Name to Watch: Super prospect Mason Williams

One Yankee talent evaluator called 20-year-old Mason Williams a "true five-tool" player. Another said that he is the guy to watch shoot through the system.

Williams is the 20-year-old outfield prospect whom the Yankees are going to be asked to trade, but are unlikely to give up unless it is for a major -- I'm talking King Felix-level -- starter.

The Yankees selected Williams in the fourth round of the 2010 draft. They paid him way over slot, nearly $1.5 million, to sway him from going to South Carolina. So far, it looks like money well spent as Williams dominated A-ball, hitting .349 with an .863 OPS. He only hit three homers, but the Yankees think the power will come.

The Yankees will be asked about Williams this week, but it is highly doubtful they will deal him.
