Canada's Taylor Pendrith claims share of lead at Rocket Mortgage Classic

Tony Finau sent an approach from 250 yards soaring over trees and onto the seventh green at Detroit Golf Club, going for the reward and ignoring the risk with a difficult shot.

Finau, coming off his third career victory on the PGA Tour, and Canadian Taylor Pendrith shared the first-round lead at 8-under 64 on Thursday in the Rocket Mortgage Classic.

The pivotal shot on Finau's 16th hole, a 560-yard par 5, set up a two-putt from 43 feet for one of his eight birdies.

"I had to get all of it to get it to the hole and hit it right in the middle of the green," he said.

The leaderboard was filled with players who took advantage of favourable scoring conditions with morning tee times. In the afternoon, the wind picked up and the scores did as well.

Former U.S. Open champion Webb Simpson, Michael Thompson, Cameron Champ, Lee Hodges and Matt Wallace were two shots back.

After cooling off with four straight pars, Finau closed with his seventh and eighth birdies in a bogey-free round. He hit all 18 greens in regulation for the first time in 728 PGA Tour stroke-play rounds.

On the par-4 eighth hole, he made a 41-foot putt downhill with a slight break from right to left for another birdie and a three-shot lead.

"It was nice to just get a bonus birdie on 8 after a poor wedge shot, but that's why we call our putter the equalizer," Finau said.

Pendrith, a 31-year-old PGA Tour rookie, surged into a
