I've never understood the whole 'better footwork' argument (heard it alot about Costanzo as well), as I really don't understand what constitutes 'good footwork' or 'bad footwork' for a 2B (or SS or 3B for that matter). A 'footwork primer' would be appreciated (to the extent anyone has the time or inclination). Thanks!
I know some about 2b and 3b. The crossover step is the most important first move unless the ball is hit almost directly at you. For balls hit more directly, slide step. Never back up. Don't get your feet crossed when the ball is near you. Once you get to the ball, always leaning forward, glove low, you have to set the back foot to make the throw.
The turn at the base for a dp, if you have a decent arm, you can catch the ball with your front left foot on the base, jump and heave. I never could, left foot, base, catch, one step, plant right foot (sideways, or for the daring, back), then throw.
(eta: Some crazy sob is going to tell you catch the pivot with the back right foot on the bag and stride towards the runner for the throw. They can do that.)
Much more comfortable at 3d though. Hardly ever slide step. Cross step, esp towards the line, slow rollers, short choppy steps in and always end with your plant foot, (right foot) back.
