I don't know if that prediction is very bold. Sale damn near won Cy Young on a team that won 63 games last season, and there aren't that many players on the planet (if any), let alone a rookie, who can add 20 wins to a team's record alone. The only truly bold thing about it is predicting ROY for Abreu, really. Rookies pop up into prominence out of nowhere seemingly every year.
Rock over London. Rock on, Chicago.
