EDMOND, Okla. -- Colin Montgomerie is getting used to winning these big events.
The Scotsman defeated Gene Sauers in a playoff to claim the U.S. Senior Open title Sunday at Oak Tree National.
Montgomerie failed to win in 71 PGA Tour majors and four Champions Tour majors until May, when he won the Senior PGA Championship. Now, he has won two of his past three majors to become just the fifth golfer to win both the Senior PGA Championship and U.S. Senior Open in the same year.
The 51-year-old said he has become more patient with age.
''You have to play intelligent golf, and I think I've matured enough to realize that and play more within myself sometimes, including today - to play away from some pins so you don't make bogies, and you realize that in major golf, pars are usually good enough, especially in the USGA events,'' he said.
Montgomerie reached another milestone by winning his first professional playoff in nine tries. Most famously, he lost to Ernie Els at the 1994 U.S. Open and to Steve Elkington in sudden death at the 1995 PGA Championship.
''I've been close in these USGA championships a couple of times,'' he said. ''I've lost in a playoff and been one shot behind a couple of times, and you have to wait to (over age) 50 to finally win one.''
On the 18th hole of regulation, Montgomerie parred, then waited. Sauers' second shot landed about 10 feet from the hole, giving him a chance to win the tournament with a birdie. His putt lipped out, and he parred to force the playoff.
''I guess I just may have misread that putt the first time around, didn't play enough break,'' Sauers said. ''Hit a good putt, broke right at the hole at the last second.''
Montgomerie led at the end of the first and second days of the Senior Open, but entered Sunday's action four shots behind Sauers. He shot a 2-under 69 to force the playoff and now feels he is capable of playing just as well on the PGA Tour.
''My golf is as good as it was in the `90s, when I was No. 2 in the world,'' he said. ''It really is. I can't see any difference between that.''
Montgomerie and Sauers entered the playoff at 5 under. Montgomerie entered the third extra hole with a one-shot lead, then sank a putt on 18 to par the hole and claim the win.
It was the first playoff at a U.S. Senior Open since 2002, when
''For my wife and three kids to be here is fantastic, and I'm just sorry for them,'' Montgomerie said. ''It was very hot for them to walk around. They had to walk 21 holes today. Eighteen is enough.''
Sauers' performance was impressive, given his circumstances. He said a reaction to a wrongly prescribed medication several years ago caused Stevens-Johnson syndrome, a disorder that burned the skin on his arms and legs from the inside out. He got out of the hospital in June 2011 and eventually returned to the course.
Sauers hadn't finished higher than 15th in a Champions Tour event this year, and hadn't won an event of any kind since the 2002 Air Canada Championship on the PGA Tour. He has never won a major on the Champions or PGA tours, but he was thankful to be close.
''I'm glad to be able to be here to play with my friends again,'' he said. ''I'm glad to be here and I'm coming back. I feel good about my game, and there's always next week.''
