The 34-year-old Martinez is coming off a torn ACL, an injury that tends to end a catcher's career. The good news is that V-Mart still has a future as the Tigers' DH, but will remain eligible at catcher in most leagues after registering at least 20 games behind the plate in 2011. Statistically, Martinez should benefit from hitting behind Triple Crown winner Miguel Cabrera and monster masher Prince Fielder. An ACL roadblock didn't slow Adrian Peterson in a more physically demanding sport, but there's always considerable risk involved with drafting an aging player coming off a major injury. Martinez should repay that gamble.
