Seamus Power birdied his final two holes to keep himself in the mix heading for the weekend at the American Express in California.

FULL LEADERBOARD

The Waterford man had opened with a seven-under-par 65 on Thursday that left him three off the lead, but things were a little more laboured in his second round.

He got to the turn on level par after two birdies were offset by a couple of bogeys, having started on the 10th hole.

Power picked up momentum with birdies on the par-four first and the par-five fifth, and though he gave one back on the sixth, a strong finish hoisted up to ten-under overall, four shots off leaders Patrick Cantlay and Lee Hodges.

Cantlay survived two bogeys over his final nine holes to card a four-under 68 and hold a one-stroke lead.

The reigning FedEx Cup champion moved to 14-under for the week, leading Tom Hoge by one shot. A five-way tie for third at 12-under includes Will Zalatoris, who fired an 11-under 61.
