Stan Wawrinka and Matteo Berrettini meet in the Wimbledon first round on Wednesday, a best-of-five grass-court clash that pits a former champion against a player finding his rhythm. The data and the betting market heavily favour Berrettini, with the Italian's superior recent results and overall season efficiency suggesting he should have too much for the Swiss veteran. The key question is whether Wawrinka's grass-court nous can trouble a player who has been winning consistently at the highest level.
Berrettini's overall season record of 15-12 comfortably outweighs Wawrinka's 8-14, and the margins in key areas are significant. The Italian holds serve 85% of the time while Wawrinka is at 83%, but the real difference comes on return: Berrettini wins 19% of return games compared to just 13% for the Swiss. That converts into more break-point chances, with Berrettini converting 41% of them against Wawrinka's 28%.
Over their last ten matches, Berrettini has won six and lost four, while Wawrinka has only two victories. Berrettini holds serve in 85% of games and wins 20% of return games, figures that have helped him reach the quarter-finals at the French Open. Wawrinka's first-set win rate is just 10% across his last ten, a worrying sign against a player who tends to start matches strongly.
Berrettini has spent almost ten more hours on court over his last five matches than Wawrinka, a heavy workload that might normally be a concern. However, he has been winning comfortably, and the data does not suggest fatigue has affected his efficiency. For Wawrinka, the lack of recent matches on grass and his patchy results overall leave him short of the competitive rhythm needed to trouble a player of Berrettini's calibre.
Bookmakers price Berrettini at 1.29 to win the match, with Wawrinka at 3.75. That represents a significant gap in expectation. In the first-set market, Berrettini is 1.40 and Wawrinka 3.00, reinforcing the view that the Italian should take control early.

Berrettini's serve is a major weapon, and his ability to win free points is a huge asset on grass. Wawrinka's returning numbers are low, which means he will likely struggle to create break points. Conversely, Berrettini's superior return game means he should get enough looks at the Wawrinka serve to make a difference. The Swiss veteran's only clear path lies in his experience and ability to raise his level on the big points, but the current data suggests that will not be enough.
Prediction
Matteo Berrettini
Stan Wawrinka
The data points clearly towards Matteo Berrettini. His superior season record, much stronger recent form and better returning efficiency all tilt the analysis in his favour. The betting market agrees, and Stan Wawrinka's limited grass-court preparation and poor recent win rate make an upset look unlikely.
