Rory McIlroy made no apologies for showing flashes of frustration even as he made an excellent start to his bid for a fifth major title in the 122nd US Open.

McIlroy carded a three-under-par 67 at Brookline to share second place with England’s Callum Tarren, David Lingmerth, Joel Dahmen and MJ Daffue, a shot behind Canada’s Adam Hadwin.
