It bears repeating....
Confidence is an incalculably large part of success. The assurance a player will be in the lineup despite one or two "failed" outings contributes mightily to his ability to overcome short-term frustration and disappointment. The converse, that a couple of hitless nights or errors will cost a player an opportunity to start undermine future success.
The more John Mayberry and Dom Brown play, the more confident they are and the better they perform.
Count on it.
UPDATE: What was I thinking???????
