Bucs vs Nats...attempted advance toward 2nd?

[Dave Reed]

It was a correct call. The B/R neither overran nor overslid the base, both of which imply the runner is attempting to reach 1st base as his primary goal. Instead he was gauging whether he could try to advance to second.

Even under-educated fans who want an out called because a B/R "turned left" after overrunning 1st will notice that in this case the runner wasn't even remotely trying to beat the ball to the bag.

And, what do you suppose caused the defense to tag him?
