St. Louis Browns outfielder/pinch hitter, Mizell George Platt, was born on August 21, 1920 in West Palm Beach, Florida. "Whitey" Platt would enjoy his best Major League season as a member of the Browns in 1948. He would enjoy a 14-year professional baseball career, with 11 of those seasons in the minor leagues. He would play for three major league teams, but his first opportunity as a everyday player came with the Browns.
White Platt as a member of the 1938 United States team to participate in the Amateur World Series. He would become the first member of the US Amateur program to make it to the big leagues. He would sign his first contract at the age of 18 with the Batavia Clippers in 1939. He would work his way through the minor leagues, playing for the Cornwall Maple Leafs (1939), Moline Plow Boys (1940), Madison Blues (1941), and the Tulsa Oilers (1940-42). He would make his MLB debut as a member of the Chicago Cubs on September 16, 1942. He would play in 24 games with the Cubs (1942-43), but after hitting .167 in 1943 he was sent to the Nashville Volunteers to finish the season.
Whitey Platt would step away from baseball after the 1943 season and join the United States Navy during World War II. He would serve for two years (1944-45) in the Pacific Theater. While in the service, the Cubs placed Platt on waivers, and he was signed by the Chicago White Sox on April 20, 1946.
There is no transaction history to show how he joined the Browns organization, but he would hit 16 home runs while driving in 98 runs playing for the Browns' affiliate, Toledo Mud Hens in 1947. This would lead to Platt making the Browns starting lineup in 1948.
He would be the Browns primary left fielder, collecting 123 hits in 123 games. He would enjoy his best season as a major leaguer, finishing in the top ten of outfielders with 10 triples (6th), 214 putouts (fifth), and .944 fielding percentage (fifth). Platt's best game came against the Boston Red Sox on May 25, 1948, when he would go 4-for-4 including two doubles, a triple, a runs scored, and an RBI. The Browns would shuffle their outfield (bringing in future Rookie of the Year Roy Sievers) and Platt's playing time would drop to a supporting role. His batting average would drop 13 points as his hits totals would drop from 123 to 63 in 1949.
Platt would be released by the Browns and spend the last four seasons of his career in the minor leagues. His final stops would include the Indianapolis Indians (1950-51), Syracuse Chiefs (1951), Miami Beach Flamingos (1952),and the West Palm Beach Indians (1952-53).
There is no record of Platt's life after baseball. But there is no doubt he would spend hours talking about his time in baseball and his treasured two seasons with the St. Louis Browns.
