When a batter hits safely to the out field and is thrown out at second is he credited with a single?
No, once you are tagged out you don't get credited with anything
if you are the one at bat. Now if another batter hits the ball and
there was already a man on base at first and he gets tagged at 2nd
base, then yes the man on 1st base would get the single from his
previous at bat If the batted ball was cleanly a base hit and he
was thrown out trying to advance past first base then the batter
would be given the hit corresponding to the last base the batter
reached safely. If the batter was thrown out at second, the batter
would be given a single. If the batter was thrown out at third, the
batter would be given a double. If the batter was thrown out at
home plate, the batter would be given a triple.
