The Northern Irishman has had well documented issues with his swing in recent weeks and has linked up with renowned coach Pete Cowen for the tournament at the Austin Country Club.

But McIlroy struggled badly during his round-robin opener against fellow Europe Ryder Cup star Poulter and was already two down by the time he pulled his tee shot wildly left at the fifth tee, with his ball sinking into the pool at a nearby house.

He managed to claw within one by the eighth, but Poulter then won five holes in a row to condemn McIlroy to a heavily opening defeat in Group 11, where Cameron Smith beat Lanto Griffin in the pool's other opener.

Dustin Johnson had no such woe as he started with a 2 Up win over Adam Long in Group One, while Jon Rahm defeated Sebastian Munoz 1 Up (Group 3), but Bryson DeChambeau was beaten by Antoine Rozner 2 Up (Group 5).

Justin Thomas was beaten 3 and 2 by Matt Kuchar (Group 2), though, while Jordan Spieth outclassed Matthew Fitzpatrick 3 and 1 (Group 15) despite a comedy moment when he drove the 15th green…but from the 13th tee.
