Hazen Shirley "Kiki" Cuyler (/ˈkaɪlər/; August 30, 1898 – February 11, 1950) was a Major League Baseball right fielder from 1921 until 1938. Cuyler established a reputation as an outstanding hitter with great speed. He regularly batted .350 or higher and finished with a .321 lifetime batting average. In 1925 Cuyler hit 18 home runs and 102 RBI. Cuyler's Pirates won the World Series that year, the only time in his career that he contributed to a World Series winner.
Cuyler was born in Harrisville, Michigan on August 30, 1898. He was one of six children born to George and Anna Cuyler. His father had come to the United States from Canada, but his ancestors lived in New York from the 17th century until they moved to Canada at the start of the Revolutionary War.
Cuyler broke into the big leagues in 1921 with the Pittsburgh Pirates and became a fixture in the lineup in 1924. In August 1925, Cuyler hit two inside-the-park home runs in a single game at Baker Bowl, the very compact baseball stadium in Philadelphia. Cuyler led the 1925 Pirates to a World Series title, the only one of his career. In 1927, Cuyler was benched for nearly half the season because of a dispute with first-year manager Donie Bush. The Pirates again went to the World Series, but Cuyler did not play. That November, Cuyler was traded to the Chicago Cubs for Sparky Adams and Pete Scott. Between 1926 and 1930, the 1927 season was the only time that Cuyler did not lead the league in stolen bases.
Between 1931 and his retirement in 1938, Cuyler never stole more than 16 bases in a season. Though he hit for a .338 batting average and a league-leading 42 doubles in 1934, Cuyler was made a free agent by July 1935. He signed with the Cincinnati Reds, hitting .326 in 1936 and .271 in 1937. He was released after the 1937 season and signed with the Brooklyn Dodgers for his final season in 1938. Cuyler finished his career with a .321 batting average, 128 home runs, 1065 RBI and 328 stolen bases.
