First reserve Nate Lashley took full advantage of his late entry into the Rocket Mortgage Classic by shooting a career-best 63 to take the first-round lead on nine under.
The 36-year-old, ranked 353rd in the world, was first alternate at last week’s Traveler’s Championship but did not get an opening, so when the chance came at the Detroit Golf Club, he seized it after David Berganio withdrew on Wednesday.
Waterford’s Séamus Power – who will return to Ireland for the Irish Open next week – has work to do to make the cut after his opening round of 73. The lone Irishman in the field in Detroit was two under through his first nine holes before bogeying the 10th and finishing with an ugly double bogey six at the 18th.
Unheralded Lashley carded four birdies on the front nine and five on the back in a bogey-free round which put him top of the leaderboard early on and he was never caught.
Ryan Armour and Nick Watney came closest, one shot behind after rounds of 64, with a large group on seven under including former Open champion Stewart Cink.
“When you’re first alternate, it’s not a whole lot of fun, that feeling of only missing getting in the event by a spot, by one person,” said Lashley, who is playing this season on conditional status after earning his PGA Tour card in 2018.
Newly crowned US Open champion Gary Woodland recovered from being five over through 11 holes to finish with four birdies in his last six to shoot a one-over 73.
