Defending US Senior Open champ Roger Chapman says life changed after his big 2012 breakthrough

Roger Chapman is a lot more recognizable in his hometown of Ascott, England, after winning two majors on the Champions Tour last year.

Chapman would have been best described as a journeyman on the European Tour before he broke through last year with wins at the Senior PGA Championship and U.S. Senior Open. He said Monday at the Senior Open media day in Omaha, Neb., that his life has undergone an "enormous change" since.

Chapman's 2012 campaign allowed him to make his first appearance in the Master's last month, and he'll play for the first time in the U.S. Open at Merion in June.

The Senior Open is July 11-14 at the Omaha Country Club.
