Golf: Brendon Todd leads by 2 at Nelson; Paul Casey has record back 9

Irving, Texas • Paul Casey was scuffling midway through his second round at the Byron Nelson Championship, hoping he could do enough just to make the cut.

After a record back nine, Casey was near the top of a crowded leaderboard. He was in a group of eight players at 6-under 134, two strokes behind leader Brendon Todd.

Casey was over par Friday before matching the PGA Tour record for the best score on a back nine, an 8-under 27 with six birdies and an eagle. That was part of his 7-under 63 that was the low round of the day, though he could never remember such a good nine.

"On par-3 courses, I think," Casey said. "I like to think I would be good at shooting low rounds of golf through the past, but certainly nothing like that."

When Casey made the turn, he was coming off a three-putt at No. 9, his third bogey of the day. The 36-year-old Englishman, whose only PGA Tour victory was five years ago, was then 2 over for the tournament, even after making a 9-foot eagle putt on the par-5 seventh hole.

"I think it's easier when your back is up against the wall, like I was today" Casey said.

In Birmingham, Ala., Mark Calcavecchia made an 8-foot birdie putt on the final hole to take a one-stroke lead over Jay Haas after the second round of the Regions Tradition.

Calcavecchia shot his second straight 3-under 69 to reach 6 under, while Haas had a 70 at the Champions Tour major.
