The Clara man tees off alongside Phil Mickelson and Louis Oosthuizen.
Shane Lowry is one of the late starters on day one of the US Open - the third major of the year.
The Clara man tees off just before 7pm Irish time at Brookline in Boston in an interesting group featuring LIV rebels Phil Mickelson and Louis Oosthuizen.
Lowry has reestablished his loyalty to the PGA and DP World Tours, and says he won't be joining LIV golf.
However, he's confident that playing with Mickelson won't be off putting:
Rory McIlroy is one of the early starters on day one, teeing off at 12.40pm Irish time.
Seamus Power tees off at 6.25pm this evening.
