Baseball Fastpitch


What to know before you register: Mustang is the entrance to competitive baseball and fully kid pitch.  This is the first division where no friend requests are honored. ALL players must participate in assessments their first year in division, second year players can opt to "return to team" or "return to assessments". Assessments happen in February and Coaches will draft players mid February. Teams will be announced around the coaches meeting (end of Feb). Players are assessed and drafted to offer a competitive league without stacked teams. Weekdays and and times can be found on the right panel of this page. This division has play-offs and an All Star Game at the end of the season. 

MUSTANG 10U (ages 9-10): 
 Begins the player's training in the complete game of baseball. Players pitch with introduction to leading off and stealing on 60-foot base paths.

MUSTANG 10U™ LEAGUE begins PONY Baseball belief that rather than change the rules of Baseball to make it possible for young people to play the game, it is more logical to change the size of the diamonds, to adjust them to the physical potential of the players.

Use of diamonds matched to their capabilities permits younger players to play in the same proportionate position as the Major Leaguers and to make the same plays as a Major Leaguer. The double play, the squeeze play, the force play, etc. all become probabilities instead of remote possibilities.

Beginning with MUSTANG 10U™ LEAGUE Baseball, the players are playing real baseball in accordance with The Rules of Major League Baseball as well as specific PONY rules that are in place to supersede the MLB rules where appropriate such as pitching, substitution, re-entry, etc. With scaled down bases and pitching distances, players react quite favorably to the greater challenge of the game and have little difficulty mastering the transition.
