DETROIT -- Nate Lashley, in just his 33rd career start on the PGA Tour, capped a wire-to-wire performance on Sunday, June 30, with a 2-under 70 to finish at 25-under 263 and win the inaugural Rocket Mortgage Classic at Detroit Golf Club, his first Tour victory.

Lashley took home the $1.314 million winner's check, locked up his Tour card for at least then next two years and secured a spot on the British Open at Royal Portrush in three weeks.

"It was surreal, to be honest with you," Lashley said of his walk up the 18th hole. "I didn't know what to think. There was a lot going through my mind. It's just an unreal feeling. Just so happy to be here and happy to be in Detroit, and I'll always remember this place. Going to be a special place to me."

Doc Redman, the 2017 U.S. Amateur champion, shot a 5-under 67 in the final round to finish six back of Lashley. The winner of Monday's open qualifier, Redman was playing in just his second PGA Tour event of the season and locked up a spot in the British Open in three weeks while securing his Tour exemption for the rest of the season.

"I knew what was at stake, but I was trying not to think about it," Redman said. "I actually didn't even think about The Open Championship until someone said it to me after. ... I actually just learned that not long after I got off the course. I didn't even think about that, but I can't wait.

"I've never been over there, it's going to be an awesome experience and, you know, I can't wait to see how it is."

Slovakia's Rory Sabbatini and Wes Roach were another shot back at 18 under, while six players finished at 17 under, including 2018 Masters champion Patrick Reed and 2012 FedEx Cup champion Brandt Snedeker.

Lashley's final round wasn't nearly as sizzling as his first three, as he fired bogey-free rounds of 63 on Thursday and Saturday, sandwiching a 67 in the second round. But considering he entered Sunday with a six-shot lead, Lashley essentially just had to avoid a blowup.

He did so with two birdies and two bogeys on the front nine before cruising home for the victory.

Lashley was the last man in the field, getting in as the third alternate after a withdrawal from David Berganio on Wednesday. He became the first alternate to win a Tour event since Vaughn Taylor at the AT&T Pebble Beach Pro-Am in 2016.

"One week can change -- it's a career-changing event getting a win out here," Lashley said. "It gives you job security, it gets you into majors, you have two more years to basically get more comfortable and play better golf. So you really can't put into words how much this means, and it's just huge for my career."
