WATCH - Graeme McDowell hilariously pranks Shane Lowry on Royal Troon putting green
Close pals Graeme McDowell and Shane Lowry are always game for a laugh and the Northern Irishman definitely has the upper hand at Royal Troon this week.
The duo were practising together at the Scottish venue earlier this week and we just hope there wasn't money on the line.
Lowry is known for having little wagers on the course but hopefully he makes an exception when playing alongside G-Mac.
McDowell sabotaged a Lowry putt in quite spectacular fashion. Watch below:
What a throw!
