ATLANTIC BEACH, Fla. -- Sam Saunders followed his opening 12-under 59 with a 66 on Friday to take a two-stroke lead into the weekend in the Web.com Tour Championship.
Arnold Palmer's grandson, Saunders closed with a double-bogey on his home Atlantic Beach Country Club course a day after shooting the seventh sub-60 round in Web.com Tour history.
Argentina's Julian Etulain was second at 15 under after a 63.
Saunders is trying to regain his PGA Tour card in the four-event Web.com Tour Finals after finishing 129th in the FedEx Cup standings. He entered the week 24th in the race for 25 PGA Tour cards with $27,900 -- the winner Sunday will get $180,000 -- in the first three events.
