Samuel B. "Pony" Sager was a Major [League Baseball] left fielder and shortstop for one month in 1871. He played for the Rockford [Forest Citys] of the National Association of Professional [Base Ball Players|National Association].
From May 6 to May 30, Sager played in eight games for the club, four in left field and four at shortstop. He was a below-average fielder at both positions, but did show speed and a strong bat. He went 11-for-39 with five Run [batted in|runs batted in], five stolen bases, and nine runs scored.
One of Sager's teammates on the Forest Citys was 19-year-old future Baseball [Hall of Fame]r Cap Anson, his teammate from Marshalltown, Iowa whom he convinced the team to sign.
