RENO (AFP) - Scott Piercy dropped a three-stroke lead but held on and made a seven-foot par putt on the final hole to win the US PGA Tour's Reno-Tahoe Open by one stroke on Sunday. Piercy carded a final-round two-under par 70 for a 15-under total of 273 and a one-stroke victory over Pat Perez. Piercy claimed his first US PGA Tour title and insured his stellar 11-under 61 in Saturday's third round wasn't wasted. Piercy led by three strokes through 11 holes. But after Perez birdied the par-four 12th and par-five 13th, Piercy bogeyed the 365-yard par-four 14th. He had tried to drive to the green but his ball hit a cart path and rocketed 30 yards left. Perez was tied for the lead with two holes remaining but fell back with a bogey at the 17th where he missed an eight-foot par putt. Piercy's worries weren't over. Arriving at the final hole with a one-shot lead he belted his drive 387 yards but it ran to the left and into desert scrub.
