MASON, Ohio — Juan Martin del Potro advanced to the second round of the Western & Southern Open with a 3-6, 7-6 (1), 6-0 upset of 10th-seeded Tomas Berdych on Tuesday.
The 30th-ranked del Potro shook off a first-set loss, jumping out to a 4-1 lead in the second set before settling for a win in the tiebreak, which he led 5-0 and clinched with an ace. He built on his momentum by rolling through the third set against the Wimbledon semifinalist, improving to 12-0 in first-round matches this season.
Berdych was playing his first match since withdrawing from last week’s Rogers Cup in Montreal with a rib injury.
Ninth-seeded David Goffin became the first seeded man to be knocked out in Cincinnati, falling to Nick Kyrgios, 6-2, 6-3 in a first-round match. Kyrgios will meet qualifier Alexandr Dolgopolov in the second round after Dolgopolov defeated Kevin Anderson 6-4, 7-6 (6).
In women’s first-round action, Karen Khachanov beat Diego Schwartzman 6-1, 1-6, 6-3, and Ashleigh Barty beat Varvara Lepchenko, 6-4, 6-4 in a matchup of two qualifiers.

MADRID — Andy Murray will play in a second-tier Challenger Tour tournament hosted by Rafael Nadal’s tennis academy.
The tournament says Murray has accepted an invitation to play.
Murray, a three-time Grand Slam champion, had hip surgery in January. He returned to the court in June playing doubles – including at Wimbledon – before moving back to singles this month. The former No. 1 lost to Richard Gasquet in Cincinnati and to Tennys Sandgren in Winston-Salem, both in the first round.
Murray has not played on the Challenger Tour since 2005. His opener at the tournament in Mallorca, Spain, will be his 35th match in the lower division.
The tournament starts on Aug. 26.
