In 2003, Mike Weir became the first Canadian to win a men's major championship and the first left-hander to win the Masters when he defeated Len Mattiace in a playoff.[1] The following year another left-hander, Phil Mickelson, won his first major championship by making a birdie on the final hole to beat Ernie Els by a stroke.[13] Mickelson also won the tournament in 2006 and 2010.
