Doug Tewell, who started the day tied for 10th, shot six-under-par 65 today to overtake crowd favorite Lee Trevino and move into a one-stroke lead after three rounds of the $400,000 Houston Coca-Cola Open.

Tewell, winless on the PGA Tour for three years, was five shots behind Trevino at the start of the third round but played an almost flawless round. He had seven birdies and only one bogey for the lowest 18-hole score of the tournament.

Trevino, easily drawing the biggest gallery, lost the lead for good at No. 15 with his second bogey of the day. Tewell made birdie putts on 15, 16 and 17 to go seven under par for the tournament with a 206 three-round total. He shot 69 and 72 in the first two rounds.

Trevino, trying to win his first tournament in two years, finished with 71 for a 207 total and second place.

"My putter got even with me today," said Trevino. "My putter said, 'Hell with you. I worked for you Thursday when you didn't feel good. I'm not carrying you any more.' "

Trevino said he was fatigued because he is out of shape after splitting his time between golf and doing commentary for NBC this year.

John Cook, who started the day at 140, shot 68 for a 208 and third place.
