I left it on pro difficulty and started a basic play now game, I picked the #1 team and went against the #30 team. Before the first pitch of the game I set all the sliders to the right for me, than all of the way to the left for the CPU. I finished a complete game, which was very painfull I might add, with at least 19 strikeouts and got no gamerscore out of it. I want to continue to get all 1,000 but I am unsure if I am doing something wrong. Please help me out!

You can't adjust the game sliders because that makes it a custom difficulty and not pro.
