SCOTTSDALE, Ariz. — Jay Haas birdied four of the last six holes Friday for an 8-under 62 and a four-stroke lead in the Champions Tour’s season-ending Charles Schwab Cup Championship.

“I thought much harder today than yesterday,” said the 60-year-old Haas, the oldest player in field limited to the top 30 players on the money list. “The wind was difficult, the greens are still very firm. I honestly said if somebody was giving me even par before I played, I would have said, `OK, that sounds pretty good, I’ll take that.’ But I played extremely well.”

Haas had his 38th straight round of par or better to break Loren Roberts’ tour record.

“It was a pretty error-free round,” Haas said. “Disappointed that I didn’t birdie at least the last hole or at least get kind of an opportunity to shoot my age today, but it was a special round. Hit a lot of good shots and didn’t make a lot of long putts. They were all, you know, 15 feet and in probably for birdie. So it was solid golf today. I don’t know what got into me, but it was a lot of fun.”

Haas won two weeks ago in North Carolina to become the 18th player to win a Champions Tour event at 60 or older.

He has 17 victories on the 50-and-over tour after winning nine times on the PGA Tour.

Haas had a 12-under 128 total on Desert Mountain’s Cochise Course.

“I played pretty well,” Pernice said. “The conditions were obviously a little more difficult with a little bit more breeze blowing today, so it was a little bit trickier. I struggled a little bit on the speed of the greens, I left several putts short.”
