Paul Casey and Austin Cook finished Friday's second round tied at six under for the tournament, though 12 other players are within three strokes of that pair, including Dustin Johnson (four under) and Jon Rahm (three under).
Casey was superb on the Copperhead Course in Palm Harbor, Florida, shooting up the leaderboard with a five-under 66, tied with Tyler Duncan (two over) for the best score in the round, while Cook finished four under for the day.
