Summary:
Penn finished this season with a 17-7-1 overall record. Most notably, they were undefeated against Lehigh (4-0-1) and averaged around 7.3 runs per game for the season. They seemed to struggle against Yale and the Athletics though, losing twice to each.

Two members of this team went on to play professional baseball: Bowman and Darragh. Wagenhurst played professional ball before coming to Penn.

Note that the list of team members varies slightly from source to source. Included here is everyone named in the 1891 yearbook, the Athletic Association history of Penn athletics published in 1913, or both. The yearbook for this year also includes a "reserve" list.
