I think there are varying levels of premeditation here. On a play at the plate, you really have a split second to decide what you're going to do, and how you're going to do it. If the catcher doesn't yet have the ball, or the throw is off line, or some other miscue happens, you're obviously going to let up. But if the ball arrives on time and the catcher is blocking the plate, you have to decide -- in a blink, basically -- if you're going to go over, under, or around him. At a certain point, I think it's a reflex, bang-bang play; you don't necessarily have time -- when you're running full blast and 10 feet from the plate -- to say, "Well, it's only spring training, so maybe I should let up." The Shelley Duncan play at second base was another matter entirely. From the time he left first base, he obviously had every intent of spiking the guy. It wasn't even close. It was just a cheap play. Gomes probably went overboard, but he gets points for standing up for teammate (albeit in a slightly rampaging way).
