Casper Ruud delivered a stunning performance at the ATP Finals in Turin, defeating Carlos Alcaraz in straight sets with a score of 6-1, 7-5. This victory marks a significant milestone for the Norwegian player, as it represents his first career win over the two-time Wimbledon champion. Alcaraz, who had previously dominated their encounters with a 4-0 head-to-head record, struggled to find his rhythm in this match. The young Spaniard, who has claimed four Grand Slam titles, including his first against Ruud in the 2022 US Open final, faced challenges from the outset. Ruud noted that he was aware Alcaraz might be dealing with a cold, which could have impacted his performance. This unexpected defeat puts Alcaraz in a difficult position as he begins his campaign at the ATP Finals.
