Dennis Martinez was named as the Astros bullpen coach in October 2012. Prior to joining the Astros, Martinez spent six seasons (2007-12) as a coach in the St. Louis Cardinals organization, most recently serving as pitching coach for Class A Springfield. Martinez also served as a special assistant and a Spring Training instructor in the Baltimore Orioles organization before his stint with the Cardinals.
Martinez enjoyed an outstanding, 23-year career (1976-98) as a Major League pitcher, compiling a 245-193 career record in 692 games (562 starts) with a 3.70 ERA. His 245 wins rank first all-time in Major League history among Latin American-born pitchers. He was also the first Nicaraguan-born player in Major League history. Nicknamed "El Presidente" by former Orioles teammate Ken Singleton, Martinez had several highlights in his career, including pitching the 13th perfect game in Major League history, a 2-0 win at Dodger Stadium on July 28, 1991, while with the Montreal Expos. Martinez appeared in four All-Star Games (1990-92, 1995), led the AL in wins in 1981 and led the NL in both ERA (2.39) and shutouts (5) in 1991. Martinez reached 220-plus innings nine times in his career, including a career-high and AL-best 292.1 innings for the AL Champion Orioles in 1979. From 1988-93 while with Montreal, Martinez posted an 86-62 mark in 198 games with a 2.92 ERA, ranking fourth in the NL in wins and third in ERA, complete games (38) and innings pitched (1,366.1) over that span. He also reached 220-plus innings in those six consecutive seasons. Martinez pitched in two World Series, in 1979 for Baltimore and in 1995 for Cleveland, and was 2-2 in 12 postseason appearances overall (six starts) with a 3.32 ERA On Sept. 28, 1993, Martinez won his 100th game for the Expos, becoming one of just nine Major League pitchers ever with at least 100 wins in both leagues. Others to do that are Jim Bunning, Ferguson Jenkins, Al Orth, Gaylord Perry, Kevin Brown, Randy Johnson, Nolan Ryan and Cy Young.
An icon in his native country of Nicaragua, Martinez has met with President Daniel Ortega and is involved with developing baseball in the Latin American country. In 1998, Nicaragua renamed a 30,100 seat baseball stadium in the nation's capital Managua in his honor (Dennis Martinez National Stadium). He has a son, Ricky, who is currently a right-handed pitcher in the Astros minor league system (originally signed by the Cardinals as a non-drafted free agent out of Nova Southeastern University in 2010). Martinez currently resides in Miami.
