Alexander Zverev vs Marcos Giron preview

Second-seeded Alexander Zverev will face USA's Marcos Giron in the first round of the 2025 Halle Open on Tuesday (June 17).
Zverev has had quite a mixed season on the ATP Tour so far in 2025. While the German reached his third career final at the Australian Open in January and won his 24th career singles title at the BMW Open in April, he has suffered various deflating defeats as well.
On Sunday (June 15), the World No. 3 was upset in the Stuttgart Open final by Taylor Fritz, marking his fifth straight defeat to the American since last year's Wimbledon. Needless to say, the 28-year-old is in need of a reversal of fortunes in Halle, where he has finished runner-up twice (2016, 2017).
Giron, meanwhile, has also endured a tough campaign since reaching the Round of 16 in Indian Wells three months ago. The 31-year-old has dropped nine of his last 11 tour-level outings, with his most recent loss coming in the first round of the French Open.

Alexander Zverev vs Marcos Giron prediction

Although Zverev didn't go all the way in Stuttgart, his game has been firing on all cylinders of late. At 6'6", he can fire down huge first serves consistently before following them up with his reliable, deep forehand. The low-bouncing grass is likely to challenge his footwork but he has shown no qualms with faster playing conditions in recent times.
Giron, on the other hand, doesn't have his higher-ranked opponent's firepower, which means that he has to instead rely on his court sense and aggressive intent. The World No. 43 has solid groundstrokes from either wing. That said, he does have an underwhelming serve that will be easy pickings for the second seed during their first-round encounter in Halle.
Pick: Zverev to win in straight sets
