Obstruction Penality

[manhong]

Summer ball playing pro rules. I was the plate umpire and my partner was the base umpire. Runner of second with no outs. The pitcher throws to the 2nd baseman and runner gets stuck in a run down between 2nd and 3rd. As he approaches 2nd base, a fielder obstructs the runner.

My question is whether or not the fielder should be awarded 2nd base or 3rd base??? My partner awarded him second base because that is the base he was attempting to reach when the obstruction occurred. However, in a run down, doesn't the runner get a base beyond the obstruction penality (in this case, would he get 3rd base)??? According to the pro rule book, 7.06 says "The obstructed runner shall be awarded at least one base beyond the base he had last legally touched before the obstruction." So did my partner get this wrong???
