Here’s our Frances Tiafoe vs Daniel Altmaier prediction. This article will also contain a Frances Tiafoe vs Daniel Altmaier pick.

Frances Tiafoe vs Daniel Altmaier Preview

Frances Tiafoe has reached the semifinals of the Halle Open on his debut. The American stunned Felix Auger-Aliassime in a thrilling quarterfinal match. The match went the distance, and Tiafoe, who was a break down in the third set, saved three match points in the final set tiebreak to prevail 14-12.

Tiafoe hit 5 aces and withstood 25 aces from the Canadian’s racket. Tiafoe landed 67% of first serves in play and won 70% of first serve points (51/73). Tiafoe won 61% of second serve points (22/36) and saved seven of nine break points on his serve. Tiafoe improves from last week’s quarterfinal showing in Stuttgart and now holds a 27-13 record this season. He owns one grass-court title in his career.

Daniel Altmaier reached his first career semifinal on grass at age 27 and fittingly, it is on home soil. The German has upset some big names to get here. In the first round, he took out big-hitting Nikoloz Basilashvili in straight sets, but not many people could fathom the magnitude of the upsets he pulled off in the next two matches. He beat two former Wimbledon semifinalists.

Altmaier knocked out Hubert Hurkacz in the Round of 16, earning a late break in the third set to prevail 3-6, 6-3, 7-5. Then he needed another three-set victory against Daniil Medvedev, taking almost three hours of play to book his spot in the last four of the Halle Open. And after losing to Tiafoe in Stuttgart this past week, Altmaier has the chance to avenge that defeat.

Frances Tiafoe vs Daniel Altmaier Head-To-Head

Tiafoe and Altmaier have met four times. Tiafoe has won all four meetings. They met at the Stuttgart Open last week and Tiafoe needed three sets to see off the German.

Frances Tiafoe vs Daniel Altmaier Prediction

This tournament has been very kind to some German players in the past and Altmaier’s hard work could be rewarded if history is anything to go by. And if there is a player who has surprised us more during this grass-court swing, it has to be Altmaier. For years, his game belonged almost exclusively on the dirt, yet he has produced some outstanding tennis at the Halle Open. Look, Tiafoe is the rightful favorite here and he just beat Altmaier a week ago in Stuttgart (that was a slugfest though and far from a stroll), but I reckon Altmaier appears to be riding something bigger than form. He’s discovered a new dimension to his game on grass and I’m calling the upset in this one.
