4 Man Mechanics - Pressure @2nd base

[UmpTTS43]

If we are all still refering to the original OP, the defense is playing in, we are behind them, close to or on the baseline, preferably in the "deep B" position. Since the D is in, any ball to the infielders that is fielded cleanly is more than likely going to go home, then possibly to 1st for the DP. If the ball is muffed, the play will likely go to first. If the ball stays in the infield, there is no reason for U2 to "bust in to the working area." There will be no rotations so the only responsibility U2 has is at 2nd base. Since all of the action is originating in front of him, it is acceptable, and easier, to position himself outside the basepath for any possible play and looking for R1 to touch 2nd. That way, you are not crossing paths with any infielder going back. If, for any reason, the ball happens to end up in the outfield on an overthrow, you can then come into the cutout area for any subsequent play. I could see myself going into the cutout area on the secondary throw to 1st on the DP, after R1 has rounded, all the while keeping my eye on the ball.
