 The ballplayer Morris started every game of that series save for one.The only game he did not start was on May 14, the date the previously known "P. Morris" appeared in a game for the Nationals, an away game against the Chicago Browns, another Union Association team.As the Nationals were known to have a link to the Milwaukee club, it was surmised by the writer Morris and SABR editor Bill Carle that the player who appeared for Washington on the 14th was indeed the ballplayer Peter Morris.
