"I've seen that a lot, but not at this golf course," he said.
Vijay Singh, playing one day after he sued the PGA Tour for its handling of his doping case, was largely ignored while playing in the group behind Woods. One fan wore felt deer antlers in the bleachers behind the first tee — Singh's case involved taking deer antler spray — but only a dozen or so people followed the 50-year-old Fijian on the back nine and it was a quiet day.
At one point, Singh let out a hearty laugh walking off the tee with Robert Garrigus and J.J. Henry. His golf wasn't the subject of the laughter. Singh hit into the water on the last hole and made bogey for a 74, leaving him in danger of missing the cut.
So ended a first round filled with plenty of action — a record-tying score by a player hardly anyone knows, McIlroy breaking par for the first time at Sawgrass, 17 balls in the water around the island-green 17th and 33 rounds in the 60s. Padraig Harrington followed an eagle with a double bogey. Michael Thompson made a hole-in-one.
But it all started with Castro, a 27-year-old who felt like he couldn't miss.
"I don't think anyone has figured out what the secret is to this place," Castro said.
Woods, Webb Simpson and Ryan Palmer each had a 67, the lowest score from the afternoon.
McIlroy also played in the morning, in the same group as Masters champion Adam Scott (69) and Steve Stricker (67). The 24-year-old from Northern Ireland had never made the cut or even broken par at The Players, but McIlroy figured it out on a gorgeous morning by dialing it back off the tee and letting his iron play take over. McIlroy never came seriously close to a bogey, and he didn't hit driver once on the front nine.
