Moose Haas was drafted out of Franklin High in Baltimore by the Milwaukee Brewers in the 2nd round of the 1974 MLB Draft. He was a dominant pitcher in high school and quickly moved through the Brewers farm system to debut in the major leagues in 1976 at just 20 years of age and earned a regular spot in the Brewers starting rotation the following season. Haas broke a Brewers team record with 14 strikeouts in a game on April 12, 1978. The record stood for 26 years until broken by Ben Sheets. At the end of spring training in 1986, Haas was traded by the Brewers to the Oakland A's in exchange for reserve infielder Steve Kiefer, catching prospect Charlie O'Brien along with minor league pitchers Pete Kendrick and Mike Fulmer. Haas pitched his final two seasons in Oakland before retiring. Over his career, Haas was 100-83 with a 4.01 ERA and pitched for the Brewers in the 1982 World Series against the Cardinals. His best season was arguably 1983 as he led the league with a .813 winning percentage by going 13-3 for the Brewers with a 3.27 ERA in 25 starts. Haas was inducted into the Maryland Athletic Hall of Fame in 1992.
