Michael Thompson and Richy Werenski shared the lead at the halfway mark of the 3M Open, while Brooks Koepka missed the cut.
Thompson carded a five-under 66 on Friday to be tied for the lead with Werenski (67) at 12 under at TPC Twin Cities in Blaine, Minnesota.
Tony Finau (66) and Talor Gooch (65) are tied for third a shot back of the leaders.
Coming off an eighth-place finish at the Memorial Tournament, Finau made an eagle, four birdies and a bogey.
The American produced some magic for his eagle, holing out from 81 yards at the par-five sixth hole.
