Tommy Paul defeated Milos Raonic 6–4, 7–6, 6–7, 6–4 in the first round of Wimbledon 2023 on grass, confirming his status as the pre-match favourite with odds of 1.52 against Raonic's 2.73. Paul's victory came in a competitive encounter that saw the match extend to four sets, with the third set decided in a tie-break before the American secured the decisive fourth set to advance. The result underscores Paul's growing grass-court credentials and represents a solid opening statement at the All England Club, whilst Raonic's early exit marks a disappointing campaign on a surface where he has historically performed well.
