Juan Manuel Nieves Cruz (born January 5, 1965 in Las Lomas, Puerto Rico) is a former pitcher in Major League Baseball who, on April 15, 1987 against the Baltimore Orioles, became the second-youngest player in major league history to throw a no-hitter, and so far the only Milwaukee Brewer to do so. [1]

He was signed by the Brewers after graduating from Avon Old Farms school in Connecticut. After playing for the Milwaukee Brewers from 1986 to 1988, he suffered a career-ending arm injury. He is currently the bullpen coach for the Chicago White Sox.

Nieves' no-hitter became the first ever thrown by a Puerto Rican in Major League Baseball. The feat was credited to Nieves, though was made possible by amazing outfield grabs by Jim Paciorek and finally by Robin Yount with 2 outs in the 9th inning. He was at the time, the second youngest to ever throw a no-hitter.
