Gameplay idea
 

After I have started a game I like to use the keyboard/keypad to play out the game until I need the mouse to make substitutions or strategic decisions. I am able to play this way until there is an option for the runner to tag up and take the next base. To do this I have to use the mouse. My suggestions is to have the option to press a key, such as Y/N, to advance the runner. This would make it easier for me and especially laptop users to avoid using the mouse to answer this query.

Absolutely need this option. Even in the menus when making changes to the line up. It asks Yes/No and you need the mouse to click on one of the buttons. The Y or N would be much better.
