name given) was listed in The Official Encyclopedia of Baseball as having played one game for the 1914 Chicago Chi-Feds of the Federal League. Later research showed that the game was caught by the Chi-Feds third-string catcher Clem Clemens — historians reading a handwritten scorecard of the game had incorrectly deciphered "Clemens" as "Deniens". Real players who never played Research by the Society for American Baseball Research (SABR) has identified over 400 players who appeared on major league rosters, but did not appear in a major league game, since 1884. A number of examples are presented here. Pre-1950 Pitcher Bill Stewart was with the 1919 Chicago White Sox, having been signed in December 1918, but he suffered an arm injury falling down a flight of stairs while working as a census taker, and was sent to the minor leagues in May 1919. It is unclear whether he was on the team's active roster. Stewart went on to be an umpire in the National League and an ice hockey referee in the NHL. First baseman Jeff Jones of Harvard was briefly with the 1920 Philadelphia Athletics in early July, but did not play before being assigned to the minor leagues. He was recalled by the A's in late July, but again did not make a major-league appearance. As with several other players of this era, it is not established if Jones was on the A's active roster during the season. Outfielder Lou Almada made the major league roster of the 1927 New York Giants out of spring training, but the Giants did not use him before they optioned him to the minor leagues. In 1933, his brother Mel Almada became the first Mexican to play in the majors. Minor league pitching legend Jake Levy was reported in at least one contemporary account to have signed with the 1927 New York Giants in mid-September, without getting into a game. Peter and Joachim Horvitz' The Big Book of Jewish Baseball list Levy's stint on the Giants bench as having occurred in 1932. However, whether Levy spent any time at all on a Giants' active roster is a matter of dispute. Al Olsen is an unusual example of a verifiable real-life person who did not play in the major leagues, but was included in official major league records for many years. Olsen, a career minor league pitcher, was credited as appearing in the first
