The Phillies released righty Aaron Cook, according to a tweet from the team. The team's other choices were to add him to the 25-man roster or pay a $100K retention bonus to send him to the minors.
Cook, 34, posted a 5.65 ERA, 1.9 K/9, 2.0 BB/9, 1.44 HR/9, and 58.6% groundball rate in 94 innings for the Red Sox last year. He signed a minor league deal with the Phillies in mid-January. Cook still keeps the ball on the ground, but it's hard to survive with so few strikeouts.
