Tom Lehman found a litany of things not to like about the way he played in the Regions Tradition.

"I didn't ever really have a good rhythm with my swing," he said.

And, "I hit a number of bad tee shots."

Not to mention, "I didn't putt well all week."

By the way, Lehman won the Champions Tour's first major and gained his third victory in seven events this year. He kept his few mistakes and imperfections from being costly and beat Peter Senior with a par on the second hole of a playoff Sunday.

Senior, from Australia, missed a 5-foot par putt when it lipped out on No. 18. Lehman two-putted from about 20 feet, polishing off his second bogey-free day at the first Champions Tour major of the season.

"It's unfortunate to win when somebody misses," Lehman said. "I wish I could have made a birdie. That would have been more fitting."

Both parred the first playoff hole, also No. 18 at Shoal Creek.

Lehman and Senior finished at 13-under 275. Lehman had a 3-under 69 on Sunday, and Senior shot a 68.

Senior also missed a potential winning putt on the first playoff hole by a couple of inches to the right, then had an even closer one from the other side.

"It looked like it was going to go to the left," he said of the first. "The last 3 feet it just went straight. I really thought with 3 feet to go I definitely holed it. It stayed pretty straight the second playoff hole, coming the other way."

Added Lehman: "He hit a beautiful putt. It looked like it couldn't miss. It didn't break."

Lehman won his second Champions Tour major and fifth overall title on the 50-and-over circuit. He has more than doubled up No. 2 Nick Price in the points standings.

Lehman won the Senior PGA Championship last year, beating Fred Couples and David Frost in a playoff after the Minnesotan parred and they both double bogeyed.

Loren Roberts (65) was third at 11 under after a closing birdie, and Michael Allen (69) was 10 under. Third-round leader Mark Calcavecchia shot a 75 to fall into a tie for fifth at 9 under.

The 52-year-old Lehman, the 1996 British Open champion, had to salvage par after his tee shot sailed into the woods on the 17th hole to keep at least a share of the lead.

"I got lucky, I hit a tree which stopped it from going deeper into the woods," he said.

Lehman did make good putts along the way, including an 18-footer for birdie on No. 15 and a difficult 15-footer to save par on No. 10 that he called "easily the key moment of the day."

Senior tied Lehman with a birdie on No. 17, maybe with a little help from a timely gust of wind.

"I had 238 yards to carry the water, which is right on my limit," he said. "But a breeze started coming up just as I was about to hit. I really needed to make four. If wanted to win the tournament, I had to make four there. Pretty good 3-wood just made it over by about 3 yards."

A 35-footer caught the hole's left edge and went a few more feet.

Calcavecchia held the lead for much of the past three days and didn't relinquish it until double bogeying No. 12 for the second straight round.

"That pretty much started the slide both days," he said. "It's beyond disappointing. It just wasn't my day."

Calcavecchia, seeking his first Champions Tour win, had moved to 14 under after 11 holes, but it wasn't a smooth round.

"Every time I hit it not in the fairway, it was in a bad spot," Calcavecchia said.

Lehman had taken the lead after the first round, again without any bogeys, and then spent much of the next few days, in his word, "lurking."

"I made four bogeys for the week and only 17 birdies," he said. "That's not enough birdies, you wouldn't think. I think I played really smart.

"I just kind of kept the ball in play, moving it forward. Hit a lot of greens. A lot of stress-free pars."
