Pitching Coach
Pitching coaches instruct their pitchers on pitching mechanics, pitch selection and preparation while also providing insight into the weaknesses of opposing hitters -- often with the help of video technology.
Pitching coaches can alter a pitcher's arm angle, placement on the pitching rubber or pitch selection in an effort to improve his performance or durability. During a game, the pitching coach assists the manager in making decisions pertaining to the starting pitcher and relief corps. He will also make occasional visits to the mound to help calm down or provide advice to a struggling pitcher.
