Agree with things that Coach and Joe said. If a fielder makes a great play behind you, be one of the first to touch gloves with him at the end of an inning. If you are a PO (non-hitting) be involved with the game when your team is up to bat. These intangibles count more than you think. Coaches are looking for a fit in addition to a good fastball. As others have chimed in, be yourself. Good luck to you.
