We want our 2nd baseman with the ball "walking the runner" back to first with the 3rd baseman
keeping an eye on the runner at third.
C receives bunt defense sign from 3rd baseman, then calls a pitch-out and delivers a strong throw to the left side of 1st base.
P receives signal from 3rd baseman, waits for daylight between SS and runner, then throws to 2nd.
With a runner on base, what should the 3rd baseman do each time the 1st baseman throws to the pitcher?
Because it will force the 3rd baseman to make a longer throw and, if the ball rolls foul, will give the hitter another chance to swing the bat.
3rd Baseman reacts to hard-hit balls to his glove and his backhand side.
The LF fields the ball and throws to the 3rd baseman (cut-off man), who lets the ball go through to the plate or cuts it off and throws to the SS covering 3rd for a run-down play on the runner, who has broken around 3rd base.
3rd Baseman gets down on both knees, which forces him to get his hands out in front of his body, and fields grounders hit by the infield coach.
3rd Baseman, SS, Left Fielder, same play as above but with the coach hitting the ball to short left field and down the left-field line.
Whenever the back runner is being run down, the 3rd baseman must alert the defense to the man on third.
If, with two outs, the defender with the ball is running down the back runner and is within two feet of him when he hears the 3rd baseman call "four-four," he should try to tag out the runner before the front runner crosses the plate.
If the runner begins to creep down the baseline and can be picked off, the 3rd baseman will call "three-three.
