Looking to build on his win at last week's Canadian Open, Rory McIlroy jumped out to the early lead in Thursday's first round of the U.S. Open at The Country Club in Brookline, Massachusetts.

However, Canadian Adam Hadwin came through in the afternoon to shoot a 4-under-par 66 to pace the field, one shot better than a group of five golfers -- McIlroy, MJ Daffue, Joel Dahmen, Callum Tarren and David Lingmerth.

Jon Rahm, who won the tournament last year at Torrey Pines in San Diego to become the first U.S. Open champion from Spain, carded a 1-under 69. 

Phil Mickelson -- who has six major titles, but has never won the U.S. Open -- shot an 8-over 78.
