Matt Brash spent his Monday afternoon walking around T-Mobile Park, meeting players that would now be his teammates, throwing a little off the bullpen mound and trying to adjust to a whirlwind three days.

On Tuesday, in what will be his first official day in the big leagues, the talented pitching prospect is expected to make his MLB debut with the Mariners. He enters final week of the MLB season with his team trying to win all five remaining games on its schedule in hopes of ending the longest active postseason drought in professional sports.

The Mariners selected Brash’s minor-league contract and added him to the active roster. To make room for him, right-hander Matt Andriese was designated for assignment.

“It’s a pretty cool moment,” he said pregame. “I’m still taking it all in, but I’m just excited to be here and I’m gonna help the team out in any way I can. I’ve got some family coming in and some childhood friends coming so I’m pretty excited to hopefully play in front of them.”

Following another dismal outing from Yusei Kikuchi on Thursday, the Mariners began discussing possible options for a replacement for his next start. When the team announced it had promoted Brash from Class AA Arkansas to Class AAA Tacoma on Friday, it became clear that they were making an alternative plan instead of starting Kikuchi.

The expectation was that Seattle would give Brash that start, particularly when he was seen on the field on Tuesday. But when Tyler Anderson made it just two innings in a brutal start vs. the Angels on Saturday, throwing just 54 pitches, the Mariners were presented with a different alternative plan.


“Tyler’s last time out was shorter and he got roughed up a little bit,” manager Scott Servais said after Tuesday’s 13-4 win. “Tomorrow would be his typical bullpen day so he’ll start the game. Of course, he will not go 100 pitches. We will be very cautious with him. But that’s where we’ll head tomorrow and then we’ll piece it together after that.”

Brash is available to pitch multiple innings of relief, which the Mariners felt might be an easier debut instead of starting him against a veteran A’s lineup with so much on the line.

Admittedly, Brash wasn’t on Servais radar during spring training. But he read the reports and saw some video throughout the season.

“Did I think he would be here at this point,” Servais said. “I have to be honest. No, I didn’t. But there were a lot of firsts for us this year. And the fact that we’re in this position at this point in the season, you want to give our team every opportunity, put the best talent out there that gives us the chance. He’s got talent. He’s handled everything that’s been thrown at him so far.”

Using a fastball that can touch 100 mph and a nasty wipeout slider, Brash has dominated opposing hitters at the High-A and Double-A level.

He was recently added into Baseball America’s Top 100 prospects at No. 99. He appeared in 10 games for High-A Everett, posting a 3-2 record with a save and a 2.55 earned-run average.


He was promoted to Arkansas in mid-July. In 10 starts with the Travelers, he had a 3-2 record with a 2.13 ERA with 80 strikeouts and 23 walks in 55 innings. Opponents had a .162/.249/.237 slash line against him.

Kikuchi was informed about the decision after batting practice.

“I really appreciate how Yusei he handled things,” Servais said. “He was very professional. He understands where the team is at, understands that he has not performed recently like he did in the first half. He still wants to contribute any way he can. He’ll be in the bullpen. If we need to use him out of the bullpen, we will. He was an absolute pro. I can’t say enough about how he handled it. He wasn’t particularly happy, but who would be?”

In his past 14 starts, Kikuchi has posted a 1-6 record with a 6.22 ERA. In 63 2/3 innings, he’s allowed a whopping 80 hits, including 12 homers with 70 strikeouts and 31 walks. Opponents had a .304/.385/.532 slash line against him over that time. Three of his past four outings have lasted three innings or fewer.

Dave Henderson Minor League Staff Member of the Year Award: Louis Boyd, manager Everett AquaSox

In his third season in the Mariners organization and his first full season as the manager for the Mariners High-A affiliate, Boyd handled some of the organization’s top prospect with the AquaSox.
