LUTZ, Florida (AP) - Bernhard Langer won for the 10th time on the Champions Tour when the final round of the Outback Steakhouse Pro-Am was called off due to constant rain.

Langer won by default after a birdie on the final hole during the second round on Saturday gave him a one-stroke lead over Mark O'Meara and Mike Reid. Because no player completed their third round, the final result was based on the second-round leaderboard.

The leaders did manage to get on the course Sunday, and Langer made par on the first hole at TPC Tampa Bay while O'Meara chipped in for birdie to force a tie at nine-under.

It ultimately didn't matter when persistent rain washed out the rest of the tournament.

"We don't know what the outcome might have been if we had been able to play 54 holes,'' said Langer, who spent most of the three-hour rain delay playing card games with his family. "Bottom line, it's another second for (O'Meara), and I feel bad for him that he has not won yet, because he's definitely played well enough to do so.''

O'Meara's finished second nine times in four seasons on the Champions Tour, but still has yet to win, and this one may have been the most difficult to take.

Langer and O'Meara managed to get on the course at TPC Tampa Bay before the rain became unbearable, with Langer making par on the first hole and O'Meara chipping in for a birdie, tying them at nine-under.

"I walked over and gave him a high-five and said it was a great shot,'' Langer said. "It was a great shot, and you get some good and bad breaks.''

Langer certainly got a good break Saturday when his approach shot on the final hole hit the flag stick and dropped near the cup. He calmly made the putt for a birdie that gave him a one-shot lead, and ultimately, that's all that mattered.

"There was no guarantee that I was going to go out and shoot a 65 or 66,'' O'Meara said. "A win is still a win (for Langer). He came out on top. Birding the last hole yesterday was pretty important. I don't think he realized that at the time, but now he does.''

Langer remains in second in the Charles Schwab Cup standings behind Fred Couples, who finished tied for 12th at four-under.

The 50-year-old Couples, coming off a sixth-place finish at the Masters last weekend, was trying to tie the record of four-straight Champions Tour wins set by Chi Chi Rodriguez in 1987.

Tom Kite was two strokes back of Langer in fourth place, and defending champion Nick Price joined Keith Fergus and Dan Forsman in a group at six-under.

Tom Watson, who won the tournament in '07 and '08, followed his 18th-place finish at Augusta with a two-day total of five-under. Hal Sutton and Tom Pernice, Jr. also finished at five-under.
