Does He Like Me??????! PLEASE HELP! Im clueless...?

Okay so there is this guy and he is on my brothers baseball team. I really really like him more than any other guy Ive ever liked. Okay so I am super shy around guys and he is super shy around girls. We dont talk its just all in the body language. I know you are probably thinking how in the world can i like somebody that much without talking to him. I just have that feeling that Ive never felt before in my life when I see him. I dream about him EVERY night and he is in every single one of my dreams. I dream that I tell him I like him and I dream that he tells me he likes me. One time i dreamed that we were hiding under a table together lol :). Im 15 and he is 1 year younger than me. Anyways I go to his practices and games and I always catch him looking at me. Every time I look his direction he looks away. One time we locked eyes and smiled at eachother. Everytime something funny happens, he looks at me to see if Im laughing and i am. One time he threw a water bottle at the trashcan in the dugout when he was about to go out on the field and he missed big time so I looked back and we looked at eachother and he smiled at me. Weve made some small talk like one time he asked me what time it was and I told him but after that he didnt say anything or look at me. He was sitting behind me before a game. I tend to avoid the guys I like sometimes because Im shy and so I will talk to some of the other guys because I consider them friends but I dont want him to think I like them at all. I noticed he didnt look at me as much when I started talking to the other guys and I think he thinks I dont like him. You are probably going to say for me to just tell him I like him but Im too shy and i dont know how. If I message him on facebook that makes it seem like Im not serious about him or Im just like every other girl and I dont really care. I can never build up the courage to talk to him in person. I would do anything to be with him its just I need advice and encouragement. Does he like me? What should I do? I only have a couple weeks left before baseball season is over.... :( And yes I posted this question a few minutes ago but I only got like 2 answers. Please help me!
