The last one to play was Joe Cleary, who played one game in 1945. Andy Leonard was the first. He debuted May 5, 1871.
To celebrate, here's five players born in Ireland. And one in New Jersey. And a nice Irish Ballad by Tom Lehrer.
Patsy Donovan, Boston Red Sox manager, 1911
Paddy O'Connor & Dots Miller, St. Louis Cardinals, 1914
(Dots was born in New Jersey)
