first_imgNEWPORT BEACH, Calif. – Fred Couples withdrew from the Toshiba Classic because of back pain Thursday, a day before the start of play in the PGA Tour Champions event. The 58-year-old Couples won the tournament in 2010 and 2014 and lives in the area. Long hampered by back problems, Couples hasn’t played a tournament since tying for sixth in January in Hawaii at the season-opening Mitsubishi Electric Championship. The Hall of Famer has 13 victories on the 50-and-over tour after winning 15 times on the PGA Tour.last_img
