Drew Steckenrider, the Mariners’ saves leader last season, designated for assignment

Reliever Drew Steckenrider, who led the Mariners in saves last season with 14 saves, was named Saturday to make room for first/third baseman Kevin Padlo, who was waived off the San Giants. Francis.

The Mariners have seven days to trade Steckenrider or place him on irrevocable outright waivers. If he were to clear the waivers, the Mariners could retain him.

Steckenrider was one of the Mariners’ most pleasant surprises last season. He appeared in 62 games and had a 2.00 ERA and 1.02 WHIP in 67 2/3 innings.

But the 31-year-old Steckenrider has struggled this season, with a 5.65 ERA and 1.81 WHIP in 14 1/3 innings and was picked for the AAA Tacoma class on May 26. He allowed three runs and eight base runners in four innings with the Rainiers.

“Steck had a hell of a year last year, but is struggling to get things going in the right direction this year,” Mariners manager Scott Servais said. “I hope Steck stays in our organization, but who knows. He could be claimed.

“But I trust him because when he’s doing well he has a certain demeanor that he can throw in late games. He showed us what he could do there, but he has to go so far as to throw the ball where it needs to be thrown and move his secondary pitches forward.

Servais said Steckenrider was “probably the best of all in our bullpen to get the first hit.”

“But he hasn’t been doing that this year so far. That, in addition to (getting) quality secondary ground, whether it’s a substitution or a breaking ball, and finding something he can build on consistently. You can’t just take them out with a pitch (his fastball) and that’s kind of where it was at.

The Mariners claimed Padlo, 25, less than two months after trading him to the Giants for cash. It will relate to the AAA class Tacoma.

The Mariners claimed Padlo off waivers from Tampa Bay in August of last year. He appeared in one game – getting one at bat – with the Mariners last season.

Padlo started this season with Tacoma before being traded to the Giants on April 26. He played four games for San Francisco, at first and third base, and had two hits on 12 at bats.

“You look for ways to create depth if you have injuries or things like that, and I’m sure that’s where Padlo fits in,” Servais said.

Murphy progresses

Of the Mariners’ three injured offensive starters — receiver Tom Murphy (dislocated shoulder), outfielder Mitch Haniger (ankle) and outfielder/DH Kyle Lewis — Servais said Murphy is making the most progress.

“Tom Murphy is doing much better, but he’s not doing any real baseball activity yet,” Servais said. “He’s a few weeks away (from his return) and no specific date there.”

Lewis had concussion symptoms when he resumed physical activity and was slowed down because of it.

“Hopefully within a day or two we can get him back on the bike and get his heart rate up,” Servais said. “That’s kind of the first hurdle you have to overcome. When you increase your heart rate and sweat, how does that affect you? »

To note

Boston pitcher Garret Whitlock, who was scheduled to start Sunday’s game against Seattle, was on the injured list on Friday. Boston manager Alex Cora told reporters on Saturday he had a presentation plan for Sunday, but would not disclose it.
