Are you asking about team tryouts in Victorville? Or how do tryouts work in general?

When and how are Victorville try-outs held. Sorry didn't mean to be so general.

Try these:

You might also stop by Hook Park and ask around. I would imagine they have a flier up. Generally, tryouts are over for this year, but there be some teams looking for players for ages 14 and above as noted in the flier above.

The players are given drills on fielding (groundball,flyball), batting, and baserunning. Then there will be scrimmage after. pitchers and catchers are grouped separately.

there will also be tests related to softball to see the athletes strength
