After battling Borna Coric for three sets in his Miami opener, Alex Zverev closed Sunday's evening session in Hard Rock Stadium with a much more comfortable victory against American Mackenzie McDonald.
In a 6-2, 6-2 cruise, the German had break points in each of his first six return games, converting in four of them as he raced to a 6-2, 4-0 lead. He wiped away the only break point he faced, with McDonald's opportunity coming in a low-leverage situation as he trailed by a double break at 4-1 in the opener.
"I'm happy to be finding my rhythm a little bit," Zverev said after the one-hour, 13-minute victory. "I'm happy with getting easier wins, as well. Just generally happy to be in the fourth round. I think the tournament is going to get tougher from here, but I'm ready."
Zverev improves to 3-0 in his ATP Head2Head against the American, taking all three meetings in straight sets, including in Montpellier in February. McDonald, currently five spots off his career-high ATP Ranking at World No. 54, was playing in the Miami third round for the first time.
The German had success pinning his opponent deep behind the baseline, enabling him to dictate the rallies both on serve and return. He also hit 10 aces in the match and won more than 70 per cent of his service points.
"The most important thing against Mackenzie is to play deep, that's the number one priority," Zverev said of his tactics. "Because he's somebody that tries to go to the net, tries to play aggressive. So try to take that away from him. It worked out well and I'm happy to be through."
The 24-year-old has never lost in three appearances in the Miami third round, previously reaching the 2018 final and the 2017 quarter-finals.
