Thanks, everyone for their comments. Will continue to work with our 2nd basemen.. Biggest challenge is getting them to think about what they need to do before each pitch. Every time the ball is hit, there's a split second delay as they process things. That's why they are slow to the bag. Happens even if I remind them right before the pitch to cover a bag. But again, it's rec, so they're learning.
As they get it wrong and you calming talk to them, they'll get it. It'll come, just be patient.
