Teamwork is everything in this baseball game!
When batting, click on one of the 9 squares to swing, timing your hit with the pitch. You can steal a base by clicking the helmet on the mini map and then the next base. While pitching, pay attention to the powerbar and click one of the squares to throw the ball. Click the bases on the mini map to throw the ball there.
