This is always the BU's play back into first (in a 2-man system). BU should be reading the BR as well as having an understanding where the fielders and the ball is. If the BR makes a hard turn, the BU should be prepared to take the BR into 2nd. If the BR slams on breaks and there is a play back into 1st, the BU should drop step back in the direction of 1st and stop in the cut out for the play. This type of play is exactly why we don't "stare down" batter runner touches of first. If the BU is simply looking for the touch and only watching the runner, the BU may miss the backdoor play.
I try to let the play dictate what mechanics to use. Remember that our "safe mechanic" has many meanings....."Safe", "No catch", "that's Nothing", "balls in play" etc. To everyone else (Players, Coaches, fans) , safe mechanic only looks like safe. So I try to use it only when the situation calls for it. - On DK3 I will give my swinging strike Mechanic (pointing strike mechanic) with arm extended. - If it is unclear to the off. or def. that the ball was dropped (i.e. short hop), i will also give a verbal "No Catch" - I take a read step right or left as needed to see the possible tag attempt. - If TAG is made, I give a verbal "On the tag" and ONLY give my OUT mechanic - If BR runs to first or a TAG is attempted and MISSED, I will give the SAFE mechanic. - If no TAG attempt is made, and Batter does not attempt to acquire 1st, I will leave my right arm extended (pointing strike mechanic) until runner steps out of the dirt circle....then give my OUT mechanic Here is a video of me using this method....
Stop watches are also needed for between inning timing. Some of the larger Div-1 schools are installing pitch clocks but all do not have them so a stop watch is needed. I also use them in games when there is no between inning or pitch clock rule being enforced. This helps me determine if the crew is allowing two much time between innings. Anything around 90 sec. is good. Anything above we need to pick up the pace between innings.
