 Also, a batter-runner reaching first base on a play due to a fielder's error trying to put him out at first base or another runner out (as a fielder's choice) is not credited with a single.On a single hit to the outfield, any runners on second base or third base normally score, and sometimes the runner from first base is able to advance to third base.Depending on the location of the hit, a quick recovery by the outfielder can prevent such an advance or create a play on the advancing runner.
