Rahm (66) is the leader in the Dell

Jon Rahm accomplished so much so quickly that he began to wonder what else was left for him to achieve in his first full year on the PGA Tour.

Now the 22-year-old Spaniard 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 an eagle and five birdies over his last 10 holes for a five-under 66 and a twoshot lead at the halfway point of the Dell Technologies Championship in Norton, Mass.

He made a 12-foot eagle putt on the par-five 18th and then shot 31 on the front nine to reach nineunder 133. No one could catch him in the afternoon, least of all Dustin Johnson.

Johnson, the world’s No. 1 player who had a oneshot lead going into the second round, had two double bogeys after a quick start and needed a birdie on the 18th hole to keep from falling further behind. Johnson shot a 72 and was five shots behind. Paul Casey (65) was two shots off the lead along

with Adam Hadwin (65), Kevin Streelman (65) and Kyle Stanley (68). Lucas Glover and Grayson Murray each made a hole in one that the PGA Tour estimated were 65 seconds apart. Phil Mickelson dropped only one shot on his way to a 67. He was just three shots off the lead at six-under 136, his best 36-hole score since the FedEx St. Jude Classic in June. Jordan Spieth also turned around his fortunes. Despite missing two birdies inside seven feet, Spieth still shot a 65 and was in the group four shots behind.

Rory McIlroy missed the cut as the defending champion for only the second time in his career.

Stacy Lewis took a three-stroke lead in the Cambia 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 to the relief efforts. The 11-time LPGA Tour champion also is trying to win for the first time since June 2014.

“It would be probably one of my most special wins, just to be able to do this for the people in Texas,” Lewis said.

Tied for the second-round lead with two-time defending champion Brooke Henderson and In Gee

Chun, Lewis had eight birdies — five on the front nine — in a seven-under 65 Saturday at tree-lined Columbia Edgewater. She had a 17-under 199 total after opening with rounds of 70 and 64.

Moriya Jutanugarn was second after a 66. Chun was another stroke back after a 69.

Henderson had a 74 to drop into a tie for 13th at eight under. Ai Miyazato also was eight under after a 72. Scott McCarron eagled the par-five 18th hole for a six-under 64 and a two-day total of 13-under 127 and a two-stroke lead in the PGA Tour Champions’ Shaw Charity Classic in Calgary, Canada. First-round leader Kevin Sutherland was tied for second with Miguel Angel Jimenez. Sutherland followed his opening 62 with a 67, and Jimenez shot 65. Scott Dunlap and Todd Hamilton were three strokes back at 10 under after 66s. Nick Faldo had a 64 to join Jerry Kelly and Bob Estes at nine under. Kelly and Estes each shot 65.
