We’re not going to pretend that this .400 tear John Buck is on will continue for any significant time. He is, after all, an all or nothing type, as his 120 career homers against a .236 career average indicates. His job is to handle pitchers and provide good defense. If he gets a few key hits as he has so far this year, highlighted in Saturday’s win over the Marlins, then all’s well and good. The Mets can’t rely on Buck to drive in four runs with a two-run double and a pair of sacrifice flies every game.
