By Frank Pingue OAKMONT, Pennsylvania (Reuters) -Overnight U.S. Open leader J.J. Spaun shook off his first bogey of the week to reach the midway mark of his second round level with Thriston Lawrence at Oakmont Country Club where Rory McIlroy was flirting with the projected cut line.

J.J. Spaun finishes the first round of the U.S. Open with a one-shot lead after Scottie Scheffler struggles with a round of 73.
