Ireland's Seamus Power was left to rue an inconsistent back nine on round one of the Bank of Utah Championship at the Black Desert Resort.
The Waterford man opened with a round of one-under-par, 70, and sits seven shots back of the clubhouse lead shared by four players, despite making six birdies on the day.
Despite the low scoring, Power was quick out of the starting blocks, making a birdie on the first hole. A bogey on the second followed before first birdies on the fifth and ninth left him at two-under-par at the turn.
However, danger lurked on 11 where he made a double bogey, six, to drop back to level. He would finish with birdies at 14, 15 and 17, and bogeys on 16 and 18 to post a round of 70.
Sudarshan Yellamaraju, Stephen Jaegar, David Lipsky and Stephen Fisk all hold the early lead on eight-under, after opening with rounds of 63.
