Jackson Riggs "Warhorse" Stephenson (January 5, 1898 – November 15, 1985) was an American left fielder in Major League Baseball.

Nicknamed Old Hoss,[1] Stephenson played for the Cleveland Indians from 1921 to 1925 and the rest of his career from 1926 to 1934 with the Chicago Cubs.

[5] Stephenson sustained a shoulder injury in a football game in 1920 when he dropped back and was tackled by a pair of linebackers.

His injury to his right shoulder was so bad that he had to end his football career as a quarterback,[citation needed] and as a result it greatly affected his throwing abilities.

[6] His throwing problems made it difficult for him to turn double plays, but his hitting compensated for those fielding woes.

[citation needed] Stephenson quit school at Alabama and immediately made the jump to professional baseball,[2] where he signed with the defending World Series champions Cleveland Indians at the age of 23.

Stephenson made his major league debut on April 13, 1921,[7] and continued to play limitedly during the remainder of the season.

His weak arm and throwing difficulties weakened his fielding abilities at second base,[8] as seen by the 17 errors he committed in the 54 games he played at the position that season.

On September 14, Frank Brower hit a line drive directly to Boston Red Sox first baseman George Burns, and Rube Lutzke and Stephenson were tagged out to complete Burns' unassisted triple play,[6] only the fourth in major league history.

[8] In 1926, Cubs manager Joe McCarthy was able to acquire Stephenson to produce "one of the hardest hitting outfields of all time".

[7] The 1932 Cubs won the pennant over the Pittsburgh Pirates in four games, but were then swept by the New York Yankees in the World Series that featured the Babe's "called shot home run".

[2] Stephenson spent the next five years playing and managing in the minor leagues, but called it quits for good in 1939.

[2][6] After baseball, he went back to Alabama, and he opened up a successful car dealership in Tuscaloosa[3] and a lumber yard in Akron.

Stephenson received a total of only eight votes in his four years on the Hall of Fame ballot in the late 1950s and early 1960s.
