Luis Aponte was a 28-year-old in just his second Major League stint in 1981. He had come up late in the season in 1980 to make his Major League debut. He pitched in just four games but had a 1.29 ERA. He did the same thing in 1981, pitching in seven games with an even more impressive 0.57 ERA and a 1-0 record. Aponte pitched 15.2 innings and struck out 11, while walking just three. He also picked up his first Major League save after pitching an inning and a third on Oct. 4. It was an impressive enough season to ensure that Aponte would be given an opportunity at a Major League job in 1982.
Aponte made the most of that opportunity as he spent the next two seasons in Boston's bullpen as a middle reliever and was reasonably successful. He was 7-6 with a 3.37 ERA in the next two seasons before being traded to Cleveland prior to the 1984 season. Aponte was not nearly as impressive in Cleveland though and was released after the season. That was it for Aponte in the Majors.
