TURIN, Italy: Carlos Alcaraz came under extreme pressure before overcoming Taylor Fritz 6-7(2) 7-5 6-3 in a thrilling match at the ATP Finals on Tuesday, before Italy’s Lorenzo Musetti beat Alex de Minaur in a dramatic encounter.

Musetti’s 7-5 3-6 7-5 win means that all four players can still make the semifinals, with the Italian facing Alcaraz, on two wins from two, and Fritz taking on De Minaur on Thursday to close out the Jimmy Connors Group, with the top two making the last four.

Last year’s finalist Fritz played the tennis of his life, as both men served up the best encounter of the season-ending championships so far, but the American ran out of steam as Alcaraz turned on the style and took the deciding set with ease.

Alcaraz and Fritz had won their opening group matches, and the Spaniard looked in real trouble when the American took the opening set in a tiebreak. Alcaraz faced break points in the second set but rallied back to draw level.

Fritz began to tire, and Alcaraz broke to lead 4-2 in the final set before wrapping up the win in two hours and 48 minutes by serving out to love.

“It was pretty tight, I was struggling more than him in the first set,” Alcaraz said. “I wasn’t serving well, and I think he was pretty comfortable from the baseline, from everywhere.”

Alcaraz needs one more victory to guarantee the year-ending world No. 1 spot.

Tuesday’s clash was a battle from the opening game, with Fritz taking nine minutes to hold after hitting three aces but also facing two break points. The American forced three break points in the next game before the pair traded breaks.

Fritz raced into a 5-2 lead in the tiebreak and smashed two aces to take the set. At 2-2 in the second, Alcaraz was rattled, his drop shots which earlier beat Fritz began to fall short but, after losing advantage five times, the Spaniard held on.

Alcaraz got lucky with a shot that hit the net but crept over in the final game of the second set and broke to take the match to a third, where the Spaniard outclassed an exhausted Fritz.

“I was really relieved after the win because of everything I went through during the match,” Alcaraz said.

“I wasn’t feeling the ball as well as I was in the first round, but I’m really happy that I found a way to come back.”

Magical Musetti

Musetti looked down and out with De Minaur serving for the match but those few who left early to beat the traffic missed out on a stunning comeback.

The Italian took the first set after breaking serve at 5-5, and De Minaur survived three break points in the second set opener before finding his first break points of the match at 4-4 and making them count.

De Minaur had control in the final set at 2-0 up, but when it came to the crunch Musetti found energy from somewhere to pull off a great escape, as defeat would have meant elimination.

After two spectators died from cardiac arrests on Monday, play was held up again for a medical emergency in the crowd in the final set of Musetti’s win. The match was suspended for several minutes before resuming. Local media reported a fan was transported to hospital in a serious but not life-threatening condition.
