A runner takes a lead from second. The shortstop comes in from behind as if there will be a pick off throw, but then cuts between the runner and the bag (cutting close to the runner) and moves in front of the runner to block his view of the pitcher. The second baseman then runs to the bag and takes a pick off throw from the pitcher. While there was no overt contact between the shortstop and the runner, the clear purpose of having the shortstop cut between the runner and the bag is to cause the runner to stop returning to second. (Generally the runner starts moving back toward the bag when the third base coach warns of the shortstop coming in.)
Q.1 - The Rule. Is this obstruction under NFHS Rule 8-3, Art. 2? Contact is not required for obstruction, such as when a first baseman stands in the baseline and causes the runner rounding first to tak a wide turn on his way to second? The clear purpose of the shortstop's movement is to obstruct the runner's return to second, and the shortstop does not have the ball and is faking a pickoff. I'm inclined to say yes and award third base to the runner.
Q.2 - Practical Reality. Realizing that the call involves some judgment on the umpire's part, isn't the best move for a runner who sees the shortstop start to cut between him and the bag to run back to second with almost certain contact with the shortstop? In that case, the contact between the shortstop (who doesn't have the ball) and the runner virtually mandates an obstruction call, so long as the runner doesn't go out of the baseline to initiate contact.
