To Do or Not to Do? I need an answer.....

Everyone this might sound like you at one point in your life but i need some help... I play baseball at my high school. I am a decent player. Im no high school recruit but i do believe i could go to the next level and play baseball. I have pretty nice grades. Im definetly going to graduate in my class' top 10%. The dilemma: My mom believes if i commited myself 100% to my grades then i would get a full scholarship for academics. But of course my dad encourages me to play baseball fully and rely on a baseball scholarship to carry me through college. ?? What do i do? Let my grades go and focus on baseball or commit myself totally to my grades. What would you do?
