Golf: Leonard looks for second Texas Open title

Justin Leonard, back in his home state, carded a seven-under-par 64 to build a three-shot lead in his quest for a second straight Texas Open title.

Leonard had 10 birdies and three bogeys on what he called ‘‘an interesting day’’ at the LaCantera Golf Course in San Antonio to reach 13-under-par on 129 at the halfway stage.

First-round leader Marco Dawson, who needs to finish in the top three to keep his PGA Tour card, is tied for second with Carl Paulson at 10-under on 132.

Jesper Parnevik of Sweden, who was due to be playing in the Ryder Cup this weekend, is tied for fourth with Jay Williamson and Tripp Isenhour on 133.

It was the fourth straight round of 65 or better at LaCantera for Leonard, who has finished no worse than second in three of his last four trips to this course.

‘‘I had 15 great holes and three others,’’ said Leonard, who bogeyed the 12th, 15th and second. ‘‘I played well the second nine,’’ he said.
