Mike Cuellar, Cuban-American baseball player (d. 2010)
Miguel Ángel Cuellar Santana (KWAY-ar; May 8, 1937 – April 2, 2010) was a Cuban professional baseball player. He played for 15 seasons in Major League Baseball as a left-handed pitcher in 1959 and from 1964 through 1977, most prominently as a member of the Baltimore Orioles who won the American League (AL) pennant in each of Cuellar's first three seasons with the team. During that time, Cuellar and the Orioles won the 1970 World Series. Cuellar also played for the Cincinnati Reds, St. Louis Cardinals, Houston Astros and California Angels.

Cuellar and Denny McLain each won the AL Cy Young Award in 1969, due to a tie in the voting. For the Orioles, Cuellar won 20-or-more games in a season four times from 1969 through 1974. Along with Jim Palmer, Dave McNally, and Pat Dobson, he was one of four Oriole starters to win at least 20 games in 1971. Cuellar, nicknamed Crazy Horse because of his superstitious nature, ranks among Baltimore's top five career leaders in wins (143), strikeouts (1,011), shutouts (30) and innings pitched (2,028). In 1982, Cuellar was inducted into the Baltimore Orioles Hall of Fame.
