Angels reliever Mike Morin is 25. Over the last three seasons, he has appeared in 167 major league games. Most of his appearances have gone well. Some have not.
The ones that don’t go well stick with him more than most, and he realized over the off-season that to be successful he needs to get past the setbacks quicker. Repeated failure over one two-week stretch in May gave him stress and discontent.
His off-season goal was not to improve any specific aspect of his pitching, but rather his ability to accept failure. And he is confident he has improved.
