Fast fact: Hitting .330 (38 for 115) with .384 OBP at Fenway; 0 HR in 108 ABs at Yankee Stadium. Lowdown: Sox fans who trust their eyes will find it incredulous that one defensive metric (runs saved against the average) rates Alex Gonzalez’s shortstop defense (-3) slightly worse than Lugo’s (-1), but what is indisputable is that Lugo’s bat will be a major upgrade, assuming he is the player he was in Tampa Bay and not the miserable lost soul who was playing out of position with the Dodgers.
