If this is the case, he'd get to second but the left fielder, as long as he saw what was going on, should be setting himself in-line with the throw, should it get past the first baseman, thus keeping the runner honest. If the groundball was to short or second, the story is different.

Just my take on the possibilities here.

I'll bet Fidel M. meant "right field line" and "right fielder" here.
