The Mariners want to get the 22-year-old Nicaraguan more time in the Minors after he went 1-0 with a 5.11 ERA in three starts during his rehab stint.
"He's got to earn his way back up here, it's as simple as that," manager Eric Wedge said Monday. "Our starting pitching up here has been pretty good. He's a young pitcher. His last outing was better, his outing before wasn't very good. So he just has to be more consistent and earn his way back up here, no different than [Hector] Noesi or anybody else down there."
Ramirez was pulled from his last start with the Mariners on June 30 after feeling discomfort in his right elbow. He had split time between Seattle and Tacoma already this season, going 0-2 with a 3.82 ERA in 11 appearances -- including four starts -- with the Mariners and 4-2 with a 3.60 ERA in 10 starts with the Rainiers.
Since Ramirez went on the disabled list, Blake Beavan has solidified his spot in the rotation with four straight wins since being recalled from Tacoma.
"He's taken advantage of it," Wedge said. "He's been pitching well, so hopefully he'll continue doing that."
Hisashi Iwakuma has also pitched well since moving into the rotation just prior to the All-Star break.
