World No. 25 Stefanos Tsitsipas is moving to the Six Kings Slam 2025 quarterfinals with a determined 21-17 record and seems to draw inspiration from his 2025 Dubai win, in which he ended an ATP 500 final losing streak and quickly returned to the top 10 [atptour.com]. His 7-6(4), 6-3 semifinal victory over Lorenzo Sonego in Dubai was not only an easy win but also his 350th tour-level win, a milestone that reflects in a similar way to Federer's flawless rise. At the same time, a tough 6-4, 2-6, 6-4 quarterfinal battle against Karen Khachanov—his 2017 Shanghai conqueror—was a throwback to the time when Tsitsipas amazed with his backhand handiwork [atptour.com].
After letting go of his Wimbledon dream and withdrawing from Shanghai, Tsitsipas is making a comeback in Riyadh and shows a 62% win rate in short rallies (according to Tennis Abstract), which helps him transform his opponent's aggression into his own dazzling counters. His trademark one-hander, which @TennisHypeMedia on X called "the torch for one-handed backhands" while #TsitsipasRising was trending, neatly cuts through Sinner's flat power [x.com]. Upon Dubai victory, Tsitsipas told ESPN, "I am reigniting my fire—Riyadh is doing it again," while at the same time a new Goran Ivanisevic coaching chapter was being rumored after the Wimbledon critique [espn.com].
He is at his best when he wins 72% of the points on the first serve (ATP statistics), which he does mostly at indoor venues where he also averages 8.2 aces per match [atptour.com]. Tsitsipas, who rallies are on average 5.1 shots long, diversifies his game and thus manages to convert as many as 42% of his break points along with 1.6 breaks per match, which makes it hard for Sinner's game to remain steady [atptour.com]. Sinner's speed is a big factor in Tsitsipas's movement, who has just recovered from a back twinge and had to withdraw from Shanghai [atptour.com], yet the tactical genius of Tsitsipas—which he sharpened while defending in Monte-Carlo—reveals the opponent's fragilities on the second serve. This brings to mind Sampras's flawless style of play when he faced Agassi, Tsitsipas, similarly, is finding the perfect balance between art and revenge.
To put it simply, bettors looking at tie-breaks should consider that Tsitsipas has a 62% win rate there and can therefore back the set-split market when Tsitsipas is playing at the Six Kings Slam 2025, especially given his 6-3 H2H advantage [atptour.com]. First of all, Rome finals and French Open semis were just the prelude to what is depicted as Tsitsipas's biggest and most emotional quest for glory at the upcoming event, therefore, powered with the spirit of a warrior, Greek Tsitsipas might just overshadow Sinner's run. In line with the hashtag #TsitsipasRising on X, Riyadh is the perfect place for the artist to make history—with lasers from his backhand lighting up the night sky.
🇮🇹 Jannik Sinner: form and statistics
Jannik Sinner, the World No. 2, reached the quarterfinals of the Six Kings Slam 2025 with an impressive 43-6 record. His Beijing 6-2, 6-2 demolition of Learner Tien was the highlight of the evening as it not only secured a third 2025 title for Sinner but also resembled his Australian Open-Wimbledon double [atptour.com]. It was unfortunate that he had to retire from the third round in Shanghai against Tallon Griekspoor due to cramps, but his 6-1, 3-6, 6-3, 6-4 US Open semifinal match against Felix Auger-Aliassime which earned him his 300th win was a remarkable feat and a clear indication of his toughness after the suspension [atptour.com].
Sinner, the reigning Riyadh king, effectively uses his 68% break point conversion (according to Tennis Abstract) to terrorize his opponents indoors where his flat strokes are most effective in hitting the base of the court. After Beijing, #SinnerRising has been mentioned 15K X times and @TheTennisLetter was one of the first to notice and praise this by saying "56 of 61 wins—consistency nuts" [x.com]. During the doping ban period, Sinner tweeted on X, "Riyadh's throne calls—let's defend." His 74% first-serve points won and 5.7 aces per match are the reasons his serves are hard to break [atptour.com].
Nevertheless, Tsitsipas's 42% returns are putting more pressure on Sinner's 55% second-serve holds as we have just seen from their 6-3 H2H loss [atptour.com]. While Sinner's 2.5 breaks per match is a result of Tsitsipas's errors, the latter's low unforced rate (18 indoors) is testing Sinner's stamina following his collapse in Shanghai [atptour.com]. His amazing performance from 2022-23 which is now a 90% win clip is the main reason why he is able to drive 4.9-shot rallies [atptour.com].
Information about the game and the players shows that Sinner's 70% hold rate is the key for the success of ace props in the Sinner Six Kings Slam 2025 event, while 65% tie-break wins are the main indicator of straight-sets victory [atptour.com]. After losing the French Open final to Alcaraz, Sinner's Slam march is met with Tsitsipas's brilliant play, thus resulting in the script of the Italian steel verses the Greek poetry at Riyadh's glare [atptour.com]. On the social media site X, #SinnerRising mental toughness is derived from his position as the US Open runner-up and the main theme of the discussion is his capacity to defend the crown as well as a link to his unbreakable rise where each forehand can be heard.
