James Nagle is disqualified from the U.S. Junior Amateur for repeated use of green-reading materials.

Nagle used a yardage book with green maps more than once during his six-over 76 on Saucon Valley's Grace Course. Model Local Rule G-12 requires disqualification after a second violation.

Nagle said he approached a rules official after his playing partner warned him. Officials reviewed the incidents after his round and disqualified him when he confirmed repeated use for reading greens.
