First-and-Third Defense
Also known as: 1-3 defense, runners at the corners
First-and-third defense is the set of defensive schemes used when runners are on both first and third, designed to prevent the runner on third from scoring. At the same time, still trying to get an out.
The first-and-third situation is one of the most strategically complex in softball. This is because the offense can run on the pitch. This forces the catcher to choose between throwing through to second (risking the run from third scoring) or cutting the throw (catching the runner in a rundown but allowing the steal of second). Teams have multiple defensive calls. This means cut the throw, let it go, fake it. This means and the correct choice depends on the score, the speed of the runners. The inning.
Before every pitch with runners at the corners, confirm the defensive call verbally with your teammates. This means knowing the scheme eliminates the hesitation that causes breakdowns at game speed.
Vary your first-and-third calls game-by-game and even within a game. This means using the same scheme on every first-and-third situation allows smart offensive coaches to time your reaction and exploit it with a predictable run.
Example
Runner breaks for second. The catcher throws to the shortstop cutting position who immediately pivots home as the runner on third breaks on the throw, catching her in a rundown.
How it shows up on video
Film the entire defensive play from a center-field angle to see all four players (catcher, shortstop cutoff, third baseman, first baseman) and track who moves correctly when the runner breaks. A botched first-and-third defense shows the shortstop late to the cutoff position, the third baseman failing to crash on a faked throw, or the catcher making the wrong decision based on the wrong pre-pitch read of the defensive call. Communication — visible in pre-pitch gestures — is the precursor to successful execution.
Common mistakes
- The catcher throwing on its own to second on every steal without reading whether the defensive call was to cut or let the throw go
- The shortstop arriving at the cut position a step late, giving the runner on third too long to evaluate the throw's trajectory before breaking
- Not communicating the defensive call clearly before the pitch, leading to infielders reacting to the play rather than executing a pre-decided scheme
- The offense successfully reading the defense's default call and exploiting the same first-and-third scheme repeatedly in the same game

Frequently asked questions
What is the safest first-and-third defense for younger players?
A straight cut scheme. This means the shortstop catches the throw and immediately looks the runner on third back. This means is simple, reduces risk, and gives younger infielders a clear decision tree.
When should you let the throw go to second rather than cutting it?
When the runner on third has a slow start, the runner breaking to second is fast and the steal would be impactful, or the game situation (late, close score) makes the out at second more valuable than protecting against the run.

- Catcher Throwing MechanicsCatcher throwing mechanics encompass the footwork, transfer, and arm action a catcher uses to quickly and accurately throw to a base to retire a stolen-base attempt or catch a runner off base.
- Corner Infield PlaysCorner infield plays are the defensive assignments and positioning of the first and third basemen when the short game is in play. This means charging bunts, reading the hitter's slap, and executing the correct throw to the right base.
- Stolen BaseA stolen base is the advancement of a baserunner to the next base on their own initiative during a pitch, relying on a quick jump, reading the pitcher's release, and superior speed over the catcher's pop time.
