Leon appeared in 31 games for Atlanta in 1977, posting a 4-4 record with a single save over 81.2 innings of work.
But he did also get used as a spot starter, with nine of his appearances as such.
Turns out after some sporadic work in 1978, amounting to just five appearances and 5.2 innings, that would be the end of his Major League career.
His numbers in the big leagues totaled a 14-18 record, with a 3.71 earned run average and 13 saves over 162 games and 310.1 innings pitched.
