BOSTON, MA - The Boston Red Sox today placed right-handed pitcher Rick Porcello on the 15-day disabled list (retroactive to July 30) with a right triceps strain. To fill his spot, right-handed pitcher Ryan Cook was added to the active major league roster. Cook will wear No. 46 and will be active for today's series finale against the Tampa Bay Rays at Fenway Park beginning at 1:35 p.m.

Porcello, 26, has started 20 games for Boston this season, going 5-11 with a 5.81 ERA (74 ER/114.2 IP) and 92 strikeouts compared to 27 walks allowed. He last pitched on Wednesday, allowing five runs over 2.0 innings in his 200th career start. Prior to that outing, the Morristown, N.J. native allowed two or fewer runs in three consecutive starts from July 8-24, posting a 2.50 ERA (5 ER/18.0 IP). Originally a first-round selection (27th overall) by the Detroit Tigers in the 2008 June Draft, Porcello has registered a 4.45 ERA (587 ER/1,188.0 IP) with 747 strikeouts in 204 career major league appearances (200 starts) between the Tigers (2009-14) and Red Sox (2015).

Cook, 28, was acquired from the Oakland Athletics on Friday in exchange for a player to be named later or cash considerations. He has spent the majority of the year with Oakland's Triple-A Nashville affiliate, going 4-1 with eight saves, a 4.05 ERA (15 ER/33.1 IP), and 26 strikeouts in 30 relief outings. In four major league appearances for the A's from April 26-May 2, he went 0-2 while allowing five runs in 4.1 innings. Cook was a member of the 2012 American League All-Star Team. That year, he went 6-2 with a career-high 14 saves, a 2.09 ERA (17 ER), and 80 strikeouts in 73.1 innings over 71 relief appearances. The California native is 13-12 with 17 saves and a 2.93 ERA (66 ER) in 212 career major league outings, all in relief, between the Arizona Diamondbacks (2011) and A's (2012-15). Originally selected by Arizona in the 27th round of the 2008 June Draft, he has recorded 207 strikeouts in 202.2 career big league innings. Over the past three seasons, from 2012-14, he ranked sixth among AL relievers (min. 175.0 IP) in opponent batting average (.198) and seventh in ERA (2.60).
