What it means: Chappell opened with a 6-under 66 on the Plantation Course, then followed with a 5-under 65 on the more difficult Seaside Course. Twice a runner-up on Tour, most recently at the 2013 Memorial, the former UCLA product remains in search of his first win and now takes a one-shot lead into the weekend over a pair of seasoned veterans.
Round of the day: Chappell opened with three birdies over his first eight holes, but he stood one shot off the pace on the par-5 15th. There, he holed a lengthy bunker shot to take sole possession of the lead and closed with three more pars to finish a round of 5-under 65 that featured only one bogey despite blustery conditions.
Best of the rest: Jacobson missed much of last season because of a health scare with his son, but the Swede is back on the leaderboard after a 5-under 67 on the Plantation Course. Jacobson was only 1 under through 11 holes but closed with a flurry, carding birdies on four of his final seven holes. The score put moved him within a shot of Chappell as he looks for his first win since the 2011 Travelers Championship.
Biggest disappointment: Sam Saunders opened with a 66 on the more difficult Seaside layout, but he was unable to maintain that momentum during Friday's second round. Facing the Plantation Course, Saunders struggled to a 4-over 76 that included only two birdies and a double bogey on the par-5 fourth hole. At even par, he missed the cut by two shots.
Main storyline heading into Saturday: Chappell replaces Kisner as the tournament leader in search of a breakthrough win, but the top of the leaderboard remains somewhat inexperienced - each of the top eight players has no more than one win to his credit. The lone veteran with the most hardware near the top is McDowell, who shows no signs of slowing down after returning to the winner's circle last week in Mexico.
Shot of the day:
Quote of the day: "I'd take him as a partner any day." - Tournament host Davis Love III, who made the cut after rounds of 70-70 while his son, Dru, missed the cut after a second-round 76. The two played the first two rounds together and plan to pair again next month at the Father/Son Challenge.
