Running Through First Base
Also known as: running through first, run through first base, overrunning first base, overrun first base, sliding into first base, running out a ground ball, running out of the box
On a ground ball, run hard through first base instead of slowing down or sliding. Touch the front of the bag and keep sprinting a few steps past it. The rules let a batter-runner overrun first and come back without being tagged out, as long as he returns right away and makes no attempt to run to second.
Official Baseball Rule 5.09(b)(11) says a runner is out if he fails to return at once to first after overrunning or oversliding it, and if he attempts to run to second he can be tagged out. This protection covers first base only. Umpires judge an attempt by what the runner does, such as turning and starting toward second, not by which way he turns.
Run through the base as if it were ten feet farther away. Hit the front edge with whichever foot arrives, and do not leap or lunge at it. After crossing, break down, look for an overthrow and listen to the first-base coach.
Most coaches teach running through the bag on a close play. A slide or dive into first is mainly a way to avoid a tag, such as when a throw pulls the first baseman off the bag toward home. Little League's rule FAQ says a batter-runner is not penalized for sliding into first. But a head-first slide while advancing is an out in Majors and below.
Tips by skill level
In practice, put a cone about ten feet past first base and sprint to the cone on every ground ball. Touch the front of the bag on the way.
After crossing, take two or three gathering steps and pick up the ball and the coach at the same time. If the throw gets away, you are already balanced to turn and go to second.
Example
A 12-year-old hits a slow roller and eases up just before first, and the throw beats him by a step. His coach has the team run through a cone set ten feet past the bag in every drill. In the next game the same play ends with him safe by half a step.
Why it matters
Close plays at first are decided by fractions of a second. Running hard through the bag, instead of easing up or lunging, turns some of those outs into hits and puts pressure on the defense.
Common mistakes
- Slowing down in the last few steps to land on the bag
- Leaping or lunging at the base instead of running through it
- Diving head first into first on an ordinary close play
- Turning and starting toward second after crossing the bag, which ends the protection
Frequently asked questions
Should you run through first base?
Yes. Run hard through the front of the bag and a few steps past it. The rules let you overrun first and come back safely as long as you return right away and do not try to run to second.
Is it better to slide into first base?
Most coaches teach running through instead. Save a slide or dive for avoiding a tag, such as when a throw pulls the first baseman toward home.
Can you get tagged out after overrunning first base?
Only if you do not return at once, or if you make an attempt to run to second. Turning toward fair territory alone is not an out; it is the move toward second that ends the protection.
Which way do you have to turn after running through first?
The rule names no direction. Turning toward foul territory avoids any doubt, but umpires look for an attempt to advance, not which way you turned.

- SlideA slide is the controlled fall a baserunner uses to reach a base beneath a tag, to kill momentum at the bag, or to avoid a collision with the fielder covering it.
- Baserunning ReadA baserunning read is the split-second decision a runner makes based on what the ball does after contact — whether to advance, hold, or retreat.
- Drag BuntA drag bunt is a bunt started while already moving toward first base, usually by a lefty. It aims to beat out a hit, not sacrifice an out.
- Stealing BasesTo steal more bases, win the race before you start sprinting. Take a lead you can safely get back from, learn each pitcher's first move to the plate, and go the instant he commits home. Push off with a quick first step, run straight at the bag without looking back, and slide early to the side away from the tag. In Little League Majors and younger, runners cannot leave until the pitch reaches the batter, so the jump comes from reading the pitch instead.
