Caesars Sportsbooks rewards +130 payout for bettors backing both players to win a set.

Current Form:

Frances Tiafoe earned his second top-10 win of the year and 15th of his career after outgunning Felix Auger-Aliassime 3-6, 6-3, 7-6. It was a signature win for Tiafoe, who showcased her fighting spirit and clutch genes in this thrilling win over the world’s No.4. Tiafoe, who reached the quarterfinals at Stuttgart, raised his grass-court record to 5-1 in 2026.

Daniel Altmaier salvaged his 8th top-10 win after grinding down Daniil Medvedev 6-4, 6-7, 6-4. Altmaier, who is averaging 11.3 aces per match in Halle, fired 15 aces and won 76 percent of his first serves to hold 15 of 16 service games. He also captured two crucial breaks, including the point that clinched the win in the 10th game of the third set.

Matchup: Tiafoe, who defeated Altmaier for the fourth time in Stuttgart a week ago, rolls into the semis as the favorite at -280. However, bettors shouldn’t sleep on Altmaier, who has brought an unplayable serve in Halle.
