SEATTLE -- On a crowded 40-man roster full of Matts -- Wisler, Festa and Carasiti -- the Mariners are simply going to call the newest namesake by his nickname: Goose.

That would be Matt Magill, who arrived at T-Mobile Park on Monday, one day after he was acquired from the Twins for cash considerations. Magill took the roster spot of Matt Festa, who was optioned to Triple-A Tacoma. “Goose” is a token to the film Top Gun, and Magill also has an 11-month-old son named Maverick.

“That’s the only name we agreed on,” Magill said. “So, then the Goose thing kind of took off with the old team. They were like, 'You're going to be his wing man.'”

Magill, who had a 4.45 ERA over 28 1/3 innings with the Twins, is the latest addition to a Seattle bullpen that has used 31 relievers this season, by far an MLB high. The turnover reflects an approach of unknown opportunity. As the last-place Mariners maneuver their way through what they’ve publicly called a “step-back” season, the club has been acquiring buy-low talent externally, with the hopes that it could blossom into a potentially long-term fixture.

Right-hander Austin Adams, who was acquired from Washington and became Seattle’s best reliever before injuring his pitching shoulder on July 4, is the most notable example.

“It's opportunity. We've preached it all year long,” Mariners manager Scott Servais said. “Certainly, in our bullpen, we knew that was going to be the issue. It's probably gotten bigger than we thought, or more opportunity than we anticipated, just because of the injuries that we've had, so now you've got a chance to bring more guys in.”

Magill likely won’t pitch in high-leverage situations right away, Servais said, but he could work his way there if he pitches well. Seattle’s analytics staff liked what it saw from Magill, particularly his tight-spinning curveball that complements a four-seam fastball that averages 95.3 mph. Magill is throwing his curveball for 25.3 percent of his total usage this season, up from 16.1 percent last year, and he’s using it early in counts -- 75 percent of them by the second pitch.

“The curveball might be his outlier pitch that we can maybe utilize a little bit more and see how it plays,” Servais said. “He has tried to turn to it more because it's a good pitch.”

Magill’s stuff has the behavior that lends to missing bats, but when hitters are making contact, they’re doing so at a high and hard level. Magill’s 90.5-mph average exit velocity allowed and his 43.8 percent hard-hit rate (anything 95 mph or higher) rank among the bottom seven percent in the Majors.

Magill experienced shoulder fatigue early in the season with Minnesota, and outside of a few poor outings (four earned runs twice and two runs another two times), he said he’s pitched confidently. Twenty-two of his 28 outings were scoreless, though 96 of his 133 plate appearances were low-leverage for the pennant-chasing Twins, according to Baseball-Reference.

“The usage of me, the team was winning, I didn't pitch so often, so it was a different kind of usage,” Magill said. “I don't like making excuses at all. Every time we go out on the field, our goal is to get outs, and it's a hard sport. Everyone is going to get beat up sometimes, but I feel like if you took away three outings from my year, it'd be a completely different year. ... I’m happy that’s what the Mariners thought.”
