Pat Carroll appeared in 16 games in the Union Association in 1884, mostly at catcher. He played with two different teams and also umpired three games.
It is not clear that the Carroll born in Philly in 1853, who was identified as the ballplayer, is really the right man. There was another Patrick Carroll listed as a ballplayer in the City of Brotherly Love at the time, this one born in Ireland. However, there is a problem with both candidates: they would have been somewhere between 30 and 36 at the time of their professional career, a very advanced age for the period. Another candidate, Patrick Carroll, Jr., was a decade younger and died at the insane asylum in Norristown, PA in 1893; he is listed in the 1886 city directory as a "catcher", although that could mean dog catcher and not the baseball kind. For now, the identity of this player remains a mystery.
