2. Austin Cook chipped in for birdie on his final hole to sign for an 8-under 64, good for solo second-place.
3. Billy Horschel, who ended the 2018 PGA TOUR Season with three top-three finishes in the FedExCup Playoffs, continued his hot play by opening with a 7-under 65 (T3).
4. Scott Piercy, who teamed up with Horschel to win last year’s Zurich Classic, also posted a 65, as did CT Pan.
