Dave Koslo - 1951 Bowman

George Bernard “Dave” Koslo (born George Bernard Koslowksi 1920-1975) was the only pitcher to lead the National League in ERA (2.50 in 1949) without recording a single shutout for the season. The New York Giants purchased Koslo’s contract from the Milwaukee Brewers in 1941 and he debuted in the rotation that season. Dave spent 1943-1945 in the military during World War II and returned to the Giants rotation in 1946. Unfortunately, he led the National League in losses that first season back as well as giving up a league lead in hits (251) and earned runs (107) facing a league-high (1,136) batters. He enjoyed a 12-year career in the Majors with the Giants (1941-1942, 1946-1953) and won ten or more games in six of his ten seasons in New York, but also played for the Baltimore Orioles (1954) and the Minnesota Twins (1954-1955). Dave pitched in relief during the Giants 1951 battle with the Brooklyn Dodgers for the National League pennant, but went 1-1 in the World Series against the eventual champion New York Yankees. In 12 seasons as a Major League pitcher, Dave Koslo went 92-107 with 606 strikeouts, 74 complete games, 15 shutouts, 22 saves and a 3.68 ERA in 348 appearances.
