In my opinion, kershaw has the highest upside. He's a really solid high schooler with Huge Upside and projects as a top of rotation starter. Adam Jones is a five tool type player for the Mariners. I would say as far as upside, i would rank them like this.
Though, Bruce and Martinez are both great prospects. They both have alot of potential.
Is pushing for President Obama to pass a law requiring all citizens to be Chicago White Sox fans and make October 1st "White Sox Day" where we all dress as our favorite player. It maybe socialist, but I don't care.
