Gregory Alan Maddux (born April 14, 1966), nicknamed “Mad Dog” and “The Professor”, is a former Major League Baseball pitcher. He was the first pitcher in major league history to win the Cy Young Award for four consecutive years (1992–1995), a feat matched only by Randy Johnson (1999–2002). During those four consecutive seasons, Maddux had a 75-29 record with a 1.98 ERA, while allowing less than one runner per inning. Maddux is the only pitcher in MLB history to win at least 15 game.
