Charlie Beljan was worried about keeping his PGA Tour card when he showed up at Disney for the final tournament of the year in Lake Buena Vista, Fla.

That changed Friday over five frightening hours when he felt a shortness of breath and his heart racing, and he eventually told his caddie that he thought he was going to die.

He called for paramedics at the turn and was told his blood pressure was not good. He sat in the fairway to rest and kneeled on the green to try to steady himself.

In one of the most remarkable rounds of the year, the 28-year-old rookie fought through it for an 8-under 64 to take a three-shot lead.

Moments after signing his card, Beljan was loaded onto a stretcher. His eyes were closed, his head tilted back and his arms were folded across his stomach as paramedics loaded him into an ambulance parked beyond the 18th green at the Palm Course.

"I think he was scared," said his caddie, Rick Adcox. "He kept saying he thought he was going to die. He just had that feeling. I don't know why. But it was spooky."

A few hours later, his agent sent a text to tour officials from Celebration Hospital that Beljan was waiting on tests, feeling better and hopeful of being discharged Friday night, though that was not certain. In a later text, agent Andy Dawson said even if Beljan remained in the hospital overnight, he still planned to play the third round.

Beljan was in the lead for the first time after any round going into the weekend at the Children's Miracle Network Hospitals Classic.

It could not have come at a better time because he is No. 139 on the money list, and only the top 125 keep their full cards for next year.

And yet the surreal day ended with Beljan not even sure he would be able to play on the weekend.

The tour said Beljan complained of an elevated heart rate, shortness of breath and heart palpitations. Adcox said Beljan told him of numbness in his arms and feeling faint.

"I thought they were going to stop him on 10 when they told him what the blood pressure was," he said. "He just said, 'I'm going to keep going until either I pass out or they take me off.' "

Beljan's struggle was painfully clear. That he wound up in the lead at 12-under 132 was simply amazing.

He had a three-shot lead over seven players, including Charles Howell III and first-round leader Charlie Wi, who shot a 1-under 71 on the more difficult Magnolia course.

"It was bizarre," said Edward Loar, who played with Beljan. "It sure didn't affect his golf."

LPGA Tour: Angela Stanford shot a 5-under 67 to take a two-stroke lead over Inbee Park (68) at the Lorena Ochoa Invitational. Stanford had an 11-under 133 total at Guadalajara (Mexico) Country Club. Stanford graduate Michelle Wie, tied for the first-round lead, had a 75 to drop into a tie for 12th at 3 under. Ochoa (72), who retired from the tour in 2010, was 1 under.

European Tour: Simon Dyson and Chapchai Nirat topped the Singapore Open leader board at 6 under when rain again disrupted play. Dyson finished 13 holes and Nirat nine before play was suspended. Rory McIlroy was 1 under overall with six holes left in the second round. Phil Mickelson has yet to start his second round. He opened with a 73.
