Jon Rahm bounced back from some early struggles Saturday to post a five-under 66 in the second round of the 2017 Dell Technologies Championship, giving him a two-stroke lead at nine under overall at TPC Boston in Norton, Massachusetts.
Paul Casey, Kyle Stanley, Kevin Streelman and Adam Hadwin all hold a share of second place at seven under. The star-studded leaderboard also features Phil Mickelson (-6), Justin Rose (-5) and Jordan Spieth (-5) in the second event of the FedEx Cup playoffs.
Dustin Johnson, the solo leader after Friday's opening round, could only muster a one-over 72 in Round 2, which dropped him into a tie for 15th place.
