Fresh off his fifth ATP victory in San Diego, the Norwegian has won the most titles of any player in 2021.

The ranking points from eight ATP events and four WTA events, as well as 2020 Roland Garros points for the women if they’re still on there, will all be dropping off.

He won his first trophy on hard courts in dominant fashion over Cameron Norrie.

The Norwegian had previously won tournaments in Geneva, Bastad, Gstaad and Kitzbuhel.

Ruud edged former No. 3 Grigor Dimitrov while Norrie took out current No. 5 Andrey Rublev.

Andy Murray’s bid to reach quarterfinals in consecutive weeks has ended with a mistake-filled 7-5, 6-4 loss to No. 2 seed Casper Ruud at the San Diego Open

John Isner and Denis Shapovalov made it 3-1 after Day 1 with a late night doubles win over Matteo Berrettini and Alexander Zverev.

In a match-up of event newcomers, Team Europe's Ruud defeated Team World's Opelka, 6-3, 7-6 (4), on Friday afternoon at TD Garden.

Without the guidance of Roger Federer, Rafael Nadal and Novak Djokovic, this could be the time for Team World in front of a rowdy Boston crowd.

Andrey Rublev, Casper Ruud and Coco Gauff also made major noise on the rankings this week.
