PARIS (AP) The Latest from the French Open (all times local):
Nick Kyrgios of Australia beat Philipp Kohlschreiber of Germany in straight sets to reach the second round of the French Open.
The 18th-seeded Kyrgios hit 20 aces on his way to the 6-3, 7-6 (4), 6-3 victory.
Kyrgios argued lengthily with the umpire in the second set when a key call went against him when he had a break point for 5-4, but he regained his focus to take the tiebreaker with an ace, on his third set point.
Former U.S. Open champion Juan Martin del Potro has won his first match in five years at the French Open.
Featuring at the clay-court major for the first time since 2012, Del Potro won an all-Argentine contest against qualifier Guido Pella 6-2, 6-1, 6-4.
Del Potro showed no sign of the shoulder and back problems that hampered him at the Lyon Open last week and did not face a single break point.
Del Potro's best result at Roland Garros is the semifinals in 2009, the year he won at Flushing Meadows.
Fifth-seeded Elina Svitolina hit a crosscourt forehand winner on match point to win the first match on Court Suzanne Lenglen and seal her spot in the second round of the French Open.
Svitolina converted all three break points and hit 25 winners to prevail 6-4, 6-3 over Yaroslava Shvedova, a two-time quarterfinalist in Paris.
Svitolina is coming off the Rome title two weeks ago and is an outside favorite in Paris, where she made it to the quarterfinals two years ago. The Ukrainian has won three other tournaments this year.
''I was very happy with the way I handled the pressure,'' she said. ''It's the first time that I have won four titles and two big ones so it's given me a lot of confidence.''
After becoming No. 1 last year, Andy Murray has been struggling in 2017, but he'll try to right himself starting in the French Open's first round against Andrey Kuznetsov on Tuesday.
Joining Murray, the runner-up a year ago in Paris, in finally getting going on Day 3 will be 2015 champion Stan Wawrinka, who meets Jozek Kovalik.
The showdown of the day should be 15th-seeded Gael Monfils of France against Dustin Brown of Germany. Both hit highlight-worthy shots on a regular basis.
In the women's draw, No. 3 Simona Halep is up against Jana Cepelova, and No. 5 Elina Svitolina plays Yaroslava Shvedova.
First up on Court Philippe Chatrier is seventh-seeded Johanna Konta against Su-Wei Hsieh.
