Michael Zheng vs Olle Wallin preview
Seventh-seeded Michael Zheng will face Sweden's Olle Wallin in the second round of the 2025 Tiburon Challenger on Thursday (October 2).
Trending
A couple of weeks ago, Zheng achieved his career-high singles ranking of 227 following his second-career ATP Challenger Tour title in Columbus. The 2024 NCAA Division-I singles titlist has won 25 of his 33 competitive outings in his first full season on the Challenger circuit. The 21-year-old is one of the outside favorites to win the Tiburon Challenger title and started his campaign on a positive note earlier this week, downing Great Britain's Oliver Tarvet 6-4, 6-3 to reach the second round of the 75-level event.
Wallin, meanwhile, is ranked outside the men's top 400 ATP rankings, which forced him to qualify for this week's Tiburon Challenger. The 23-year-old has made the most out of the opportunity, though. After not dropping a single set in his two qualifying wins, the Swede reversed a set and a break deficit in his first-round match to beat the higher-ranked Martin Damm Jr. 2-6, 7-6(5), 6-3 in just over two hours.
Michael Zheng vs Olle Wallin head-to-head

Michael Zheng vs Olle Wallin prediction
At 6'2, Zheng boasts of not only a big first serve but some blistering groundstrokes from both wings as well. The World No. 228 American also moves deceptively well for someone of his height, making him one of the most dangerous upcoming players, as far as the new ATP tennis prototype of all-around playing styles with significant physicality is concerned.
Wallin is also an adept server at 6'3, with his down-the-T first serve being very hard to retrieve. That said, the qualifier struggles with inconsistency in his service games. More importantly, he is likely to be tired from his campaign at the Tiburon Challenger thus far, giving Zheng a considerable edge in this match-up.
Pick: Zheng to win in straight sets.
