The world No 4 then temporarily moved three shots clear after following a 20-foot gain at the third with another birdie at the next, only to slip back with a bogey at the sixth and a three-putt blemish at the par-four ninth. Beginning on the back nine, Watson looked in impressive form at Plainfield Country Club, as playing partner Jordan Spieth struggled to his worst round of the year with a bogey-filled 74 . Levin and Villegas both made strong starts to also post 65s, with Finau moving joint-top of the leaderboard after opening with three consecutive birdies.
- Today the only one I messed up on was the par three, where I made the bogey.
- Vijay Singh, part of the final group, looked set to threaten the leaders when a 12-foot birdie at the first moved him one off the pace, only for the veteran to drop three shots in the space of four holes late in his round to join Hideki Matsuyama in the group on one under.
