Juan Antonio Marichal Sánchez, nicknamed "the Dominican Dandy", is a Dominican former right-handed pitcher who played 16 seasons in Major League Baseball from 1960 to 1975, mostly with the San Francisco Giants. Known for his high leg kick, variety of pitches, arm angles and deliveries, pinpoint control, and durability, Marichal won 18 games to help the Giants reach the 1962 World Series, and went on to earn 191 victories in the 1960s, the most of any major league pitcher. He won over 20 games six times, on each occasion posting an earned run average (ERA) below 2.50 and striking out more than 200 batters, and became the first right-hander since Bob Feller to win 25 games three times; his 26 wins in 1968 remain a San Francisco era record.
Marichal led the National League (NL) in wins, innings pitched, complete games and shutouts twice each. He was often overshadowed by his contemporaries Sandy Koufax and Bob Gibson; in each of Marichal's four best seasons, either Koufax or Gibson won the Cy Young Award, always by unanimous vote.
