Fritz crushes Fils in Paris, sets up Alcaraz quarterfinal showdown.

Taylor Fritz kept his Nitto ATP Finals hopes alive Thursday night at the Rolex Paris Masters, dismantling sixth-seeded Arthur Fils 6-3, 6-4 on Court Central to reach the quarterfinals.

Fritz, the 11th seed, needed the win far more than his opponent.

Fils had already secured his spot in Turin earlier in the week.

Fritz entered the match sitting 11th in the PIF ATP Live Race To Turin, fighting for one of two remaining spots at the season-ending championship.

The American delivered under pressure.

He fired 14 aces and won 41 of his 51 service points, including 11 of 12 on his second serve.

Fritz faced zero break points across the entire 71-minute match.

He broke Fils for 4-2 in the first set on his first break point and served it out to love.

In the second set, Fils saved two break points in the opening game but was broken in his next service game for 2-1.

Fritz never looked back.

He closed the match to love with a serve and a crosscourt backhand winner on his first match point.

"I played really well," Fritz said on court after the win.

"I did all the things that I feel like I'm doing well. It's how I want to play, it's my style of tennis: serving really well, returning really well and being aggressive."

He credited the court speed for enabling his game.

"Conditions were fast, and I felt like the speed of the court really enabled me to play my game and get rewarded when I stepped in," Fritz said.

Thursday's victory marked Fritz's 100th Masters 1000 win.

It was also his Tour-leading 13th indoor win of the season.

Fritz finished with 29 winners to Fils' 15.

Arthur Fils, who had lived through an emotional Wednesday, had little left in the tank.

The Frenchman secured his place at the ATP Finals in the afternoon, then beat Tomas Machac in the evening and signed the camera with "Ici c'est Paris."

One night later, he faced an opponent who needed the match more.

Fils ruled out any injury after the loss.

"No, no injury," Fils said.

"He just played better than me. I wasn't comfortable."

Fils added: "He was stronger than me."

The loss means Frances Tiafoe did not qualify for Turin on Thursday night.

Fritz now has 3,050 points in the Live Race.

He would pass Rafael Jodar (3,234 points) by reaching the semifinals.

He would pass Tiafoe (3,390 points) by reaching the final.

Tommy Paul, on 2,925 points, is also still in contention but needs to reach the final.

Paul faces Ben Shelton in the quarterfinals in the other half of the draw.

The Nitto ATP Finals feature the top eight singles players and doubles teams in the season-long race.

Two spots remain open for the singles field.

Fritz is now 184 points behind ninth-placed Jodar in the Live Race.

Awaiting Fritz in the quarterfinals is second seed Carlos Alcaraz.

Alcaraz advanced without playing after Matteo Berrettini withdrew due to injury ahead of their third-round clash.

Alcaraz is aiming to reach the last four in Paris for the first time in his career.

The Spaniard holds a 6-1 Lexus ATP Head2Head series lead against Fritz.

"I am excited for it," Fritz said about facing Alcaraz.

"Excited for the opportunity. That's why I have gotten to this point in the tournament. I knew I was probably gonna have to go through him if I wanted to [have the chance] to make Turin. So, I'm ready to play."

The quarterfinal is scheduled for Friday.

Fritz rallied from a set down in his first two matches in Paris but was in control from the start against Fils.

The American claimed an early break at 3-2 in the opening set to move ahead.

The 11th seed then struck again to break Fils at 1-1 in the second set.
