Despite making his MLB debut as a 31-year-old rookie, Kinder had a reputable career.
Kinder was among the best starting pitchers in the American League in 1949, going 23–6 and leading the league in shutouts (6) and a .793 winning percentage. Then, in 1951, the Red Sox, desperate for a relief pitcher, moved him to the pen where he shined as the best reliever in the AL until 1955.
The Cardinals acquired him in 1955 at/near the end of his career.
