Purdy slips to second place

— -- SAN ANTONIO -- Dean Wilson shot a 5-under 65 on Friday and led first-round leader Ted Purdy by a stroke halfway through the Texas Open. Wilson was at 11-under 129 after 36 holes at the La Cantera Golf Club course in the rocky hills just north of San Antonio. David Peoples (64), Ryan Palmer (65), John Senden (65) and J.J. Henry (67) were all at 131, one shot ahead of Scott Simpson (67) and Aaron Barber (63). Barber's round was the lowest of the day. Two-time champions Duffy Waldorf (67) and Justin Leonard (68) were in a group of four at 133. Jesper Parnevik (65) and past winners Bob Estes (66) and Loren Roberts (68) were in a group of 10 players at 134. High temperatures, which reached 97 degrees, and high humidity again took their toll on the players starting their rounds later in the day. Wilson, who went out early in the morning, opened his round with a birdie at No. 1, the event's longest hole at 665 yards. On the back nine, he had birdies on three of the first four holes before recording his only bogey, a three-putt on the par-4 15th. He got the stroke back on 18 when he hit a 7-iron within 3 feet for a birdie. Purdy, whose 61 on Thursday matched the course record, was among the last players to tee off and had to contend with the stifling afternoon heat. He had his first bogey of the tournament on the par-4 4th, and had two more by the turn to drop two strokes behind Wilson. Purdy (69) recovered with two birdies early on the back nine, but he bogeyed the par-3 17th after hitting his tee shot over the green and later two-putting from 15 feet. Henry, who began the day tied for second with Wilson and Tim Clark, turned in a steady round of 67. His only bogey came when he missed a 6-foot par putt on the par-3 2nd. His only birdie on the back nine was on the 14th, a short par-5.
