Seamus Power is five strokes adrift of the lead heading into the weekend after a costly double-bogey at his last hole marred an otherwise fine second round at the 3M Open in Minnesota.
The two-time PGA Tour winner recorded two eagles and four birdies to climb into the top five before a wretched four-putt saw him fall five shots back from the leader, Denmark's Thorbjorn Olesen.
At four-under par overnight and starting on the back nine, Power got a quick start, birdieing the 10th and then draining a 12-footer for eagle on the 12th.
Further birdies followed on the 18th and second before his sole dropped stroke on the par-4 third.
He found another burst down the stretch, firing his second shot to the par-5 sixth into 16ft and sinking the putt. Another birdie putt fell at the seventh to take Power to 11-under.
Much of that was undone following a disastrous ninth, the Waterford golfer missing a three-footer for bogey.
Power, who last won on the PGA Tour at the 2022 Bermuda Championship, has endured an injury-hit season so far, withdrawing from both the Canadian Open and US Open qualifying. He has recorded one top-10 finish in 2025 with a tied-eighth showing at the Valspar Championship in late March.
Olesen followed up his scintillating opening day 62 with a round of 66 to lead at the midway point at 14-under par, one stroke clear of Jake Knapp.
American duo of Pierceson Coody and Sam Stevens are in tied-third on 12-under.
