WATCH: Darren Clarke FLIPS at official as caddie removes a BIRDHOUSE!

Darren Clarke received a two-stroke penalty during his US Senior Open debut on Thursday after his caddie attempted to remove a BIRDHOUSE in his player's line - and the former Open champion was FUMING!

Clarke made the turn at 1-under par but then sailed his tee shot way left into trouble at the 10th hole with his ball nestling in the fescue by the woods. 

While in conversation with a rules official, Clarke's caddie attempted to remove a birdhouse that was in the Northern Irishman's line to the pin, which according to the rulebook, IS allowed under USGA Rule 15.2 on movable obstruction.

The only issue, however, is that althought the birdhouse might have been movable, it was technically immovable!

Under the USGA rules, a birdhouse is considered an immovable obstruction because it is a permanent fixture on the course. Under Rule 16-1, a player only receives relief when a) the player’s ball touches or is in or on an abnormal course condition b) abnormal course condition physically interferes with the player’s area of intended stance or area of intended swing c) or only when the ball is on the putting green, an abnormal course condition on or off the putting green intervenes on the line of play.

So in short, there was no relief for a birdhouse in line of sight.

Clarke was not informed of his two-stroke penalty until later in the round, and he was understandably angry by the decision as his bogey changed to a triple bogey.

He ended up finishing the day on 3-over par and 11 strokes off the pace.
