SEATTLE – Seattle Mariners outfielder/first baseman Luke Raley began his rehab assignment with Triple-A Tacoma on Thursday night.

M’s Injury Updates: The latest on Logan Gilbert and Bryce Miller

Raley went 0 for 4 with a strikeout in what was his first game action since suffering a Grade 1 right oblique strain during batting practice on April 29.

Mariners general manager Justin Hollander said Raley will get an off day Friday before resuming his rehab assignment with Tacoma on Saturday and Sunday.

Hollander said Raley would then likely need some more games with Tacoma next week before the Mariners decide whether to active him from the injured list. Tacoma has an off day Monday before starting a six-game series at home on Tuesday.

Hollander said the biggest factor for Raley right now is readjusting to the timing of live pitching.

“He felt great after yesterday,” Hollander said. “… I talked to him earlier and he said everything felt great. But there is some timing that’s required if you’re going in swinging at live pitching for the first time in over a month now.”

Here are some other injury updates Hollander provided on Friday afternoon ahead of the Mariners’ series opener against the Cleveland Guardians.

• Outfielder Victor Robles remains on track to resume baseball activities in July and return to the Mariners in September, if all goes well.

Robles has been sidelined since dislocating his left shoulder and fracturing a bone in his shoulder while making a spectacular catch on April 6.

“When you’re immobilized for that long and you have that kind of traumatic injury to your shoulder, range of motion obviously decreases a lot, and we need to build that back and do it in a measured, responsible way,” Hollander said.

“If we push too hard, too fast, obviously there could be a reinjury. We don’t want to have that, so September is what we’re looking at.”

• Right-handed reliever Gregory Santos, who underwent a cleanup knee surgery on April 29, is in a throwing progression. Hollander said he’s still on track for a potential return in July, but noted “that’s a very rough, date of return.”

• Right-handed reliever Collin Snider, who was placed on the IL with a flexor strain in his pitching forearm on June 4, has resumed throwing again. Hollander said he’ll likely need another two to three weeks to ramp up again before returning.

• Left-handed reliever Tayler Saucedo, who is on the injured list at Triple-A Tacoma with a strained left lat, is “doing extremely well” in his throwing progression, Hollander said. The Mariners are targeting early July return for him.

“He said he feels great right now – better than he did in the spring in a lot of ways,” Hollander said.
