Rare rain might have interrupted play at the BNP Paribas Open on Tuesday but there was nothing gloomy about Holger Rune’s performance as the Dane reached a second straight quarterfinal in the desert.

Rune flashed his entire repertoire in a 6-4, 6-4 win over Stefanos Tsitsipas that upped his record against the Greek Grand Slam finalist to 4-0. He pulled off perhaps one of the shots of the year in the second set, a tweener lob.

The World No. 13 is also now 19-4 against players with one-handed backhands. He indeed seemed to direct plenty of his shots to Tsitsipas’ one-hander on the higher bouncing courts at the Indian Wells Tennis Garden.

“It was an extremely good match from my side from start to finish,” Rune, who had to retire at his last tournament in Acapulco due to food poisoning, said in a TV interview. “I stayed very committed to my game plan. “Mentally I was very, very good. I think that’s what made the difference. How composed I could stay.”

Rune saved the first two break points of the contest but after that was the one constantly applying pressure on the serve of Tsitsipas, who headed into Indian Wells riding high after winning a title in Dubai. He authored a reflex forehand winner down the line off a Tsitsipas smash in the first set and more magic came in the second.

Rune broke serve for 3-2, engineering back to back passing shots from yards behind the baseline. It that wasn’t enough, the tweener lob that landed in the corner — when down a break point at 4-3 — is sure to be replayed over and over on highlight reels.

“That’s the first thing I’m going to check when I’m going to check my phone,” Rune smiled.

Rune, who had been 2-10 in his previous 12 matches against top 10 opposition, next meets Tallon Griekspoor. At Stadium 2, Griekspoor reached his first Masters 1000 quarterfinal by beating Japanese qualifier Yosuke Watanuki 7-6 (4), 6-1.

Griekspoor upset top-seed Alexander Zverev in the second round in a thriller and there’s been no letdown for the Dutchman. He told BNPParibasOpen.com that he has his eyes set on the Top 10 and making the quarterfinals will bump up his current ranking of 43rd.

The big serving Griekspoor frequently plays tiebreaks, so he was in familiar territory in the first set. Before the tiebreak, he created break points in two different games and also had 0-30 on the Watanuki serve. The 28-year-old couldn’t break through and when Watanuki led 4-2 in the tiebreak, it looked like the World No. 349 would steal the set.

However, errors crept into his game and Griekspoor took advantage. Still, Watanuki — hit hard by a knee injury last year — continued to smile on court, even when the match ended. His booming baseline strokes and personality made him a fan favorite at the Indian Wells Tennis Garden. Griekspoor sportingly told him at the net, “Great tournament. Great playing. Keep going. Stay healthy.” Griekspoor’s great tournament continues, and he owns a 2-0 record against Rune.

In a match scheduled for the day session but that finished just past 9:30 p.m. due to multiple rain stoppages, 20-year-old Arthur Fils overcame California’s Marcos Giron 6-2, 2-6, 6-3 to become the youngest French Masters quarterfinalist since Richard Gasquet in 2006.

The 31-year-old Giron, meanwhile, missed out on becoming the oldest first time Masters quarterfinalist since the series began in 1990. Fils — who combines huge power with outstanding court coverage — feasted on Giron’s second serve in the opening set. Giron beefed up his forehand in set two as Fils’ error count rose but the latter stormed out to an early 3-0 lead in the third. He slammed a pair of aces to hold in the first game of the decider as part of a stretch where he won eight consecutive points.

Not even a vocal Giron supporter in the stands could spark a turnaround. A confident Fils even crunched a second serve ace to hold for 5-2 in the third. Still, Giron achieved his longest stay in the desert and should see his ranking inch up to around No. 45.
