Red Sox vs. Yankees matchups
CatcherThe Red Sox offered former Dodger Russell Martin (left) a minor-league contract in the offseason. The Yankees got him with a big-league deal and the two-time All-Star not only has emerged as the starting catcher, but is off to fast start (.977 OPS in five games).
Jarrod Saltalamacchia has started four of the Red Sox' first five games and has done little so far to suggest he'll finally fulfill his promise.
The edge: Between Martin, ancient Jorge Posada, Francisco Cervelli (currently injured), and promising minor-leaguers Austin Romine and Jesus Montero, the Yankees have enviable depth.
