Runners advancing
 

It is FAR too easy for a runner to take third base on a ground ball. The impetus of this thread was a sharp comebacker to the mound, where the runner advanced. IRL, the pitcher would have looked the guy back to second before throwing to first. If after the throw, if the runner wanted to try, you would think this move would elicit a throw from first. I guess not.

I've seen instances of a grounder to THIRD, and the runner still moves up from second.

I know it may be to late for the first patch, but this is part of the larger baserunning problem discussed before.
