Cook (back) threw a perfect inning in the Arizona Rookie League on Sunday in his first rehab game, Greg Johns of MLB.com reports. Cook saw his first live action since being placed on the 60-day DL in early March and managed to retire the side without surrendering a base runner. The 29-year-old will be eligible to return shortly after the All-Star break and will look to get back to his 2014 form that saw him post a solid 3.42 ERA in 50 innings of work for the A's.
Cook (strained right lat) will begin his rehab assignment for Peoria in the Arizona League on Sunday, Bob Dutton of the Tacoma News Tribune reports. Cook has not pitched at all in 2016. If he can successfully complete his rehab without any setbacks, he could be a nice addition to a Mariners bullpen that has struggled over the past couple of weeks leading up to the All-Star break. Cook, who had a great run as a reliever for Oakland from 2012-2014, will look to regain his form after a very disappointing 2015 with the Athletics and Red Sox organizations.
Cook (back) was placed on the 60-day DL by the Mariners on Saturday. Cook was expected to open the season on the DL, but the 60-day DL means he is going to have to wait a long time before he can see the field. The move is to make 40-man roster room for the newly acquired Rob Brantly.
Cook (back) will likely open the season on the disabled list, the Tacoma News-Tribune's Bob Dutton reports. It is not clear how long Cook's back injury will keep him sidelined, but this will open up opportunities for Tony Zych and Joel Peralta at the outset of the season. When Cook is healthy he should occupy a middle relief role.
Cook has a strained back that is expected to keep him out more than two weeks, the Tacoma News Tribune reports. Cook faces tough odds to land a bullpen spot. Missing significant time probably seals his fate.
