• Erasmo Ramirez was transferred from Class A Advanced High Desert to Tacoma on Monday and is in line to make his second Minor League start on Friday for the Rainiers against Las Vegas at Cheney Stadium. Ramirez threw six innings for High Desert on Sunday, allowing six runs (five earned) with eight hits, two walks and seven strikeouts against Scottsdale.
Ramirez is pitching in the Minors to stay on schedule, as the Mariners have gone temporarily to a four-man rotation with several off-days to work around in the past few days. Ramirez is on schedule to return if needed on May 7, when Seattle has a doubleheader in Oakland.
• Veteran right-handed reliever Ramon Ramirez was released from Tacoma to make room on the Rainiers' roster after posting a 10.38 ERA in four appearances over 4 1/3 innings in Tacoma. Ramirez was not on the 40-man roster after signing a Minor League deal over the offseason.
• Outfielder/designated hitter Logan Morrison is eligible to come off the 15-day disabled list on Wednesday, but McClendon said Morrison's strained right hamstring is not yet strong enough for him to start a Minor League rehab assignment.
Morrison remained in Seattle to work with team trainers, as did injured pitchers Taijuan Walker and James Paxton, who have both begun playing catch over the last few days.
