MIAMI - Top seed Alexander Zverev recovered from a slow start to power into the fourth round of the Miami Open with a 7-5, 6-4 win against Australia's Jordan Thompson at Hard Rock Stadium on Monday.
The German was 4-1 down in the first set but then went on a roll, winning eight of the next nine games to progress.
Zverev lost in the opening round at Indian Wells, but with Carlos Alcaraz already out in Miami he will fancy his chances of adding to his list of seven Masters 1000 titles.
"Jordan made it difficult for me for sure. He's a quality player," said Zverev.
"When you're in rhythm, he knows how to break it a little bit. So he did extremely well today. I'm happy with my level from 1-4 onwards," he added.
Third-seed Taylor Fritz also moved into the fourth round beating Denis Shapovalov of Canada 7-5, 6-3.
The American let slip a 5-2 lead in the first set, but regained control with his serve proving too much for Shapovalov.
