CRYSTAL RIVER - Donning a red visor and sharp sunglasses, a slender girl addresses her golf ball and whacks it 200 yards down the center of the Plantation Golf Course fairway.
Then, without so much as a smile, Andrea Adams walks to the ball and takes her next shot.
On the golf course, the Crystal River senior prefers not to show emotion, instead letting her fluid golf swing demonstrate her prowess.
She acts similarly at Crystal River High, where she downplays her academic achievements even as she carries a GPA above 4.5 and dreams of attending Stanford and becoming a heart surgeon.
Good or bad, she keeps her feelings to herself.
"I talk sometimes, but I'm not as social as the other girls," said Adams, a four-year varsity golfer.
As her younger teammates giggle during practice and tournaments, Adams, a 12-handicap, stays focused.
"Even after a bad shot, she's just like, 'ah, darn,' " sophomore teammate Madhuri Shukla said.
Another sophomore, Hope Selander, played a recent practice round with Adams and noticed how her partner knew the nuances of each hole.
And when Selander struggled with her short game, Adams taught the younger player a different stance for chipping.
"It was intimidating," Selander said. "It's kind of weird because we're all not as good as she is and yet we're on the same team."
Still, Adams is patient with her playing partners.
Adams, a golfer since middle school, helped Shukla straighten her slice by telling her to put the ball back in her stance.
The slice still occasionally appears, but Shukla said she appreciates the coaching.
Adams also sometimes assists her teammates with golf etiquette. When golfers drop the pin too close to the hole, Adams asks them to move it toward the fringe.
"She's very patient and soft spoken," Shukla said. "I think she's amazing for being that obsessed with golf."
In practice, Adams mostly works on her own. She receives coaching at Seven Rivers Golf and Country Club, and sometimes retreats there after practicing with her teammates.
The driving range at Plantation is closed for the season, so Adams likes to hit shots at Seven Rivers late in the day. It helps her relax.
"If you're ever stressed out and play golf, it takes it all away," she said.
Crystal River coach Jere DeFoor said he does not mind.
"I don't want to mess her swing up," he said. "She's been playing a long time."
