Dave Koslo (1941-1953)

Wins Above Replacement: 16.9

Koslo played ten seasons for the Giants; serving in World War II from 1943-1945. His best season came in 1949, where he went 11-14 with a league leading 2.50 ERA, and a WAR of 5.9. He never won any awards and only had three winning seasons in his career. Despite this, he was always viewed as a player who was better than the statistics show. Think of him as the original Matt Cain, suffering tough breaks, and receiving little run support.

Overall, in ten seasons as a Giant, Koslo went 91-104 with a 3.69 ERA in 1559.2 innings. Although it may seem odd to rank him above a Hall of Famer, remember, these rankings are based off of WAR.
