Defending champion and world No. 1 Jannik Sinner begins his Wimbledon title defence with a five-set comeback victory after an early scare. Across multiple reports, Sinner is pushed to a deciding set against Serb Miomir Kecmanovic in his opening-round match on Centre Court. The match goes to five sets, with Sinner staging a recovery after trailing midway through the contest. One outlet notes the result as 4-6, 6-3, 6-7(6), 6-2, 6-3, indicating that Kecmanovic wins the first set and also takes the third set in a tiebreak. Sinner then wins the fourth and fifth sets to secure passage into the second round, avoiding what outlets describe as the risk of an unwanted early exit or historic shock. Reports also frame the match as part of a busy first day of Wimbledon, with Sinner’s win keeping his title defence alive.
