Mechanic - Help from Plate on Foot Pull

[BayouUmp]

I had plate the other night with 2 outs and close play @ 1B. BU is set, sees the play, then yells "FOOT" and points to me.

Is this the proper way to ask for help? I expect to be pointed at for help, not "FOOT" yelled at me.

I was @ the 45-foot line and did indeed have a pulled foot, but this confused the defense..."What did he say?" and they started trotting off the field.

In pre-game I said 'look' to me for help on a foot-pull.
