Jeremiah Dennis Denny (1859-1927) was a rare ambidextrous third baseman who played professionally for over 20 years, 13 in the majors. He was the last position player to play his entire career without a glove, which would have hindered his ability to use his left hand when the play required. Denny broke in with the Providence Grays and led them to the first inter-league post-season tournament championship as the NL beat the AA in 1884. Jerry teamed with Arthur Irwin at short to create a formidable combination on the left side. He won the first-ever “series” game with a three-run homer off Tim Keefe of the Metropolitans. Providence closed down and Jerry moved to the Maroons in St. Louis for a year and then on to Indianapolis when the team relocated. A reliable batter with good power, Denny compiled a .260 career average and 74 HRs.
