PGA Tour star Bryson DeChambeau just carded a 10 -- YES, A TEN!!! -- on a Par-5 15th hole at the Memorial Tournament in Ohio on Friday ... and it's one of the worst holes EVER by a pro!!!
The entire hole -- from start to finish -- took Bryson 26 minutes to complete ... with 4 commercial breaks!!!
Things were bad right from the jump ... DeChambeau shanked his tee shot off some trees down the left-hand side of the fairway and was forced to take a drop.
He tried to make up ground by pulling out a 3-wood and swinging for the fences .
