BLAINE, Minn. – Michael Thompson and Richy Werenski topped the 3M Open leaderboard going onto the weekend, Tony Finau and Talor Gooch climbed within a stroke and stars Brooks Koepka and Tommy Fleetwood struggled again Friday.In warmer and windier conditions on the quiet, spectator-free TPC Twin Cities course, the scores crept up after Werenski led the first-round pack with an 8-under 63.
The 24-year-old, who's winless on the PGA Tour, followed up with a 67. Thompson caught him with a 66.Koepka, at the other end of the board, was on the who's-who list of players to miss the cut.
The four-time major champion shot a 71 to finish at 1 under, pulling a birdie putt attempt wide right on the 18th that would have extended his stay in Minnesota..
