The week of shirtless golfers continues.
Mickelson appears content with missing the Tour Championship, as he sits poolside sipping on an expensive bottle of wine.
Players competing in the Tour Championship commented on Mickelson's post during the second-round delay at East Lake Golf Club.
"Not the best year for Bordeaux ... and you have to breathe to taste it anyway 😂🍷," Rory McIlroy commented.
The aforementioned Koepka wondered why Mickelson didn't go all out like he did: "What's with all those clothes?"
Earlier this week, Tina Mickelson, Phil's sister, posted a picture of Lefty spending time at the beach.
While Mickelson's game on the course may not be sharp, his antics on social media are always entertaining.
