Ryan Cook (back) tossed a 1-2-3 inning Sunday for the Mariners' affiliate in the rookie-level Arizona League.
It was his first rehab appearance, and the reviews were positive. Cook, out all year due to a severe lat strain, could become an option for the Mariners' bullpen after about two more weeks of minor league games. He was a terrific reliever for the A's before injuries threw his career off track in 2014. Jul 11 - 2:34 PM

Ryan Cook (back) will begin a rehab assignment with the Mariners' Arizona Rookie League affiliate on Sunday.

Cook has been out all season with a severe lat strain. It's unclear how many rehab appearances he might need, but it will obviously be a decent-sized number.

Ryan Cook (back) has been throwing well at extended spring training, per manager Scott Servais.

Cook was placed on the 60-day disabled list in mid-March with a severe lat strain. He's thought to be ahead of fellow Mariners reliever Evan Scribner, who is also sidelined because of a lat strain. Cook could become an option for the Seattle bullpen in June.
May 10 - 10:20 PM

Mariners placed RHP Ryan Cook on the 60-day disabled list with a right lat strain.

The 28-year-old right-hander was a longshot to crack the M's bullpen this spring, and they needed a roster spot with Saturday's signing of Rob Brantly, so to the disabled list he goes. Expect him to work his way into the bullpen mix at some point during the upcoming season.

Ryan Cook is suffering from a lat strain.

It was initially called a sore back, but Mariners skipper Scott Servais revealed the true diagnosis on Wednesday in camp. Cook is almost certainly going to open the 2016 season on the 15-day disabled list. He was a longshot to crack Seattle's major league roster anyway after yielding 18 earned runs in 8 2/3 innings last summer between Oakland and Boston. The 28-year-old right-hander's once-promising career has been completely derailed by injuries.

Ryan Cook is being slowed by a sore back.

It doesn't sound like anything major, but any sort of physical setback will hurt Cook's chances of cracking the Mariners' bullpen for Opening Day. He threw just 8 2/3 innings at the major league level in 2015 due to forearm issues and surrendered 18 earned runs in that limited exposure. The right-hander had a shiny 2.60 ERA in 190 2/3 innings with the A's between 2012-2014.
Mar 7 - 10:20 AM

Mariners signed RHP Ryan Cook to a one-year contract.

While it was originally reported that Cook garnered only a minor league contract, the deal actually places him on the 40-man roster. Cook held a shiny 2.60 ERA in 190 2/3 innings with the A's between 2012-2014, but forearm issues have derailed his career. The 28-year-old right-hander surrendered 18 earned runs in 8 2/3 innings with Oakland and Boston in 2015.
Jan 7 - 6:08 PM

Cubs non-tendered RHP Ryan Cook.

The Cubs claimed Cook off waivers from the Red Sox in early November. He was eligible for arbitration, though, and Chicago opted to let him hit free agency. While the right-handed reliever was rocked for 19 runs in just 8 2/3 innings at the major league level in 2015, he held sub-3.50 ERA's in three seasons with Oakland prior to his recent struggles. Any clubs looking to sign him will likely lean more on those numbers than the disastrous ones he posted during the 2015 campaign.

Cubs claimed RHP Ryan Cook off waivers from the Red Sox.

The Cubs are hoping Cook can bounce back after he held an 18.69 ERA over just nine relief appearances for the A's and Red Sox. The reliever posted a 2.60 ERA with over a strikeout per inning in the three seasons prior to that.

Red Sox recalled RHP Ryan Cook from Triple-A Pawtucket.

The Red Sox acquired Cook from the A's on August 1. He held a 4.05 ERA, 1.38 WHIP and 26/14 K/BB ratio across 33 1/3 innings with his former club. In 9 1/3 innings with Triple-A Pawtucket, he had yet to allow a run. While Cook likely won't be seeing any high-leverage work, he's not the worst you could do for a September call-up.

Red Sox optioned RHP Ryan Cook to Triple-A Pawtucket.

Cook was pounded for five runs in two-thirds of an inning in Saturday's 22-10 win over the Mariners. The 28-year-old right-hander may get another try come September.

Red Sox recalled RHP Ryan Cook from Triple-A Pawtucket.

With Koji Uehara set to miss the rest of the season with a wrist fracture, the Red Sox needed another arm in the bullpen. That would be Cook, who they acquired on August 1 from the A's. With Oakland's Triple-A squad, he held a 4.05 ERA, 1.38 WHIP and 26/14 K/BB ratio across 33 1/3 innings. He won't see closing or setup duty, but could be in line for some holds if he earns the Red Sox trust in lower leverage situations.

Red Sox acquired RHP Ryan Cook from the Athletics for a player to be named later or cash considerations.

The 28-year-old right-hander and former closer of the Athletics has spent the majority of the 2014 season at Triple-A Nashville where he has posted a 4.05 ERA, 1.38 WHIP and 26/14 K/BB ratio over 33 1/3 innings. He's a nice low-cost gamble for the Red Sox.

Alex Speier of the Boston Globe reports that the Red Sox have acquired Ryan Cook from the Athletics.

They're sending cash to the A's. Cook has spent almost all season at Triple-A, posting a 4.05 ERA. The A's likely would have non-tendered him this winter, so they decided to pick up a little cash for him now.

Athletics optioned RHP Ryan Cook to Triple-A Nashville.

Cook was hammered for five runs over 4 1/3 innings during his week up with the big club. Chad Smith has taken his spot in the bullpen.
