Faded top prospect just took Mariners comeback story to new level with remarkable HR

When the Seattle Mariners signed Brennen Davis in January, there weren't expectations so much as nostalgia. Considering that he still hasn't played in the majors since his days as a top prospect, that's not a good thing.

Goodness, how times have changed. Davis has dramatically shifted the conversation with his play in the Cactus League, specifically from over the player he could have been back to the player he might still be. And he's done it with one loud swing at a time.

The 26-year-old has put 17 balls in play this spring and averaged (yes, averaged) 98.3 mph on those, with highs of 114.1, 115.8 and 116.7 mph on three of his four home runs. The 115.8 mph one was on Sunday, and it landed a projected 464 feet from home plate.

This is frankly getting ridiculous, to a point where a whole new question has to be asked. Never mind where he fits in the organization. How might the Mariners fit Davis into their big league roster in 2026?

Brennen Davis' spring training power show is forcing questions about Mariners' plans for him

For now, at least, Davis is still not a realistic candidate to break camp with the Mariners as part of their Opening Day roster.

He isn't part of the 40-man roster, for one. And for two, he can only play left field, right field and designated hitter. Between Randy Arozarena, Luke Raley, Victor Robles, Dominic Canzone and Rob Refsnyder, the Mariners are well equipped with depth and talent in those spots.

It's also worth bearing in mind why Davis still hasn't appeared in the majors. He was drafted all the way back in 2018, and he peaked as MLB Pipeline's No. 15 overall prospect in 2022. But injuries have been a constant theme, and especially over the last four seasons. With guys like that, you have to be careful to not throw caution to the wind.

All that said, nobody has forgotten that right field was a black hole for the Mariners in 2025. By running it back with the same guys who were responsible for that, they're hoping for redemption but risking further headaches.

This is where Davis might come into play at some point this season. And if nothing else, what he's done this spring is successfully position himself as the next man up. Even if Lazaro Montes or Jonny Farmelo is the future in right field, neither is a lock to debut this year. Montes is certainly the closer of the two, yet even he has yet to make it to the Triple-A level.

So, definitely keep an eye on Davis over the next few weeks. And an ear as well, because that bat sure is making some sweet sounds.
