Tiger Woods leads the USPGA at Hazeltine after the second round on seven under par after carding a 70, while Padraig Harrington battled over his round to keep in touch and is in a tie for second place, four shots behind Woods after shooting a one over par 73.
Harrington's day could have been a lot different had he not made three consecutive bogeys on 11, 12 and 13 to go from a share of the lead to rejoining the pack.
To his credit, Harrington steadied himself and rebounded brilliantly with consecutive birdies on 14 and 15.
The 37-year-old arguably hit the shot of the day at the 15th from the bunker, when he hit a three wood 301 yards to about 15 feet. Harrington lipped the eagle putt and holed the birdie effort to go back to four under.
However, a costly bogey on the last, when Harrington missed a four footer for par, means he will not be in the final group with Woods on Saturday.
Rory McIlroy had another roller coaster round at a major tournament, shooting a one over par round of 73 that included four bogeys, one double bogey and five birdies.
Mcllroy was three under par at the 16th tee and in joint third place but a bogey/double bogey/par finish saw him end the day in a tie for 13th, level par for the tournament.
Graeme McDowell had a share or the lead for a brief time early in the day, but his round soon turned sour.
McDowell started on the back nine and was four under par for the tournament after five holes, but six bogeys over the rest of his day were offset by just one birdie, and McDowell carded a 75 for a one over total of 145 to lie in 27th place.
Darren Clarke won’t be around for the weekend after shooting a 76 to go with his opening day 78 for a 10 over par total of 154, six shots outside the cut line.
