James Shields may have been given the nickname "Big Game," but his postseason track record over the last few seasons - especially this year - suggests it's a bit inaccurate. Instead, his counterpart for Game 5 of the World Series has been proving himself more deserving of such a moniker. Madison Bumgarner looks to move the San Francisco Giants within a win of a third World Series crown in five years Sunday night as he faces Shields and the Kansas City Royals. Shields has been the Royals' ace since coming over in a trade from Tampa Bay prior to last season, with 27 regular-season wins and a 3.18 ERA.
