Poulter tweeted late Friday night that Matsuyama, “buried his putter in the 13th green 5 feet from the hole. (A) referee had to repair the crater. Because he didn’t.”
Poulter continued: “Why should Matsuyama leave a crater in the green for others to putt over, or have to call a referee to repair the damage. Idiot.”
And finally, “I’m no saint and first to say, but that was disgusting. I wouldn’t bury a putter in a green 5 feet from a hole and have players behind deal with it.”
Poulter played in a threesome that was one group behind Matsuyama for the first two days of the WGC-Cadillac Championship.
Neither player was immediately available for comment.
Update: According to the AP's Doug Ferguson, Matsuyama apologized to Poulter on the driving range Saturday morning. Golfweek's Alex Miceli snapped a photo of the meeting:
