Bryan Edmund "Moose" Haas (born April 22, 1956) is a former professional baseball player who pitched in Major League Baseball (MLB) from 1976 to 1987. He appeared in the 1982 World Series as a member of the Milwaukee Brewers.
Haas initially signed a letter of intent to play college baseball at Clemson[1] before being drafted in the second round of the 1974 Major League Baseball draft by the Brewers.[2]
On April 12, 1978, Haas struck out 14 New York Yankees, including Reggie Jackson 4 times, breaking the record for strikeouts in a single game for the Brewers. This franchise record stood for 26 years until it was broken by Ben Sheets.[3] In 1983, he led the American League in pitcher winning percentage (.813) with 13 wins and 3 losses. Haas spent the first ten seasons of his career in Milwaukee before being traded to the Oakland Athletics in 1986 for Steve Kiefer, Charlie O'Brien and two minor league players.[2]
The 6-ft., 180-lb. Haas publicly stated that his father gave him that nickname upon birth: "My father gave it to me when I was born. I wasn't that big, only seven and a quarter pounds, but I guess I looked to my father like I was going to be big. It didn't work out."[4]
