Pádraig Harrington endured a mixed day on the greens as he opened with a one under 70 to trail Stewart Cink and Martin Laird by six shots after the opening round of the Shriners Hospitals for Children Open in Las Vegas.
Kicking off the 2014-14 PGA Tour season after losing his full playing rights in the US last term, Harrington missed a brace of four footers but still holed his share of putts inside 10 feet at TPC Summerlin.
Starting on the 10th, he had to hole from six feet for par there and then make an 11-footer for bogey at the 11th after pulling his tee shot into trouble.
He missed a four-footer for birdie at the 168-yard 14th but birdied the par-five 16th from seven feet and the 196-yard 17th from 11 feet to turn in one-under 35.
He then had to hole a five footer to save par at the first but missed a four-footer for par at the third after bunkering his approach to slip back to level par for the tournament.
A chance slipped by from 14 feet at the fourth but an 18 footer toppled in at the par-three fifth and while he could only play the remainder in level par, he holed from six feet for par at the eighth before mis-reading an eight-foot birdie chance at the par-five ninth.
Harrington's tally of 30 putts was below average on a day when Cink made seven birdies in an immaculate 65 to lead with Scot Laird on seven under par.
The leading duo are a shot clear of six-man group that features another Scot in Russell Knox, Japan's Hideki Matsuyama, Aussie Jarrod Lyle and American trio Brian Stuard, Bo Van Pelt and Andrew Svoboda
