FLOURTOWN, Pa. — Keith Mitchell held the first-round lead at three tournaments earlier this season before falling out of the top spot. He’s showing staying power at the Truist Championship.

Mitchell followed a career-best round with a 3-under 67 on Friday and maintained a one-shot lead after two rounds at Philadelphia Cricket Club’s Wissahickon Course.

Mitchell, who led the way with a 61 on Thursday, offset two bogeys with five birdies, including a three-hole run on Nos. 3-5, for a 12 under total.

Shane Lowry was second at 11 under after a 5-under 65, and Sepp Straka (67) was another stroke back. Defending champion Rory McIlroy shot a 3-under 67 and was tied in a large group for fourth.

Mitchell said he’s feeling more comfortable in the top spot. And it showed.

One day after 64 of the 72 golfers in the no-cut field broke par in near-perfect weather and scoring conditions, the course was softened by overnight rain and the field dealt with on-and-off showers and temperatures in the 50s Friday. The result: longer irons into Philly Cricket’s modest par 4s and a more difficult 7,100-yard, par-70 test for the sixth signature event of the PGA Tour season.

Lowry was undeterred by the weather and posted the lowest round of the day, while McIlroy was joined at 7 under by Justin Thomas (67), Colin Morikawa (70) and Patrick Cantlay (68), among others.

Mitchell was steady throughout, never wavering from his preplanned strategy on the A.W. Tillinghast design that opened in 1922. He followed bogeys at Nos. 2 and 11 with birdies and described the bounce-backs as “huge.”
