Yes, a runner may slide into any base at any time.
No, in Major League Baseball a base runner can slide into any base in any direction.
These are terms from baseball. To 'steal' is to advance one or more bases in a situation where the ball has not been hit: where someone has mishandled the ball, or during a pitch. A 'slide' is what players use when as a base runner they approach a base guarded by a defending player who has or is expected to shortly have the ball. If the defending player touches the runner before he touches the base, the runner is out, so the runner slides, usually foot first, toward the base, in an effort to get past the defender before he can be tagged.
Sliding is not required, but it is proven that it helps the batters get to the base faster.
The lead runner is the runner at the base closest to home plate when there is more than one runner on base. If there are runners on second base and third base, the runner on third base is the lead runner. If there are runners on first and second, the runner on second is the lead runner. If there is only one runner on base, there is no lead runner.
No. That would be an obstruction and the base-runner would be safe.
When a throw is made to a base where there is no force out, the throw has to be catchable to avoid the runner taking more bases on an overthrow or an error. So a throw must be placed some distance above the ground for the position player to make a play on the ball. This gives the base runner the opportunity to slide under the throw and touch the base with either his hand or foot. So I guess in short a slide is intended to get under the throw.
Yes
bases loaded means that there is a runner on 1st base, a runner on 2nd base, and a runner on 3rd base, all of the bases.
Yes you can slide into first base. It has been done in Major contention games where every out counted. I.E. game 5 or 6 or 7 of a world series, division series, or the like. 9th inning. It is not comonly see because it is usually your close or you out when you hit the ball.
The player who passed another on the base paths is out, the runner that was passed can continue to run to the next base.
Yes. The fielder covering the base does NOT have to tag the runner. The runner is forced out when the fielder steps on the base before the runner can make it back. Got that.
