Calcavecchia bowing out of US PGA Tour after 50th birthday

Former Open champion Mark Calcavecchia, who has his 50th birthday on June 12, is likely to play for the last time on the US PGA Tour in the Memorial Tournament.
He has teed it up 736 times on the US Tour, winning 13 tournaments and earning just under $24 million in a career that has not had very many dull moments.
Calcavecchia moved from Nebraska to South Florida when he was a teenager and immediately got involved in the junior golf scene. He competed throughout high school against Jack Nicklaus II, whose father often came out to their junior events.
"We lived about two miles from each other," he said.
Calcavecchia first played Muirfield Village in 1987, the year after his first US PGA Tour victory, and this will be his 24th consecutive year at the Memorial. The closest he came to winning was in 1995, when he tied for second behind Greg Norman.
"Someone asked me if I was excited to be going out there to the Champions Tour," Calcavecchia said. "I said I would be excited if the hole was bigger. But I think it's the same size out there, so I'm not that excited. I can miss 'em out there same as I can miss 'em out here."
It won't be the last time Calcavecchia tees it up against Tiger Woods or Phil Mickelson. He plans to go to St Andrews for the Open, where he is exempt for another 10 years.
Calcavecchia won a stroke-play play-off against Wayne Grady and Greg Norman at the conclusion of the 1989 Open championship at Royal Troon.

AMERICAN WINNERS IN SHORT SUPPLY
The US PGA Tour has gone four consecutive weeks without an American winner, the longest stretch since international players won seven straight events in 2008. That's an entire month without an American winner.
And that's nothing compared with the LPGA Tour.
Michelle Wie of Hawaii is the only American winner on the LPGA Tour over the past year, which covers 26 official tournaments (and does not include the U.S. victory in the Solheim Cup).
Angela Stanford had a chance to become the LPGA's first American winner this year until losing in the final of the Match Play Championship in New Jersey to Sun Young Yoo.
What to make of it?
"I don't make anything of it," Stanford said. "I think you guys make a lot out of it. We're a global tour, and I wasn't trying any less out there. If anything, I was trying harder because I know that it just kind of keeps coming up."
