Richard Gasquet def. Andy Murray
Andy Murray returned to the court for a singles match Monday for the first time in more than six months, but it was an unsuccessful return.
Richard Gasquet earned a straight-sets victory over the British star, who hasn't competed in a single match since the Australian Open while dealing with multiple hip injuries. He had appeared in a few doubles matches in this span but hadn't been able to play on his own.
This return could also be short-lived, as he said after the match he won't be playing singles at the U.S. Open, per Ben Rothenberg of the New York Times.
Murray wasn't at his best in Cincinnati, struggling with his accuracy while getting only 54 percent of his first serves in play. Gasquet took advantage by winning 15 of 26 returns on second serves.
Still, the veteran did have some good moments where he showcased his range:
The 32-year-old might need more time to recover, but he isn't far from being a competitive player once again in 2020.
Radu Albot def. Marin Cilic
It was a day of missed opportunity for Marin Cilic, who was bounced in the first round after a loss to Radu Albot.
The No. 14 seed lost in straight sets, but he had a lot of chances to win the second set:
He also had six break opportunities against Albot but couldn't convert any of them, allowing the underdog to stay in front and eventually seal the win in the tiebreaker.
It added up to arguably the biggest win of the year for Albot, who continues to have one of the best runs of his career. The 29-year-old entered the month with the highest ranking of his career at 39, and he could continue to rise with more big wins over top competitors.
The bottom half of the bracket is wide-open after Rafael Nadal withdrew from the event, and Albot could make a deep run if he continues to play well.
As for Cilic, he is now just 15-13 on the season and has only reached the quarterfinals of two tournaments.
Maria Sharapova def. Alison Riske
Maria Sharapova entered this event on a three-match losing streak and hasn't won more than one match in a tournament since January.
She looked much better in the first round at Cincinnati, forcing Alison Riske to move all around the court in the first set:
Riske appeared to take control in the second set going up 4-1, but Sharapova stormed back by winning five of the next six games to get back in charge. Although she couldn't close things out with her serve, she earned the win in the second-set tiebreak.
She showed an impressive skill set during the match, especially with her winners:
Though things get much tougher in the next round with a matchup against top-seeded Ashleigh Barty, Sharapova should remain a threat in this tournament and the U.S. Open.
