BIRMINGHAM, Ala. – Mark Calcavecchia's 8-foot closing putt for birdie put him in a better mood and sole possession of the second-round lead in the Regions Tradition at Shoal Creek.
Calcavecchia insisted that only the first benefit was meaningful.
He shot his second straight 3-under 69 on Friday to reach 6 under and take a one-stroke lead over Jay Haas at the Champions Tour major. Haas had a 70 after they came in as part of a four-way tie.
Haas missed a 4-footer on No. 18 to give Calcavecchia a shot at the solo lead at the midway point. Calcavecchia said finishing with a birdie improves his mood, lead or no lead.
''It really doesn't matter, other than the fact that I'm happier that I made the putt on the last hole, made the 8-footer for birdie as opposed to missing it,'' said Calcavecchia, who is seeking his first Champions Tour win since the 2012 Montreal Championship. ''Sixty-nine sounds better than 70, it always has.
''It always feels good to birdie the last hole. Leading as opposed to being tied for the lead, that makes no difference whatsoever to me.''
It was the highest score for a 36-hole leader at the Tradition since J.C. Snead was 6 under at Desert Mountain in 1996. The 36-hole leader has only won one of the last nine majors on the 50-and-over tour, with the exception being Mark Wiebe last year in the Senior British Open.
Calcavecchia's main concern is a rib problem he aggravated late in Thursday's round, leading to upper back spasms. He said it began flaring up again after swings starting on No. 14 Friday.
''It's like a delayed reaction, then it kind of goes away,'' he said.
Haas birdied the first four holes, and Calcavecchia had three birdies on the first six holes.
''I didn't put myself into a lot of bad positions,'' Haas said. ''Being 4 under after four was kind of a dream start and it kind of slowly got away from me. But I like my position. I feel pretty good about my situation going into the weekend.''
He bogeyed No. 5 after landing in the bunker and then three-putted No. 15 for another bogey. Haas followed that with a 35-footer for birdie on No. 16.
Calcavecchia also had a bogey on the 15th hole after having a bad lie about 10 yards right of the green. He chipped it some 15 feet past the hole.
Calcavecchia said he started his round knowing Haas had gotten off to a good start and that Tom Pernice Jr. - who finished with a 70 and was four strokes back - had also opened with four straight birdies. Beyond that, he said he's not a scoreboard watcher.
''There's no point in really looking at this stage,'' Calcavecchia said. ''You're just trying to play the course and make as many birdies as possible and pars. Still a long way to go. If it was a three-rounder like most of our regular tournaments, it would be a little different story maybe. But we're only halfway done.''
Haas takes a different approach.
''I look at scoreboards all the time,'' he said. ''I like seeing my name up there and seeing what's going on and all that. It's such a long race and there's so much golf left to be played that I'm not too concerned about one shot here and there. You hate to throw any shots away obviously, but I'm still feeling pretty good about where I am.''
Perry had three birdies on the final nine holes and was already looking forward to Round 3.
''Saturday's the rocking chair day as I call it, and I've got to make my move on that day,'' said Perry, who also had two bogeys. ''I need to shoot another one of these or a little better to get back into it for Sunday.''
