World no. 13 Felix Auger-Aliassime with the season record 41-21 just one title away, has come to the Round of 32 at Swiss Indoors Basel 2025 after his stellar run in Brussels. The 2-1 win over Jiri Lehecka (7-6(2), 6-7(6), 6-2) that was full of tough rallies resembled a similar pattern of his 2022 Antwerp victory, a sort of ATP Finals comeback.
The two times (2022-23) Basel player of the year overwhelmed Damir Dzumhur 7-6(3), 4-6, 7-6(5) in 2 hours and 54 minutes, saved three match points and thereby, raised his indoor hard record from this season to 8-1 (including the 100% Adelaide run). His past in Basel glistens with the double of back-to-back titles, and he has lost only one set on the way to the final (2023) where his baseline accuracy was one of the reasons why he was able to neutralize his rivals on the fast courts. Felix Auger-Aliassime has achieved 65% success for the short volleys (according to Tennis Abstract) and has won 88% of the points with the first serve (ATP stats), which makes him very hard to break. In 2025 with 15 victories in the deciding sets he is on the same level as Alcaraz and Borges thus, supporting his run to the Turin Finals after reaching the US Open semifinals. @TennisFanatic23 on X is quite enthusiastic of his performance: "FAA's backhand slices through indoors like butter—untouchable!" while fans are also talking about his glow after the wedding which took place in September. From the tactical point of view, his 4.8-shot rally average and 42% return points can be used effectively to counter Diallo's aggressive serving, and on the rapid surface in Basel, you can see he is turning from defense to offense. Auger-Aliassime's 76 indoor hard wins since 2020 (most on Tour) grant a clear edge, though Diallo's power tests his stamina in extended exchanges.
For those placing bets, Auger-Aliassime's 88% hold rate is a good indication of the success of ace props at -2.5 games handicap (1.845 odds), which is a smart move in his Felix Auger-Aliassime Swiss Indoors Basel 2025 performance. The 80% deciding-set rate is more inclined towards the straight-sets scenario but what if there was a contrarian underdog that takes the set to offer you some value? Pursuing the title of the best indoor Canadian player, Auger-Aliassime has not only the tactical brilliance of a chess master but also the emotional rage of a warrior in him which makes this legendary showdown a treat for the fans who are anticipating some explosive actions of the Great White North.
