"I knew I was swinging well", Johnson said after his round.
DES MOINES, Iowa - Tom Lehman shot a 7-under 65 to take a two-shot lead into the final round of the PGA Tour Champions' Principal Charity Classic.
Johnson, 33, now ousts Justin Thomas and moves back to World No.1 after collecting his second win on the season and 18th career PGA Tour title. "If I play really good golf, I'm probably going to win".
"The difficulty is the rough, it's hard to get the ball on the green if you don't drive it in the fairway", Mickelson said after his round.
It appears on paper as a one-sided battle but tournament golf works in unusual ways and Putnam is an emerging star with two victories on the Web.Com Tour prior to graduation to the bigger stage this year.
Phil Mickelson plays in the second round during the second round of the St. Jude Classic golf tournament at TPC Southwind on Friday, June 8, 2018, in Memphis, Tenn. Snedeker turned in a bogey-free round with eight birdies needing only 22 putts. Johnson rolled in a 4-footer for par and a two-stroke lead at 15 under on a sizzling day with the temperature feeling like 99. Even with the 3-wood, Johnson had the second-longest drive of the day, hitting 333 yards on the 554-yard hole. Johnson tapped in for birdie, followed with a two-putt birdie at the par-5 third and added birdies at Nos. He had four of his seven birdies and an eagle on his back nine for a 29 and finished with a 10-under 130 total.
Johnson hit an iron 307 yards off the tee at No. 10.
Mickelson was up-and-down all day, opening with birdie-bogey-birdie and sneaking in a par at No. 4 before a bogey-birdie-bogey sequence brought him back to even on the day. Johnson's tee shot found the trees right of the fairway, and he threaded a shot through a couple trees to just off the green. More importantly, he would head to Shinnecock Hills with a spring in his step for the second major championship of the year. Johnson has won nine times when having at least a share of the 54-hole lead.
