Help!!

So I really really like this guy, we’ve both liked each other for over a month now, i asked him out through a baseball (I thought it was cute 😂) and i threw it to him while we were playing catch before my game. As he was reading it his mom walked over and he said “can I talk to you about it later?” And I said “yeah for sure” I would say the same thing in front of my mom lol, so anyway. I had to leave right after and we didn’t get a chance to talk, and he messaged me and said he was going to throw the ball back to me my next game day and it’ll have the answer written on it. his twin brother took the ball and gave it back to me, without him knowing. So that whole plan failed. We’re both really really shy and awkward people, we do like each other. And I’m planning on asking him out again tomorrow, I have a game and he will be there. I’ve been trying to figure out how to word it, I’m going to walk up to him and say “can I talk to you for a sec” and then ask him out privately. what do I say? How do I word it? I’ve been stressed these last two days because I physically don’t know what to say. I’m worried I’m gonna stutter and make a fool of myself 💀😂 someone please help me!!
