He's only coming up for everyday playing time, and he wouldn't be getting that. He's a fringy COF, and more than likely a first basemen. Also, Cave is more than capable of filling in for Buxton, offensively.
Not a good start at all from Hill. Looked really good the first time through the order, but couldn't get the third out. Not the start you wanted out of him. Hopefully rust is part of the reason
