This Stephen Strasburg guy

So I don't know if you guys have heard about him, but supposedly this Stephen Strasburg person is a good player of baseball.  I don't know much but he might be one of the outer people who stand in the grass?  No.  No he's a thrower.  He does the throwing.  Not just any throwing but the throwing that other people have to hit, you know the one I'm talking about?  Yeah that one, but whats pretty cool about him is his throwing is pretty hard.  And he's like accurate or whatever which I guess is good.  But yeah like I hear that when he throws most people try swinging and miss.  Or like they don't try swinging and then for whatever reason they are supposed to sit down after a few pitches with their other teammates.  Which I think is unfair.  Like sometimes when people don't swing at a bunch of the throws they get to go to first base and then other times they have to sit down.  And it looks like the dude in the black shirt behind him tells him which one to do, which is weird cause he's not even playing in the game, right?  But anyway I think these guys in black really like Strasburg, because for him they make all of the other guys sit down.  I guess Strasburg's dad must own a black t-shirt and facemask company.  Or maybe they don't like him, and that's why he has to stand in the middle on that patch of dirt, to keep him away from all of the other baseballers.  Could be that.  Anyway I just figured this being a group of enthusiasts of the game of baseball you may want to know about this thrower person because I don't think anybody else has ever talked about him before.  So yeah.
