Boston Red Sox: Deven Marrero, SS, Arizona State

Grade: B

You can't blame the Red Sox for going with the safe pick with their first of three in the first round, and I'm sure they were happy to have him slide that far. He's hit tool is highly concerning and he'll never hit for much power, but he's a plus defender with a plus arm. He's an aggressive ballplayer who fits the Red Sox system. Then again, don't they already have a Marrero-like player in Jose Iglesias?
