Marone appeared in only one game for the Pirates in 1970, pitching 2.1 innings and giving up a run, good for an earned run average of 3.86.
In 1969 he had a very nice debut, posting an ERA of 2.55 over 35.1 innings and 29 appearances, going 1-1 with 25 strikeouts against 13 walks.
He’d go on to pitch two more seasons in the Pirates Minor League system through 1972, but never make it back to a Major League mound again, finishing up with 30 appearances and that 1-1 record from 1969, with a very nice 2.63 ERA.
