Parker McLachlin cruised to seven-stroke victory at the Reno-Tahoe Open on Sunday for his first career PGA Tour win.

Despite carding a final-round two-over-par 74, McLachlin finished the tournament at 18-under-par 270.

In what was pretty much a fruitless chase, Brian Davis finished a distant second after a three-over-par round on Sunday to finish 11-under for the tournament.

Playing his 52nd career PGA Tour event, McLachlin had just three top-10 finishes - although two of them came this year at the Sony Open and AT&T Classic.

The 29-year-old McLachlin put himself in great position to record his first win on Saturday when he fired a six-under 66 take a commanding six-stroke lead into the final round.

That provided him with the cushion he needed to overcome some shaky play and earn the $540,000 first-prize purse.

McLachlin played a bogey-free front nine, but bogeyed the par-four 10th hole.

He rebounded to par the next five holes before bogeying the par-three 16th and the par-five 17th.

But the five-year Tour veteran finished well with a birdie on 18 to triumph.
