Fowler, 34, had a great start to his professional career, notching five PGA Tour wins between 2012 and 2019 as one of the best players in the world.
But since his last win in February 2019, the long-time fan favourite lost his form for a few years and even struggled to qualify for the major championships.
Now, however, it appears Fowler is officially back.
The California product moved to No. 35 in the world following a tie for fifth at last week's US Open.
He had opened the tournament with a record 62 (matched by Xander Schauffele on the same day) for a share of the lead, but couldn't close it out on Sunday.
This week, Fowler is back in action for the Travelers Championship at TPC River Highlands in Connecticut.
After rounds of 70 and 65, Fowler was 10 strokes back of the leaders with a 36-hole score of 5-under par.
On Saturday, Fowler threw himself into contention for the second-straight week after nearly shooting an incredible 59.
He made eight birdies and one eagle (at the par-5 6th) to record a career-low 10-under par 60.
He had a chance for 59 on the final hole (the par-4 9th), with a 14-foot chip from the fringe for birdie that ultimately missed by 16 inches.
"Yeah, I hit a great shot; executed what I wanted to," Fowler told reporters on his chip for 59. "If I went back out in the same conditions I would've told you this is where I want to start it and it should move to the hole; it just didn't."
Good friend Justin Thomas, who shot his own impressive 62 on Saturday, was waiting for Fowler after his round.
Here's the clip:
Keegan Bradley, who was tied for the lead at 15-under heading into the weekend, shot a 64 on Saturday. He had a 1-stroke edge at 21-under par over Chez Reavie, who shot 63.
Patrick Cantlay was alone in third at 16-under par.
