Aaron Cook’s rehab assignment for a broken finger was scheduled to consist of three starts, but instead he’s already pitched four times and Thomas Harding of MLB.com reports that the Rockies “have asked” him to make at least one more start at Triple-A.
Barring any further changes Cook is on track to rejoin the Rockies’ rotation on June 8 against the Padres, which would be his first game action in the majors since September 8 of last year.
Jim Tracy told Harding that the Rockies want Cook to increase his stamina, but his arm must be pretty well stretched out given that he threw 99 pitches Sunday. The bigger issue would seemingly be the six runs he allowed in 7.2 innings against Triple-A hitters.
Pitcher David Phelps has a torn UCL and will undergo Tommy John surgery, ending his 2018 season, the Mariners announced on Wednesday. Phelps was making brief one-inning stints in the Cactus League as he worked his way back from a procedure to remove a bone spur from his elbow last September. He said he felt the ligament tear on his final pitch against the Angels in his March 17 appearance.
Phelps, 31, was expected to set up for closer Edwin Diaz. The right-hander, between the Marlins and Mariners last season, posted a 3.40 ERA with a 62/26 K/BB ratio in 55 2/3 innings. He and the Mariners avoided arbitration in January, agreeing on a $5.55 million salary for the 2018 campaign. Phelps will become eligible to become a free agent at the end of the season.
As the Mariners noted in their statement, the expected recovery period for Tommy John surgery is 12-15 months, so this very likely cuts into Phelps’ 2019 season as well.
