Narciso Elvira
Despite being stuck with a name that always looks like it’s misspelled, the Milwaukee Brewers signed Narciso Elvira out of Mexico in 1987. However, he didn’t crack the Baseball America Top 100 until 1990. He was initially rated as the 23rd best prospect in all of baseball in 1990, and was seen as the 76th best prospect in 1991.
He earned a promotion to Milwaukee in 1990, and actually made four appearances for the Brewers.
Elvira returned to Triple-A in 1991, didn’t get a shot with the Brewers, left for Texas as a free agent in 1992. He left baseball for a few years, came back with the Dodgers, and eventually made it to the Mexican League in 2002, and played there for five years before calling it a career in 2007.
