Alexander Zverev looks to go one further than his runner-up showing last year in Acapulco.

Zverev Races To Finish Line In Acapulco Opener

Auger-Aliassime advances on Tuesday

Second seed Alexander Zverev shook off a slow start and rounded into form on Tuesday at the Abierto Mexicano Telcel presentado por HSBC, moving past qualifier Jason Jung of Chinese Taipei 7-6(6), 6-1 to reach the second round in Acapulco.

”The longer the match went, the better I started to play,” Zverev said in his on-court interview. “My serve is something that I need to improve, but all in all, it’s the first round that I expected. It could have been a lot tougher.”

The German quickly trailed 0-3 in the first set after three double faults led to him being broken in his opening service game. He found the range on his groundstrokes and broke Jung at 2-4 to get the set back on serve, which eventually moved into a tie-break.

Zverev reached set point at 6/5, but squandered his chance with an ill-advised drop shot. A backhand from Jung at 6/6 found the top of the tape and Zverev grabbed the early advantage with an aggressive approach.

The second seed relaxed considerably in the second set, breaking Jung three more times to advance in 73 minutes. Last year’s runner-up (l. to Kyrgios) will face another qualifier in the second round when he meets American Tommy Paul.

Auger-Aliassime has won nine of his past 11 matches after finishing runner-up this month in Rotterdam (l. to Monfils) and Marseille (l. to Tsitsipas). Awaiting him in the next round is Brit Kyle Edmund, who took his second ATP Tour title earlier this month in New York (d. Seppi).

Fifth seed John Isner hammered 22 aces and didn't face a break point in dismissing German wild card Mischa Zverev 6-3, 7-6(4). He'll take on a qualifier in the next round when he faces fellow American Marcos Giron.
