Czech rising star Jakub Mensik hit 11 aces and rode a dominant third set to a 7-6 (3), 2-6, 6-3 upset of No. 2 seed Jannik Sinner of Italy at the Qatar ExxonMobil Open quarterfinals on Thursday in Doha.

The sixth-seeded Mensik won 14 of his 16 first-service points in the third set and 49 of 60 overall (81.7%) while saving 5 of 7 break points in the match. Sinner, who fell in the semifinals of the Australian Open, missed the final in back-to-back starts for the first time since the summer of 2024.

No. 1 seed Carlos Alcaraz of Spain now has a clearer path to the title at the ATP 500 event, though he survived a scare of his own in the quarterfinals when he rallied past Russian seventh seed Karen Khachanov 6-7 (3), 6-4, 6-3. Alcaraz had a 41-14 edge in winners to overcome his 34 unforced errors.

Alcaraz’s semifinal opponent will be No. 5 seed Andrey Rublev of Russia, a 6-3, 7-6 (2) winner over Greece’s Stefanos Tsitsipas. Mensik will battle Frenchman Arthur Fils, who upset Czech eighth seed Jiri Lehecka 6-3, 6-3.

Delray Beach Open

No. 4 seed Learner Tien hit 20 aces among his 51 winners to fight past Serbia’s Miomir Kecmanovic 6-4, 6-7 (4), 7-6 (5) in Delray Beach, Fla.

Kecmanovic saved four match points — one in the 12th game to force a tiebreaker, then three more after going down 6-2 — but he could not save a fifth. Tien’s quarterfinal opponent, No. 8 seed Frances Tiafoe, also needed three sets to turn back qualifier Zachary Svajda 6-4, 3-6, 7-5, saving 5 of 6 break points along the way.

The evening matches in Florida pit No. 5 seed Tommy Paul against Australian Adam Walton and No. 1 seed Taylor Fritz against Spain’s Rafael Jodar.

Rio Open

Portuguese lucky loser Jaime Faria kept his week going by beating Bosnia and Herzegovina’s Damir Dzumhur 7-6 (1), 6-4 to advance to the quarterfinals in Rio de Janeiro.

Faria, who hit 26 winners and had to get past 29 unforced errors, is joined in the next round by No. 8 seed Tomas Martin Etcheverry of Argentina, who defeated Lithuanian qualifier Vilius Gaubas by an identical 7-6 (1), 6-4 scoreline.

The late matches in Rio see third-seeded Joao Fonseca of Brazil take on Peru’s Ignacio Buse and Italian Matteo Berrettini oppose Serbian lucky loser Dusan Lajovic.

Tyler Reddick’s victory in the 2026 Daytona 500 scored massive ratings for Fox Sports, which saw an 11% increase over last year’s race.

The 7.489 million viewers for the race out-paced every non-prime Winter Olympics window on broadcast and cable and was the most-watched NASCAR race since the 2023 Daytona 500 (8.173 million). The peak viewership from 5:30-5:45 p.m. ET on Sunday drew 9.154 million viewers.

They tuned in to see Reddick score a victory for Michael Jordan’s 23XI Racing by passing leader Chase Elliott on the final turn.

The 30-year-old Corning, Calif., native went high and swooped low off Turn 4 to beat Ricky Stenhouse Jr. by 0.308 seconds as the lead group wrecked wildly before reaching the flagstand.

Joey Logano finished third, followed by Elliott and Brad Keselowski.

“Last year was really hard for us, hard for me,” said Reddick, who became the fourth Daytona 500 winner not to lead until the last lap. “When you’re a Cup driver and you get to this level and drive for Michael Jordan, you’re expected to win every single year.”

Elliott settled for his second Top 5 finish in 11 starts at Daytona.

“This really sucks to be that close,” Elliott said, “come off Turn 4 with the lead and not finish it off.”
