NORTON, Mass. — Jon Rahm accomplished so much so quickly that he began to wonder what was left for him to achieve in his first full year on the PGA Tour.
He now has 10 million reasons to play his best golf.
Already very much in the hunt for the FedEx Cup and its $10 million bonus, Rahm took another step Saturday when he made eagle and five birdies over his last 10 holes for 5-under 66 and a two-shot lead at the halfway point of the Dell Technologies Championship.
Rahm already has a short history of strong finishes in his first trip to the TPC Boston.
One day after he birdied four of his last five holes, he made a 12-foot eagle putt on the par-5 18th then shot 31 on the front nine to reach 9-under 133.
No one could catch him in the afternoon, least of all Dustin Johnson.
Johnson, the world's No. 1 player who had a one-shot lead going into the second round, had two double bogeys after a quick start and needed birdie on the 18th hole to keep from falling further behind. Johnson shot 72 and was five shots back.
It has already been an amazing year for Rahm, 22. He was No. 137 at the start of the year. Now he's at No. 5. His main goals were to get to East Lake for the Tour Championship and win a tournament.
But after a runner-up at Colonial, he has missed the cut twice and finished out of the top 25 in three other PGA Tour starts.
"It's probably because I got to the point where I had accomplished so much more than I had set myself to in the beginning of the year that I felt like there was nothing else to do," he said. "It made me complacent of what I had accomplished all year. I didn't play with the same intensity. I really didn't have a goal.
"It's taken me two months to realize what I've done, and hopefully I can keep surprising myself."
Paul Casey, who played in the final group last year, had 65 and was two shots back along with Adam Hadwin (65), Kevin Streelman (65) and Kyle Stanley (68).
LPGA: Stacy Lewis took a three-stroke lead in the Portland Classic in Oregon in her bid make a big donation to hurricane relief in her hometown and end a long winless streak. From the Woodlands in the Houston area, Lewis has pledged to give her earnings — first place is worth $195,000 — to the relief efforts. Tied for the second-round lead with two-time defending champion Brooke Henderson and In Gee Chun, Lewis had eight birdies in a 7-under 65 to reach 17-under 199. Moriya Jutanugarn was second after 66. Chun was another stroke back after 69. Henderson had 74 to drop into a tie for 13th at 8 under.
CHAMPIONS: Scott McCarron eagled the par-5 18th for 6-under 64 and a two-stroke lead in the Shaw Charity Classic in Calgary, Alberta. McCarron was at 13-under 127 overall. First-round leader Kevin Sutherland, McCarron's childhood rival in Sacramento, Calif., was tied for second with Miguel Angel Jimenez. Sutherland followed his opening 62 with 67, and Jimenez shot 65.
