Fighter Dan Henderson's sis on golf show

You wouldn't expect MMA fighter Dan Henderson to be much of a golf fan. After all, the 2011 Strikeforce light heavyweight champion and Pride middleweight and welterweight title holder spends most of his time in grueling combat -- a far cry from the serene atmosphere of a golf course.

But there's a reason you might find him on the greens: his 25-year-old younger sister Selanee Henderson.

"My brother has accomplished so much and I expect so much of myself," Selanee said.

The younger Henderson turned pro in 2008 after graduating from Cal-Irvine, and while she's faced plenty of competition playing again the likes of Paula Creamer, Cristie Kerr and Annika Sorenstam, she didn't know what real pressure was like until she signed on for the Golf Channel series Big Break Atlantis.

"I played in the U.S. Open in 2007 when I was still in college, but I've never been so nervous than when I had to hit shots on 'Big Break'," said Selanee, who joins this season's all-female cast, set to premiere on the Golf Channel on May 14 at 9 p.m. "Each shot can ultimately get you kicked off the show. It's not like real golf where you can hit a bad shot and recover and still make a birdie on the hole. There is so much pressure riding on every single shot."

The show, in its 17th season, pits 12 professional and amateur players against each other in a series of golf challenges. The last woman standing wins an exception for an LPGA Tour tournament and cash.

It was just the push Selanee needed, who was struggling before the show's filming in January with the yips -- a movement disorder that usually affects a players putting but had affected her irons, causing her to tense up and flinch.

"It's tough trying to overcome that mental block but Big Break really helped force me to get through pressure situations and get through that anxiety," Selanee said. "My brother's probably more mentally tough than me. He doesn't have a fear of failure. I'm working on that."

The elder Henderson is set to fight UFC light heavyweight champion Jon Jones in September.

"She's always been a fan of mine as much as she's my sister and I'm probably the same," he said. "We're both in individual sports, and you need a whole team to help get you ready, but it does fall on your shoulders to get the job done."

While the genes may be all in the family, their skill sets are a different story.

"I'm not very good at golf," Dan admitted. "She started beating me when she was probably ten years old."

Selanee won't disagree.

"It feels good that I can beat him at something. ... But I'm expected to win."
