Guess the Prospect!
This player was signed by an American League team in 1983, out of Puerto Rico. At the time, Puerto Ricans were not eligible for the amateur draft and could be signed directly as free agents.
A projectable young pitcher, this southpaw made his pro debut in the Midwest League in '83 and pitched brilliantly, posting a 1.30 ERA in 69 innings with a 89/15 K/BB ratio. He followed that up by winning 10 games in the California League at age 19 in '84. He split 1985 between Double-A and Triple-A, pitching well at both levels, then made his major league debut in 1986. He won 11 games in his rookie season and was outstanding at times, if erratic.
This pitcher followed up by winning 14 games in 1987, and was considered a future star or possibly even a superstar. He threw a no-hitter that April, the first thrown by a Puerto Rican in major league history. But he hurt his arm in 1988, damaging his shoulder. He was unable to rehab effectively, and his career was over in 1989 at the age of 24.
