#Mariners activate OF Franklin Gutierrez from disabled list. RHP Aaron Harang has been designated for assignment.— Seattle Mariners (@Mariners) August 26, 2013
Gutierrez has been on the disabled list since June 25th, suffering from a strained right hamstring. He has played in just 18 games for the Mariners this season, hitting .267/.290/.583 in 63 plate appearances. The Mariners hold a 2014 club option for $7.5 million on him, but it is unlikely to be picked up.
Harang has been worth over 20 wins above replacement in his career, but his tenure in Seattle has not gone well. After putting up a strong 2012 campaign, Harang was traded to the Colorado Rockies for Ramon Hernandez this past April. However, he would never pitch for the Rockies as they sent him to the Mariners for Steven Hensley just 5 days later. Harang has made 22 starts for Seattle this season, pitching to the tune of an atrocious 5.76 ERA and 64 ERA+. Fortunately for Harang, his FIP is significantly lower at 4.68, and his walk rate is the lowest it has been since his 2007 season with the Reds in which he finished 4th in NL Cy Young voting, giving him a good chance to be scooped up quickly were he to refuse assignment to the minors and opt for free agency.
Gutierrez's addition and Harang's subtraction gives the Mariners 6 outfielders and just 4 starting pitchers on their 25 man roster, so a subsequent transaction involving the call-up of a pitcher is likely. Outfielder Endy Chavez is the most probable candidate to be replaced on the roster.
