What happened: David Hamilton advanced to second base in the 6th inning after Freddie Freeman could not hang on to the ball. The play put a runner in scoring position with no outs. The sequence unfolded in October postseason play.

Why it matters: A runner at second with no outs can score on a groundout, flyout or base hit, raising the cost of the missed out. The defense now must strand the runner to keep the score unchanged. In a close postseason game, that extra base carries late-inning weight.

What to watch: Watch whether the next hitters advance Hamilton to third or drive him in. The inning turns on keeping him from scoring.
