Phil Mickelson knows how to get under Tiger Woods’ skin.

As the golfer detailed in HBO’s “24/7” special, which aired Tuesday night, ahead of the duo’s highly anticipated match in Las Vegas on Nov. 23, he once used a dinner to irk his rival during 2012’s Pebble Beach National Pro-Am, in which Woods was paired with then-Cowboys quarterback Tony Romo.

“His partner that week was Tony Romo, and that night before the final round was a big dinner that Jim Nantz put on, and I got seated next to Tony,” Mickelson explained.

“We had this great night, had a lot of fun. But I knew that it would bother Tiger that I had dinner with his partner. Tony knew this would also bother him, too, so he said to his caddie … ‘Just don’t mention that we had dinner last night,'” he continued.

Once they hit the course, Mickelson plotted the right moment to distract Woods.

“We’re on the first tee, I tee off, Tiger tees off, and I wait before I walk off because I want a distance between me and Tony so I could say it loud enough,” he explained.

“As we’re walking off the first tee, I yell out, ‘Hey, Tony, that was so much fun last night. I loved the dinner,'” Mickelson continued, adding Woods looked right at Romo, who said: “There were a lot of people there. It was a random seating.”

Mickelson’s words may have gotten to Woods, given he shot a 75 at the tournament.
