R1 on 1st base batter rips a line drive to SS who tries to double up R1 who is off the bag....when SS released the ball R1 had not made it back to the bag for tag up....ball is thrown out of play...i know runner get 2 bases from point of release but does going back and tagging up count as 1 base therefore he only gets 2nd? or does he get 3rd? Looking in rule book but cant find it...if you have rule No. please post it thx in advance
