 Biographical Information
Nicknamed "Juanchi", pitcher Juan Nieves went 19-1 with a 1.05 ERA in his career at Avon Old Farms High School in Connecticut. After graduating, he was signed by the Milwaukee Brewers in 1983 and scouting supervisor Ray Poitevint, scouting supervisor Felix Delgado and scout Tom Bourque.
Nieves was a mainstay in the Brewers' rotation from 1986 to 1988. On April 15, 1987, he threw a no-hitter against the Baltimore Orioles, becoming the second-youngest player in major league history to throw a no-no and so far the only Brewer to do so. However, his promising career was cut short when he suffered an arm injury the following season.
Nieves was a pitching coach in the New York Yankees organization from 1992 to 1996 and filled the same role in the Chicago White Sox chain from 1999 to 2007. In 2008, he was named the White Sox bullpen coach, working under respected pitching coach Don Cooper, staying in the position until the end of the 2012 season. In 2013, he was hired by the Boston Red Sox to be the pitching coach under new manager John Farrell.
Away from the diamond, Nieves played the role of "Fransico Delgado" in the 1999 movie For the Love of the Game.
