Pitching clinics

MGS pitching clinics are here.  This season they're open to all 8U through 15U players from beginner to advanced.  Signups open at 9:00am Tuesday, January 14th.

Beginner Pitching Clinics - 8U, 10U, 12U, and 15U Welcome!

MGS recently announced our intent to discontinue adult coach-pitch for 10U in 2021 (next season).   As a result, we're encouraging  8U players that are interested to start attending pitching clinics as soon as possible.  Likewise, all players that have had an interest in pitching can benefit from understanding the skills.  Sign up for these beginner sessions, hosted by MGS at Red Hill starting January 26th.

Sign Up!

Intermediate Advanced Pitching Clinic (10U-15U only)

Conducted at Bacich Community Center, these sessions are indoors and will happen rain, hail, or shine.  These sessions are limited to 5 pitchers per session.  There is no charge for these sessions, however, players are limited to 2 session sign-ups at any one time.  This is an investment in our players by MGS, therefor no-shows will not be tolerated and will result in suspension from attending these clinics for the remainder of the season.

Sign Up!
