2018 - Starters (Kingham, Henley, Shugart) BP (Parker Joe, Stevens, Elder, Bocchi, Sawyer) Kamron Fields (1.82) had a good year along with Jake McKenzie. Not sure they were no names, regardless they had good years.
Phil Haig's exit as a volunteer asst was necessitated by Huston saving Pierce by introducing him to Tulo. Would Haig have been kept otherwise, who knows ?
Like Pierce, Sean Allen's forte is recruiting - one of the best in college baseball. His coaching career has mainly been with hitters and infield, the exception when he first started his career as pitching coach/asst pitching coach at FIU for 3 years. His playing career was an infielder at UH.
Will the combination of Pierce/Allen as pitching coaches provide long term success ? Led the B12 last year with era of 2.93 (conf only). As of today (5.19) which is 4th in conference in what is playing out as year of the hitter conference wide.
The main role of a pitching coach, maybe equal or above mechanics, is to develop confidence. Sometimes you have to show trust in dificult situations.
