First and third defense
A first and third defense is a prearranged play against runners on first and third base, set so the defense stops the run at the plate without giving up second base for free.
With runners on first and third, the offense is threatening a double steal: the runner on first goes, and the throw to second lets the runner on third score. The defense answers with a play called in advance, so everyone knows who covers what.
There are a few standard ways to defend it. The catcher can throw through to second and let the runner on third go, give up the run for the out, or fake the throw to hold the runner. Another option is for the middle infielder to cut the throw in front of second and throw home, or for the pitcher to step off and check the runner on third first.
The call depends on the score, the inning and the runner on third. With a one-run lead late the defense holds the run and plays for the out at the plate, and early in a game it may trade the run for the out at second. A call sheet in the dugout and a sign on the catcher's wristband tell the infield which version is on.
When to call it
- A fast runner on first and a slow runner on third, late in a close game.
- A catcher with a strong arm who can throw through to second and back the cutoff.
- Two outs, where giving up the run for an out ends the inning.
