Rory McIlroy left before his round was even over. Tiger Woods had to rally just to stick around.
And with all that drama Friday in the Honda Classic, hardly anyone noticed that Luke Guthrie showed off his potential in a big way with a 7-under-par 63 to take a one-shot lead going into the weekend at PGA National at Palm Beach Gardens, Fla.
Guthrie was at 9-under 131 and had a one-shot lead over Michael Thompson.
McIlroy, who missed the cut in Abu Dhabi and lost in the first round of the Match Play Championship in his previous two starts, made a double bogey on his second hole and rinsed two balls in the water on the 16th hole on his way to a triple bogey.
He hit his approach to the 18th in the water and did not finish the hole. He was 7 over through his eight holes.
He shook hands with Ernie Els and Mark Wilson and was on his way, but not before relaying conflicting messages.
McIlroy told reporters who followed him to his car that it was nothing physical but that he was ‘‘not in a good place mentally.’’
An hour later, he released a statement through his management company that he couldn’t concentrate because of a sore wisdom tooth.
Woods looked as if he might join him. After mixing birdies with bogeys, Woods went bunker-to-bunker, over the green, short of the green, and wound up with a double bogey on the 13th hole that put him one shot under the cut line with five holes to play.
Instead of the second straight week when No. 1 and No. 2 were gone early, Woods answered with a shot into 5 feet for birdie, a 6-foot par putt on the 16th hole, a par save from the back bunker on the 17th that was easier than it looked, and a par save from near the grandstand by the 18th green that was harder than it looked.
He wound up with another 70 to make the cut on the number, nine shots out of the lead.
Also having a tough time was tennis star Serena Williams, following in Woods’s large gallery. She took a picture of the 14-time major champion after his tee shot on the 17th and was scolded by security. The PGA Tour does not allow photos on competition days.
‘‘Apparently u can’t take pics. This security ... yelled at me,’’ she tweeted.
A few minutes later, she posted the photo. And she finished with one last tweet: ‘‘In my Defense peeps always take pics of tennis players.’’
There was no reason to get a snapshot of Camilo Villegas, who joined a dubious list of PGA Tour players who went from first to worst. Villegas, playing primarily on sponsor exemptions this year because he lost his full status, opened with a 64 for his best start in more than a year.
The Colombian was 13 shots worse on Friday in a round of 77 that caused him to miss the cut. The last player to do that was Jim Renner at the Travelers Championship in 2011.
LPGA — Stacy Lewis made six birdies to shoot a 6-under 66 and take a two-stroke lead after the second round of the HSBC Champions at Singapore.
European — Charl Coetzee shot a 7-under 65 and got to 12 under for the clubhouse lead by a stroke when a thunderstorm halted the second round of the Tshwane Open at Centurion, South Africa. Former US amateur champion Peter Uihlein birdied three of his closing four holes for a 66 to get to 10 under.
