Shane Lowry took to Twitter to show off his threads ahead of the first round of the US Open - and Boston Celtics fans will be impressed by the Clara man's choice.
Posting a tweet to his official Twitter page, the photo displayed a crisp white polo shirt with a large Boston Celtics logo emblazoned on the back.
It is a savvy move from the Co. Offaly golfer given that this weekend's US Open will take place at The Country Club at Brookline, a course not too far outside of Boston, Massachussets.
The Celtics' official logo since the 1960's has been a depiction of a leprechaun spinning a basketball, but shamrocks also hold a close association with the NBA team.

The emblem adorning Lowry's shirt is the Celtics' secondary logo, which is used at present on player and fan apparel.
