The Padres love Carlos Quentin's bat—he hit 16 homers and had a .504 slugging percentage in 340 plate appearances last year—so much that they signed him to a three-year contract extension last summer. Perhaps they thought the National League was about to adopt the DH. This spring underscored the key problem with the signing: Quentin can't stay on the field. Since his breakthrough 2008 with the White Sox, he has averaged 108 games per season and just 768 innings a year in the field, about half a season. And with 10 days to go before Opening Day, Quentin hadn't played an inning of defense as he nursed his right knee back from the two surgeries he underwent in 2012. Given his history, age (30) and size (235 pounds), there's no reason to think he can carry the workload of an everyday corner outfielder. The Padres should look to trade him to an AL team so he can DH at least some of the time—perhaps the injury-riddled Yankees would swing a deal. In San Diego, Quentin can only be a part-time player.
