Bogey-free Jon Rahm leads after Northern Trust second round

World No. 1 Jon Rahm of Spain remained bogey-free through 36 holes and will carry a one-shot lead into the weekend in the Northern Trust at Liberty National in Jersey City, N.J.

Rahm's 4-under 67 on Friday was enough to get him to 12 under, one stroke ahead of Tony Finau, who posted a second-round, 7-under 64.

Xander Schauffele shot the low round of the day, a 9-under 62, to join first-round co-leader Justin Thomas (69)
