Pieters started on the 10th tee and went out in 40 shots after playing holes 16 to 18 in 4-over par.
Understandably frustrated as he turned to the 1st tee, Pieters reached boiling point when sending his tee shot clattering into the trees down the left flank and through onto the adjacent 9th fairway.
As Pieters trudged off the tee box, he sent his Titleist TSi 2 Driver into a nearby trash can.

Thomas Pieters threw his driver into a trash can after pull-hooking his drive left on his 10th hole of the day.
Used 3-wood for the remaining 6 non par-3 tee shots, hit every fairway and made all pars.
Pieters has been known to have something of a fiery temper down the years.
He threw his toys out the pram last season, but it was nothing compared to this beauty from the BMW PGA Championship at Wentworth back in the day:

Golf Digest's Luke Kerr Dineen was the first to confirm the news of Pieters sending his driver into the trash on Twitter:
"In non-Jon Rahm news.... Thomas Pieters threw his driver into a trash can after pull-hooking his drive left on his 10th hole of the day. Used 3-wood for the remaining 6 non par-3 tee shots, hit every fairway and made all pars."
According to Golf Digest, Pieters said:
Pieters went on to bogey the par-4 1st and he would par his way into the clubhouse for a round of 5-over 77.
That left him in a tie for 48th on 8-over par for the tournament.
Apparently Pieters had been "courted by LIV Golf officials for months", according to a report in The Telegraph.
It is said that Pieters accepted a $10m fee to join the Saudi-bankrolled circuit.
Apparently a position to join Bubba Watson's RangeGoats team became available after Hudson Swafford picked up an injury ruling him out for much of the season.
Pieters told Golf Digest's Evin Priest:
He has managed Woods since 1998.
Pieters was recently announced as one of six new LIV Golf signings ahead of their first tournament of the new season in February.
