SHEBOYGAN, Wis. — By the time Tiger Woods ' 5-foot putt for par at No. 3 slid past the hole Thursday, he was already in hot pursuit of the ball. The ball was still wobbling the first time he thought about tapping in. Another 10 minutes in the first round of the PGA Championship, after hitting a metal wood off the tee at No. 4, Woods started down the fairway howling to no one in particular, "How (expletive) bad am I putting?' The answer, statistically speaking, is very bad. That Woods let that miss linger well into the next hole — he was still cursing when he arrived at his tee shot — is worse. "I hit it great (Thursday), but I made actually nothing," he said after shooting 3-over 75. "Probably one of the worst putting rounds I've had in a very long time."That left him fighting to make the cut today and put him in danger of missing three consecutive cuts in major championships. Woods also is looking at the possibility that his 2014-15 season will end with no top-10 finishes in just 11 starts. Next week's Wyndham Championship is the last regular-season event on the PGA Tour, and Woods has not qualified for the FedEx Cup playoffs, nor has he committed to play the Wyndham. MORE PHIL STOCK QUESTIONS: After his par 72, Phil Mickelson didn't want to comment on the latest story about an insider stock trading investigation to which he has been linked.The Wall Street Journal reported Wednesday that U.S. authorities are investigating former Dean Foods chairman Tom Davis and whether he leaked confidential information about a corporate spinoff to a professional gambler who may then have tipped off Mickelson."It seemed like it was the same (story) as a year ago," Mickelson said. "It didn't really say anything new."Media reports last year said federal investigators were examining the trading of Mickelson, investor Carl Icahn and sports bettor Billy Walters . The New York Times later reported that the FBI and the Securities and Exchange Commission found no evidence Mickelson improperly traded shares of Clorox. Mickelson was still part of an investigation into Dean Foods trades, the newspaper said.
