Brian Stuard, James Hahn and Cameron Percy co-lead a crowded Safeway Open leaderboard at 16-under, but a host of contenders are right behind them.
Kristoffer Ventura, Sam Burns and Harry Higgs are one shot back, and five other golfers reside in a seventh-place tie at 14-under.
Overall, 28 golfers are within four shots of the lead at Napa, California's Silverado Country Club, whose North course has been a birdie haven.
In other words, it's not inconceivable to believe that anyone within four shots could win this tournament, although those at the back of that pack have many golfers to leap frog before doing so.
