There will be plenty good ones left. If you need a strikeout, try aiming a breaking pitch like a slider or curveball outside of the strike zone and let it drop in the zone for strike three. Warm up a relief pitcher when the current pitcher's stamina bar is in the yellow. Once a pitcher has no stamina left, he's tired and his breaking pitches will lose their movement. When in the field, do not use aggressive throws only use aggressive throws on potentially close plays.
Aggressive throws lead to more errors.
If you have two opposing runners caught in a rundown, concentrate on getting the lead runner out. When attempting to make a diving catch in the outfield, try and wait until the last possible moment before diving. If you're having trouble getting base hits, stick with the contact swing. It will improve your chances. The ball will jump off the bat with much more velocity.
