He’s Corey Kluber, a former Cy Young-winner from Birmingham, Alabama who, for some completely incomprehensible reason, spends his winters in Winchester, Massachusetts (ohhhh, how fancy!)
The Sox signed him to a one-year, $10 million deal with a team option for a second year.
What position does he play?
He’s a pitcher, which you should have figured out from the “former Cy Young-Winner” thing.
Is he any good?
He was outstanding once (again, the Cy Young thing); an elite, big-game pitcher who never, ever walked anyone. His 2017 season was one of the single best seasons of the 21st century.
