Danny Wayne Darwin (born October 25, 1955), known as "the Bonham Bullet" and "Dr. Death", is an American professional baseball pitcher and coach, who played in Major League Baseball (MLB) for the Texas Rangers, Milwaukee Brewers, Houston Astros, Boston Red Sox, Toronto Blue Jays, Pittsburgh Pirates, Chicago White Sox, and San Francisco Giants, from 1978 through 1998.

He had a stellar regular season, but Darwin never saw action as a postseason starter because he was being saved for a World Series bid (specifically Game 1) due to the Astros (managed by Hal Lanier) relying on a three-man trio of starters in Nolan Ryan, Mike Scott, and Bob Knepper; the Astros lost in the 1986 National League Championship Series to the New York Mets.

[1] He remained with Houston through 1990, gradually being switched from a starting pitcher to a reliever by his last years with the Astros.

Darwin's return to Texas was short-lived, as he spent the last three years of his career bouncing around between teams.

However, the Giants lost in a sweep, which meant that Darwin had been in a playoff roster twice in his career but did not make an appearance.

Danny's younger brother, Jeff (born 1969), also had a professional baseball career that lasted eleven years.

Jeff, who also graduated from Bonham High School, spent parts of three seasons in the majors, including 1996–1997 with the Chicago White Sox.
