Sheriff Blake pitched 10 years in the major leagues, mostly with the Chicago Cubs in the 1920s. He was 14-13 on the Cubs' pennant-winning 1929 team. In 1928 he posted an ERA of 2.47 with a record of 17-11.
He is one of only four major league players to come from West Virginia Wesleyan College (through 2006), along with Greasy Neale, his contemporary in the major leagues. Blake was in college in 1920, and then made his major league debut in June 1920 with the Pittsburgh Pirates. After that, though, he didn't come back to the majors until 1924.
After the 1931 season, he was out of the majors until 1937, when he came back for 29 games at the age of 37.
