The Chicago Cubs today claimed right-handed pitcher Ryan Cook off waivers from the Boston Red Sox. The club's 40-man roster now stands at 30 players.
Cook, 28, is 13-12 with 17 saves and a 3.43 ERA (79 ER/207.0 IP) in 217 major league relief appearances in all or part of five major league campaigns with Arizona (2011), Oakland (2012-15) and Boston (2015). He has struck out 210 batters in 207.0 innings while walking 89 and allowing only 13 home runs. Cook has limited foes to a .217 batting average against and has held right-handed hitters to only a .190 batting average, .262 on-base percentage and .272 slugging percentage.
The 6-foot-2, 217-pound Cook broke into the big leagues with Arizona in 2011 before being traded to Oakland that offseason. In his first full major league campaign, Cook made the 2012 American League All-Star Team and went 6-2 with 14 saves and a 2.09 ERA (17 ER/73.1 IP) in 71 outings with the Athletics. He followed up by going 6-4 with two saves and a 2.54 (19 ER/67.1 IP) in 71 appearances a year later. Cook was slowed by injuries in 2014 but still posted a 3.42 ERA (19 ER/50.0 IP) in 54 big league outings.
Cook split most of the 2015 season between Oakland's Triple-A Nashville and Boston's Triple-A Pawtucket affiliates, combining to go 4-1 with nine saves and a 3.16 ERA (15 ER/42.2 IP) in 37 minor league outings. He made nine relief appearances in the majors between Oakland and Boston, going 0-2 with an 18.69 ERA (18 ER/8.2 IP).
A native of Clovis, Calif., Cook was selected by Arizona in the 27th round of the 2008 Draft out of the University of Southern California.
