DORAL — Hunter Mahan shot 1-under 71, good enough to keep his one-shot lead at the end of a long day at the WGC-Cadillac Championship on Friday. His comfort level, though, might not be quite the same.
After leading by three midway through the second round, two late bogeys brought him back to the pack as morning breezes fizzled out at the TPC Blue Monster.
Nor will he get much breathing room from the guy right behind him — world No. 1 Martin Kaymer.
Kaymer shot 70, carding two birdies to go with 16 pars.
"He's playing great," Mahan said. "It's been pretty impressive because he's not just playing great — he's actually winning and that's what sets the good players and great players apart."
Mahan was 9-under 135 at the midway point. Italy's Francesco Molinari (68) joined Kaymer at 136.
Tiger Woods birdied once among the three holes he played to complete the first round, then two of his first three of the second round. But he didn't produce another all day and shot 2-over 74. That left the former No. 1 player at par after 36 holes.
"I hit numerous good shots again," Woods said. "If I putt normal (Friday), I'm 3- or 4-under par. It's not that bad."
His tee shot at No. 2 was bad — a quick-diving smother hook that traveled just 122 yards into the left rough and didn't make it past the front tees. He bogeyed the hole.
"It's not the first time I hit a snipe," he said. "Did it at the Masters."
Japanese teen Ryo Ishikawa, who awoke to news of an earthquake and massive tsunami in his homeland, completed an opening 65 but dipped to 76 in the second round. Along with countrymen Yuta Ikeda and Hiroyuki Fujita, Ishikawa, 19, had to gather his focus after learning of the 8.9-magnitude quake in Japan. Ishikawa was able to reach his parents in suburban Tokyo.
PRICE TIES TOUR RECORD: Nick Price matched the lowest round in Champions Tour history, eagling the 15th and 18th and carding seven birdies for a career-best 11-under 60 at the Toshiba Classic in Newport Beach, Calif. "There was a flash in my mind when I eagled 15, I sort of thought to myself, 'If I birdie the last three holes, I can break 60,' " Price said. "I've never done that before." He's the seventh player on the over-50 tour to shoot 60.
PGA: Chris Tidland shot 9-under 63 for a share of the second-round lead at the Puerto Rico Open in Rio Grande. Tidland tied the course record set by Derek Lamely in his win last year and tied by James Driscoll on Thursday. Troy Matteson shot his second straight 67, and Driscoll had 71 to join Tidland at 10-under 134.
