Rondon made his debut during the bicentennial year, and went on to post a 2-2 record over those 19 games, with a 5.70 earned run average and 21 strikeouts in 53.2 innings pitched.
Sadly for him that didn’t translate to a permanent spot on a Major League roster, and he’d spend the next two seasons in the minors for both the Houston and New York Yankee organizations before making it back up to the big leagues for four games with the Chicago White Sox in 1979.
Those four games, in which he posted no record along with a 3.72 ERA would be the last at the Major League level, as he would find himself playing in the Los Angeles Dodgers minor league system through 1981 before calling it a career.
All told he’d finish with a 2-2 record over 23 games, with a 5.40 ERA and 24 K’s in 63.1 innings of work.
