"Muñoz made his major league debut in 2004 for the Chicago White Sox in a start against the Montreal Expos. It was a disaster, as Muñoz allowed eleven runs in three innings (including nine in the second inning alone) tying for third all-time for most runs allowed in a major league debut. (Bill James' "Game Score" statistic, which measures pitcher starts — 50 is average, 90 is exceptional, below 20 is poor — scores Munoz' start at minus-7, the worst for a debut start since at least 1918.) Amazingly, Muñoz almost did not emerge as the losing pitcher, as the Sox mounted an incredible comeback, finally falling 17-14. Muñoz went back to the minors, then returned in September, pitching fairly well in relief."
