Frances Tiafoe downs Jan-Lennard Struff to win Stuttgart; will break Top 10

WATCH: Frances Tiafoe sealed his first grass-court title in style, beating Jan-Lennard Struff in a third-set tiebreak.

On Monday, American Frances Tiafoe will be the ATP’s newest Top 10 player—and boy, did he earn it.

Tiafoe saved a match point to beat Germany’s Jan-Lennard Struff in Sunday’s final at the ATP 250 Boss Open in Stuttgart, 4-6, 7-6(1), 7-6(8), and capture his third career ATP singles title. It’s also his first career grass-court title.

Tiafoe will make his Top 10 debut on Monday at No.10. With compatriot Taylor Fritz at No. 8, it will be the first time two Americans have been in the Top 10 in 11 years. In May 2012, Mardy Fish and John Isner were No. 9 and No. 10, respectively.

"To win the title in a match like that and be in the Top 10,” Tiafoe said after the match, “that's a lot of emotions for a guy like me.”

Tiafoe’s crowning moment was a microcosm of his week in Germany as a whole: In five matches, six of the 10 sets he played during the week were tiebreaks. In addition to saving championship point in Sunday’s match against Struff, he saved six set points in the second set of his 6-3, 7-6(11) win over Marton Fucsovics.

He didn’t break Struff’s serve for the duration of the match—the German hit 28 aces—but a five-point run at the start of the second-set tiebreak helped spur the American into a decider.

"It was an incredible match," Tiafoe said. "I didn't break him for two hours, Struffi was serving well today. It was just super-tough. On that match point, I don't know how I got the ball over the net, but I'll take it. It’s good to walk away with the title.”

Tiafoe now owns a title on all surfaces, having won his first clay-court title earlier this year in Houston. Struff, meanwhile, dropped to 0-3 in his career in ATP finals and 0-2 this year. The 33-year-old was also runner-up to Carlos Alcaraz at the Masters 1000 event in Madrid in May.
