Robert Streb fired a 7-under 64 on Sunday to run away with the title at the Mylan Classic, beating the field by 4 shots for his first Web.com Tour victory.
Streb finished the tournament at 18-under par 266, beating the tournament record set by Gary Christian last year by one stroke. It was plenty of cushion, too, as nobody could keep pace with Streb on Sunday.
The tour rookie had finished in the top ten four times already this season, and his performance this week allowed him to earn the breakout win.
Matt Weibring (67), Brad Fritsch (68) and Cliff Kresge (69) shared second place at minus-14. Ben Kohles, who won his first two starts on tour this season, carded a 67 and finished fifth at 13-under 271.
Kresge began the round with a 1-shot advantage over Streb, Fritsch and Thompson.
Thompson and Fritsch were largely non-factors Sunday. Thompson parred 10 in a row before making his first birdie, and never put together a big run. Fritsch, meanwhile, turned in a bogey-free round but had only one birdie through his first 14 holes.
By that time, Streb was well in front. He birdied the first hole to match Kresge, who answered with a birdie at the third. The two -- who were playing in a threesome along with Thompson -- continued to battle.
Streb birdied the fourth before Kresge gained another stroke at the fifth to pull ahead again. Streb followed a birdie at the sixth with a bogey at the seventh, but closed his front nine by rolling in back-to-back birdie chances.
That put him at minus-15, while Kresge was sitting two shots behind after stumbling to a bogey at No. 8. He appeared to threaten Streb's hold on first place with birdies at 10 and 11, but lost those gains with two bogeys in his next five holes.
Streb continued to play well. He rolled in birdies at 11 and 14 to get to 17- under, then punctuated his round with another at 16, at which point his win was all but assured. He parred his final two holes to wrap up the title.
Thompson finished with a 1-under 70 and took sixth at minus-12. Justin Hicks (65), Will MacKenzie (67), Dawie van der Walt (68), John Chin (68) and Kevin Kisner (70) tied for seventh at 11-under.
NOTES: Streb earned $108,000 for the victory...The Web.com Tour has off next week before resuming September 13 with the start of the Boise Open. Jason Kokrak was last year's winner.
