The Red Sox have placed Aaron Cook, Felix Doubront, and Andrew Miller on trade waivers, according to Nick Cafardo of the Boston Globe. Cafardo notes that while Doubront won't be going anywhere, Cook is a trade candidate.
In ten starts this season, Cook has a 4.58 ERA with 1.1 K/9 and 1.6 BB/9. The 33-year-old inked a minor league deal with Boston over the winter, worth $1.5MM prorated upon his promotion to the big leagues. The Red Sox waited until the 11th hour to call him up rather than trigger his opt-out clause, but ultimately putting him on the big league roster in early May.
