R1, no outs. B2 hits down the left field line. Runners never stop. R1 is thrown out at 3b. Is B2 scored a single or a double.
Off the bat, I thought it was a double all the way. I was surprised when R1 was thrown out, and it wasn't really close. Game was being played in a drizzle, and R1 slowed rounding 2b to keep from slipping.
B2 gets a single under the provisions of rule 10.06 Comment: The official scorer shall not credit the batter with a two-base hit when a preceding runner trying to advance from first base is put out at third base, or would have been out but for an error.
