Player notes: Stock was primarily a third-baseman, but also played significant amounts at SS and 2B. He was a small man (just 5' 8") with virtually no power, but had decent speed and usually hit for a good average. His 204 hits in 1920 was second to Rogers Hornsby in the National League. He had a career .289 BA, and hit over .300 four consecutive years during his prime. He finished his career with a respectable 1,806 hits.

A career National Leaguer, he had his best years playing for the St. Louis Cardinals, but also played for the Giants, Phillies, and Dodgers. His lone World Series appearance was with Philadelphia in 1915, when the Phillies lost to the Red Sox in five games.

Stock was the father-in-law of Eddie Stanky, who also had a significant major league career.
