Kevin Na’s decision over the weekend to resign from the PGA Tour left many of his colleagues scratching their heads. But one of Na’s fellow tour pros – and his top Twitter rival – had a different reaction: don’t let the door hit you on the way out.

OK, so those aren’t the exact words Grayson Murray used, but it’s basically what he was thinking. He said as much with this reaction to Na’s announcement:

That’s a double dagger right there. “You won’t be missed” and “our rounds just got 20 minutes faster!” Ouch. It also should be noted that Murray, ranked 548th in the world, has played more rounds on the Korn Ferry Tour than the PGA Tour this season.

Anyway, in case you weren’t aware, these two have history. It started with Murray criticising Na’s “deliberate” pace of play with a tweet in January that caused a social-media scuffle between the two, which escalated to a profanity-laced argument on the driving range at the Mexico Open in April.

“It was a very immature thing to say four months later, and to do it on the range, which he knows is his safe spot,” Murray said in April. “He knows that I’m not going to do anything to him, he’s just provoking me.”

Of course, Murray was in full provoke mode himself with his weekend tweet. However, he did offer a follow-up that softened the blow.

Then again, if Murray really wants a LIV invite, he should probably lean into the whole feud angle.
