Impact: This might be due more to a trickle-down effect than anything else, as Jose Molina is doing the catching while Jorge Posada is actually the DH. Newly-acquired first baseman Richie Sexson has outproduced Giambi against left-handed pitching this season and he'll likely start at first base against southpaws going forward. If Posada is healthy enough to catch later on this season, Giambi could still play against lefties as the DH, since Hideki Matsui is likely out for the season.
