Erasmo Ramirez appears headed up to join the Mariners after the club on Monday designated for assignment pitcher Jeremy Bonderman.

Mariners manager Eric Wedge said Bonderman’s scheduled start Thursday would be taken by a pitcher from Class AAA.

“We know who it’s going to be,” Wedge said. “Nothing I can release right now, but we’ll have to make that move, obviously, by Thursday.’’

Ramirez is about the only AAA option the Mariners have, because Taijuan Walker pitched for Tacoma on Sunday and would not be able to go on normal rest until Friday. James Paxton pitched Monday night, and Hector Noesi has been working long relief and hasn’t built the arm strength to start. Danny Hultzen has been hurt since the final week of June.

Wedge said the decision on Bonderman wasn’t so much about him getting rocked in his last two starts after a solid beginning to his comeback season.

“It’s really more about who’s coming,” Wedge said. “I think when you talk about Bondo, you’ve got to really appreciate his effort and what he’s done to get back to where he is. But we still feel there’s some more work to do there. Again, it’s more about who we’re bringing up than anything.’’

Ramirez, 23, looked like he’d make the Seattle rotation out of spring training before being sidelined by a triceps problem. He’s 3-3 with a 3.09 earned-run average in seven starts with 42 strikeouts and 14 walks for Tacoma.

Notes

• Left-handed relief pitcher Lucas Luetge got an advance tip some good fortune was headed his way when he ate lunch in Salt Lake City on Friday, and his fortune cookie contained the message: “Next Monday will be a lucky day for you.”

Sure enough, the Mariners recalled Luetge from Tacoma on Monday to take Bonderman’s roster spot. The team will make another move Thursday when a starter is added from AAA to the rotation.

“I’ve never had a fortune cookie be that specific,” Luetge said. “I didn’t tell anybody about it – not even my wife – until I found out for sure that I was coming back up.”

• Mariners leadoff hitter Brad Miller is quickly gaining a reputation as an “old school” player for shunning batting gloves. Miller admits he was tempted into to trying them for a few weeks at Clemson University, then decided to go barehanded again.

He doesn’t mind calluses and blisters on his hands.

“I like the feel of the bat,” he said. “My hands are disgusting … but I guess it’s natural for me.”
