After spending 1993 in the minor league system for the Kansas City Royals, Mike Kingery was signed in the offseason by the Colorado Rockies. In one of the most shocking seasons in Rockies history, Kingery would come out of nowhere to not only play a key defensive role in the outfield, but also post a .349/.402/.532 slash line in the strike-shortened 1994 season. That .349 batting average is the eighth-highest single-season mark in Colorado history.
And before you start talking about Kingery hitting at altitude and this being a classic example of a ballplayer flourishing at a mile high, check the statistics.
