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.

Two-time major champion Xander Schauffele had some words of advice for J.J. Spaun, who grabbed the early clubhouse lead with a 4-under 66 in the opening round of the 125th U.S. Open at Oakmont Country Club.
