Alexander Zverev, the world’s No. 4-ranked player, is competing in the Miami Open. He will face Argentina’s Francisco Cerundolo in the Quarterfinal on March 26.
Zverev Favoured in Quarterfinal Match
Zverev is considered the favourite against Cerundolo, who is ranked No. 19 on the ATP. Should Zverev win, a difficult matchup against Jannik Sinner likely awaits. Sinner is the world’s No. 2-ranked player and the favourite to win the Miami Open, particularly with Carlos Alcaraz having already been knocked out.
Before any potential match with Sinner, Zverev must first defeat Cerundolo.
Girlfriend’s Support Amidst Previous Split Rumours
Zverev will have the support of his girlfriend, Sophia Thomalla, in person. Zverev and Thomalla have been together since 2020. There were rumours that the couple split up at the end of 2025 or in early 2026, after Zverev was spotted alongside Caroline Daur at the Australian Open while Thomalla was not present. However, it has since become clear that Zverev and Thomalla are still seeing each other.
Zverev and Thomalla have a joint Instagram account of their dog named Mishka, which they have been posting on throughout the Miami Open. Thomalla has also been seen at Zverev’s matches.
Thomalla Promotes New Show
Thomalla was seen on a beach of late, which was likely in Miami. She posted on Instagram on March 26, with the caption: “It’s already starting again…. New Season incoming…”
Thomalla appears to be promoting a new show that she is hosting, called “Are You The One?” What’s catching attention is the violet dress she’s wearing in the post.
Thomalla is expected to be in the grandstands for Zverev’s match against Cerundolo on Thursday.
Potential Rankings Boost for Zverev
If Zverev were to beat Cerundolo and then the winner of Jannik Sinner and Frances Tiafoe, he would presumably be the favourite in the Miami Open final against either Jiri Lehecka or Arthur Fils. If Zverev were to win the Miami Open, he might surpass Novak Djokovic at No. 3 in the world rankings.
