Many leg-lifting lefthanders have a habit of looking home if they're throwing over to first, and vice versa. However, what's the practical value of teaching this to your players?
It doesn't help a non-stealing R1--regardless, (A) Lean back and begin secondary after LHP commits fully to the plate.
It doesn't help a stealing R1--regardless, (B) Go on first move if the coach has given the steal sign.
Teaching R1s about LHPs' tendencies regarding throw overs is too much information, in my opinion.
Eliminate the gray areas for your players.
