Reed had a disappointing round on Friday, and just avoided beating the cut at Pebble Beach.
On the par-5 18th hole, he struggled and was forced to putt in for a double-bogey.
The American started the hole badly, as he drove a 280-yard shot wide into the right-hand-side.
From there, he hit a follow-up shot straight into the bunker on the left of the fairway.
To try and get out of the bunker, he chipped out well, but the ball soared over the green.
In an attempt to save par, he lobbed back onto the green, but his ball rolled into the rough.
On his fifth shot, Reed was still unable to get back onto the green and barely moved his ball at all.
It was at twos point that he showed his frustrations, and snapped his wedge over his leg.
He threw both pieces of his club onto the ground in anger and immediately grabbed another from his bag.
The 28-year-old finished the hole, scoring a double-bogey, as he finished off the round two-over-par.
After footage emerged of the club snap, fans immediately took to Twitter to criticise the American’s actions.
“Kick him off the tour,” one fan wrote.
Another posted: “Disgraceful behaviour.”
“He’s so unprofessional,” one fan fumed.
One simply wrote: “What an embarrassment.”
