The New York Mets have a weapon, and that weapon's name is Jordany Valdespin. The 25 year old made his MLB debut last season and has been belting clutch homeruns ever since. In his brief career (117 games), he's blasted 6 pinch-hit homeruns in 58 plate appearances. That's 1 pinch-hit homerun for every 10 pinch-hitting opportunities. His pinch-hitting OPS is .842 and he's collected 14 RBI in that situation. Too bad he's not as amazing when starting a game.
