NEW YORK (AFP) - Top-ranked Jon Rahm, the reigning US Open champion, fired a bogey-free four-under par 67 to grab a one-stroke lead during Friday's (Aug 20) second round of the US PGA Northern Trust tournament.

The 26-year-old Spaniard stood on 12-under par 130 without a bogey through 36 holes at Liberty National in suburban New York at the first FedEx Cup playoff event.
