Sport was defined by fine margins and big stakes. In east London, Arsenal’s 1-0 win over West Ham hinged on a dramatic VAR call that wiped out Callum Wilson’s stoppage-time equaliser for a foul on David Raya, prompting Mikel Arteta to praise officials for a “brave” decision as the Gunners tightened their grip on the Premier League race. On the golf course, Alex Fitzpatrick surged to the top of the Truist Championship with a sparkling 64, taking a one-shot lead into the final round while Rory McIlroy tumbled out of contention with a ragged 75. In the NBA, Steve Kerr looks set to remain the steady hand in Golden State, agreeing in principle to a new two-year deal despite the Warriors’ disappointing finish. And in Newark, Sean Strickland reclaimed the UFC middleweight title, edging previously unbeaten Khamzat Chimaev by split decision.
