Robert Streb and Edward Loar both fired 7- under 64s on Thursday to grab a share of the lead after the first round of the Mylan Classic.

Streb, who has four top-10s this season, is still searching for his first Web.com Tour win, while Loar won the Panama Claro Championship earlier this year and is playing his sixth tour event of the year. Loar has made the cut in just four of his 19 PGA Tour starts this season.

Casey Wittenberg, who is second on the tour's money list, carded a 6-under 65. He was joined in third place by Marc Turnesa and David Lingmerth.

Former PGA Tour players Cliff Kresge and Will MacKenzie posted 5-under 66s. They share sixth place with Brad Fritsch, Kevin Kisner, Brian Stuard and John Chin.

Streb was in the last group of the morning wave and he birdied the 10th and 12th at Southpointe Golf Club to open his round. After four straight pars, Streb birdied the 17th to move to 3-under.

Around the turn, Streb stumbled to a bogey on the first. He erased that mistake with a birdie on No. 2.

Streb parred his next two holes before catching fire. The 25-year-old poured in four straight birdie efforts from the fifth to jump to 7-under. He parred the last to share the lead with Loar.

"You have to pay attention to what your wedges are doing out here. You can spin some off the greens if you're not careful. You hit a few good ones and the confidence gets going before you know it," Streb said.

Loar faltered to a bogey on No. 10, his first hole. He fought back with birdies on the 11th and 13th. Loar got to 2-under with a birdie on the 15th, but he tripped to another bogey at the 18th.

Around the turn, Loar holed a pitching wedge shot for eagle on the short par-4 second to move to minus-3. After a pair of pars, he drained three consecutive birdies from the fifth. Load connected on a birdie try on the ninth to share the first-round lead.

"I think the key out here is getting the ball in the fairway. I had a lot of wedge shots and you can attack from the fairway," Loar stated. "
