SAN FRANCISCO — Shelby Miller pitched exactly one inning during the St. Louis Cardinals' 2013 postseason run to the World Series. He was portrayed by snarkier baseball fans as being a prisoner in the Cardinals bullpen, after a successful rookie season in which he won 15 games with a 3.06 ERA. A year later and Miller, 24, is unshackled during the 2014 postseason run. In fact, he's getting called on again in a crucial game.
