Notes Injured McIlroy to skip BMW

Spieth out at Nelson; Kokrak leads by 5

Jason Kokrak shot a bogey-free 8-under 62 Friday for a record five-stroke lead after two rounds at the AT&T Byron Nelson at Irving, Texas, where local favorite Jordan Spieth missed the cut for the first time at the tournament where he made his debut as a 16-year-old high school junior.

Kokrak, the 128th-ranked player in the world, matched the Nelson's 36-hole record at 12 under after his career-best scoring round, and no one has ever had a bigger lead there after two rounds.

Billy Horschel was second at 7 under after three consecutive birdies to finish a 65. Dustin Johnson, the world's No. 1 player, had his second consecutive 67 and was among six players tied for third.

Spieth closed with a 75, including a 9 on the par-5 16th after hitting two tee balls out of bounds. With a 3-over total and needing at least one birdie, Spieth finished with consecutive pars. His 17-foot birdie try at No. 17 curled by the cup, and he missed a 14-footer on 18.

The 23-year-old Spieth also missed the cut last week in The Players Championship. He last missed consecutive cuts in 2015.

Thompson opens 3-stroke lead

Lexi Thompson shot her second straight 6-under 65 to take a three-stroke over playing partner Gerina Piller into the weekend at the Kingsmill Championship at Williamsburg, Va. Thompson is playing her third tournament since losing the ANA Inspiration in a playoff after being penalized four strokes for a rules violation that a TV viewer spotted. The long-hitting Florida player had six birdies in a bogey-free round on Kingsmill's River Course. She waited out an hour rain delay in the middle of the round. Rory McIlroy will sit out the European Tour flagship event next week to make sure a recurring rib injury heals. McIlroy withdrew Friday from the BMW PGA Championship at Wentworth, where he is a past champion. The four-time major champion suffered a hairline fracture of his rib during the South African Open in January, causing him to miss four tournaments over seven weeks. He played four times in six weeks upon his return until taking a post-Masters break to get married. McIlroy believes the injury surfaced again from long practice sessions leading to The Players Championship. McIlroy says doctors have advised him to take a conservative approach to recovering so he will be fine for the U.S. Open and the rest of the majors this summer.
