Ryan Michael Madson (born August 28, 1980 in Long Beach, California), nicknamed "Mad Dog", is a Major League Baseball relief pitcher with the Philadelphia Phillies. Madson throws a four-seam fastball that ranges from 94 to 98 mph, a cutter that ranges from 86 to 92 mph, and a circle changeup that ranges from 76 to 84 mph.
Madson graduated from Valley View High School (Moreno Valley, California) in 1998 with a 3.5 GPA. His uncle, Steve Barr, was in the Boston Red Sox and Texas Rangers systems from 1969–1975. Madson was drafted by the Phillies in the 9th round (254th overall) of the 1998 Major League Baseball Draft.
Highly regarded by the Phillies ever since they drafted him, Madson got to the major league level for good in 2004 as a relief pitcher. In 2005, he started out well, but appeared to wear down late in the season, finishing with a 4.14 ERA in 87 innings.
