaved and beat Radek Stepanek 6-4, 6-3, 6-7 (9), 6-1 to open his latest run at the All England Club on Tuesday.
The match really got interesting only when Kyrgios tried to finish it in the third set. He was broken serving for the match at 5-4, and was 5-2 down in the tiebreaker before squandering two match points and losing it. Kyrgios was warned for an audible obscenity in the changeover, and took out his frustration on Stepanek by rolling through the fourth set.
Stepanek, trying at 37 to become the oldest man to win a Grand Slam match since Jimmy Connors at the 1992 U.S. Open, didn't serve well enough and was always under pressure.
Kyrgios was a Wimbledon quarterfinalist on debut in 2014, and departed in the fourth round last year in a loss which included a code violation for swearing and unsportsmanlike conduct against the umpire.
He's seeded to meet Andy Murray in the fourth round.
French seeds Richard Gasquet and Jo-Wilfried Tsonga moved into the second round of Wimbledon with straight-set wins.
No. 7 Gasquet swept past Britain's Aljaz Bedene 6-3, 6-4, 6-3, while No. 12 Tsonga got past Spain's Inigo Cervantes 6-4, 7-6 (5), 6-4.
Gasquet reached the Wimbledon semifinals last year, while Tsonga made it to the semis in 2011 and 2012.
Leave it to showman Nick Kyrgrios to pull off a shot like this.
The Australian hit a between-the-legs shot – a ''tweener' – from behind the baseline that sailed over Radek Stepanek's head at the net and dropped in for a perfect lob winner.
The shot came in the opening game of third set, with Kyrgios already up two sets to love.
Two years ago at Wimbledon, Kyrgios hit a tweener for a winning drop shot in his upset victory over Rafael Nadal.
Nick Kyrgios has grabbed the early advantage in his intriguing battle of the generations against Radek Stepanek in the opening round of Wimbledon.
The 21-year-old Australian took the first set 6-4 against the 37-year-old Stepanek, who is bidding to become the oldest man to win a Grand Slam match since Jimmy Connors reached the second round of the 1992 U.S. Open at the age of 40.
Kyrgios, who reached the quarterfinals here in 2014, went up 4-1 before Stepanek fought back to 4-4. Kyrgios then held for 5-4 and broke for t
he set, and raced out to a 3-0 lead in the second set.
Stepanek is making his 14th Wimbledon appearance. He made it to the quarterfinals back in 2006.
Serena Williams and Andy Murray both face potentially easy opening matches against lowly ranked opponents on Day 2 at Wimbledon.
Defending women's champion and six-time winner Williams opens play on Centre Court against 148th-ranked Swiss qualifier Amra Sadikovic, making her first appearance in the main draw of a Grand Slam tournament.
Since winning last year's title, Williams has come up short in the majors, losing in the semifinals at the U.S. Open and finals of the Australian and French Opens. She needs one more Grand Slam championship to equal Steffi Graf's Open-era record of 22 titles.
Murray, the 2013 Wimbledon champion, will be up second on Centre Court on Tuesday against Liam Broady, a British wild-card entry ranked No. 235. It's the first all-British men's meeting at Wimbledon since 2001 and first at a Grand Slam since 2006.
