Im shot a 7-under 65 on Friday at The American Express to take a one-stroke lead over first-round leader Brandon Hagy and four others.
“Visually from the tee box, it’s a course that I really like and enjoy to play, so I felt really comfortable throughout the round,” Im said.
Emiliano Grillo (66), Francesco Molinari (66) and Doug Ghim (68) were two shots off the lead, and eight more were at 8 under.
After splitting the first two rounds over two courses, the players will all play the once-feared Stadium Course for the final two rounds.
Taylor, who also led the Sony Open after two rounds last week, shot a 66 with six birdies on the Stadium Course.
