I was on Instagram (boo) watching Mookie Betts talk to himself during a round of BP. There were two things that happened in the video (thanks @sweetspothitting for posting it). 

1. He sort of dictates the outcome before he takes the swing. Of course, this is hard to do, and we're talking about a guy who's hit as high as .346 during a season. But you can do the same thing off a tee.

2. He's kind to himself. He talks to himself like he would a friend. Most players I coach don't do this. They don't get the desired result and beat themselves up. So there's a coaching point for me there: when I hear a player using negative self-talk in the cage, I need to step in and correct it. 

Thanks for listening, as always.
