Of the eight prospects the Mariners sent to the Arizona Fall League this year, catching prospect Boston Smith was the biggest name sent by Seattle and has occupied the lion’s share of the headlines. But you should know about a different Smith, as well: Adam Smith, the 26-year-old reliever who makes up the other half of the Mariners’ AFL “Mr. and Mr. Smith” battery.
Acquired when the Mariners purchased his contract from the independent Lancaster Stormers last May to fill out Everett’s bullpen, Smith
quickly overpowered the youngsters at High-A and earned a trip to Double-A Arkansas midway through the season, where his strikeouts fell and his walks shot up. Smith has a prototypical pitcher’s frame at a strongly-built 6’2”, but relies more on spin and location than velocity to outfox hitters. On the stat sheet, nothing about Smith stands out: he didn’t rack up eye-watering strikeout numbers in Arkansas, and he’s carrying an ERA north of 5 in the Fall League.
But on a trip to the AFL last month, I watched Smith pitch the most dominant inning of the night in a lopsided Peoria win. Hitters simply weren’t reading the ball out of his hand, swinging ugly or backing away from pitches that landed squarely in the zone.
So far, Smith has appeared in seven games in the AFL, pitching 6.2 innings, over which time he is yet to issue a walk while striking out 10, leading to his selection to the Fall Stars game.
Smith was initially drafted by the Padres in the 14th round in 2021 out of UNC Wilmington, where he spent four years before spending one year in the Red Sox system. He then transitioned to indy ball, which is where the Mariners found him.
As a former starter, Smith has a full arsenal at his disposal as a reliever: a four-seam, sinker, cutter, changeup, and sweeper. He mixes his pitches effectively, keeping hitters off-balance, but says he relies more heavily on his off-speed, since he’s not blessed with eye-popping velocity on his fastball. Of his off-speed pitches, he has a clear favorite.
“I would say I get most of the ugly swings from my sweeper,” said Smith. “It’s kind of my go-to, the old reliable. I learned it about two years ago, and then once I really figured out how to use it, I haven’t gone away from it.”
Smith says in his time with the Mariners he’s learned to not be afraid of throwing in the zone, buying into the “dominate the zone” philosophy and trusting in what the organization has told him about what makes him good. Ironically, that confidence to throw in the zone despite not having huge velocity and lean in to his identity as a pitcher who pounds the zone has caused his velocity to tick up into the mid-90s.
“The velocity aspect early in my career wasn’t really there, and being a part of two different organizations prior where they strive for only velocity just didn’t fit my motto because I was more of an in-zone pitcher, get a lot of strikes, and just average velocity. Whereas here, being able to embrace the identity of being in the zone all the time has translated into my velocity being where it’s at now.”
But it’s not just the uptick in strikeouts or velocity that Smith is grateful for. He’s happy to be with the Mariners because he feels like the organization has a clear direction for how to make him successful, a vision that’s communicated clearly and consistently.
“Everyone’s got a plan here, and they’re solely driven on that plan, and everyone’s bought into the plan, which is that communication aspect where everyone is in tune with what’s going on,” Smith said. “I think it makes it a lot easier for us as players when we’re communicated with on a daily basis about what we need to do, maybe in our routine or changing other things up. Everything is communicated. It’s not like we have to find out a few months later, like, oh, we’ve been actually wanting you to do this, but we didn’t tell you. It’s very upfront.”
Those are encouraging words to hear from any player in your organization, but especially considering the apparent communication breakdown that hurt the big-league club this year. It’s a reminder of what this organization does well when those avenues of communication are free-flowing and meaningful, a big part of which is identifying players like Adam Smith and helping them become the best version of themselves.
You can watch Smith pitch in the Fall Stars game on Sunday at 5 PM PT; the game will be broadcast on MLB Network, but you can also stream it on MLB.com.
