The Red Sox did not call up right-hander Aaron Cook by 12:01pm ET tonight, thus activating the opt-out clause in his contract according to WEEI.com's Alex Speier. Cook has 24 hours to exercise the opt-out, then the team would have 48 hours to respond by calling him up or trading him.
Speier reports that the Red Sox will likely work out an agreement with the 33-year-old to keep him on the Major League roster, but there is no formal agreement in place at this time. Boston sent Lars Anderson to Triple-A after Tuesday's game, creating an open 25-man roster spot. The Red Sox would need to clear a 40-man roster for Cook, however.
The long-time Rockie has pitched to a 1.89 ERA with 13 strikeouts and 11 walks in 33 1/3 innings across five Triple-A starts. He signed a minor league deal with the Red Sox back in January. Manager Bobby Valentine had previous told reporters that if the team does add Cook to the roster, he will work out of the bullpen.
