Johnny Frederick was a great rookie whose career declined because of an injury that would not go away.
Frederick, who broke into the majors at age 27, led the league with 52 doubles as a rookie with the Brooklyn Robins in 1929. His doubles total remains the all-time major league rookie record by a wide margin (the American League record is 47). Thereafter his doubles and home runs tended to decline each year, although his slugging percentage in 1932 (in 118 games) was among the league leaders.
His fielding range, great as a rookie, also declined as he got older, and he moved from being a center fielder to being a right fielder.
The Dodgers Encyclopedia indicates that Frederick started in professional ball in the Western Canada League in 1922. He suffered a leg injury in 1930 that worsened as time went on, eventually relegating him largely to pinch-hitting duties. After major league ball, he continued to hit .300 in minor league ball for six more seasons.
In 2005 he was elected to the Pacific Coast League Hall of Fame.
