The running lane rule to first base

Next time you’re at the field, take a look at the chalk on the way to first base. About halfway down the line, a second line shows up three feet into foul territory and runs all the way to the bag. That’s the running lane. Most young players have no idea what it’s for.

Once the batter-runner is in that last half of the line, he has to run inside the lane (both feet). If he’s outside it, in fair territory, and he interferes with the fielder taking the throw at first, he’s out. The ball is dead, and the runners go back.

The classic version is a bunt or a dribbler in front of the plate. The catcher fields it and throws, and the runner is straight up the line in fair territory. The throw hits him in the back, and he’s out.

And he’s out because he was somewhere he wasn’t allowed to be — not because the catcher made a bad throw.

Being outside the lane isn’t automatically an out, though, and this is where players and parents get confused. There has to be a throw, and there has to be interference.

If there’s no throw, there’s nothing to call.

A bad throw also doesn’t turn into interference simply because the runner was in fair territory. If the throw would have sailed anyway, the umpire isn’t going to bail out the catcher.

Of course, the runner is allowed to step out of the lane on his last stride to touch the base. The bag is in fair territory.

MLB widened the lane in 2024 so runners can use the dirt in fair territory, and your players saw it on TV. But Little League and high school didn’t change, and the old lane still applies to your team there. USSSA plays by the pro book, so at a USSSA event it’s worth asking which lane the umpires are using.

This is one we really only need to teach once. If you bunt it in front of the plate, get into the lane! Have you ever had a player called out on this one?
