At the major league level, the Seattle Mariners are a frustrating 17-20 entering play on Wednesday afternoon.

But at the minor league level, the Mariners have a lot of good things brewing, including the development of top pitching prospect Kade Anderson.

The lefty, selected No. 3 overall out of LSU in 2025, has dominated at Double-A Arkansas.

In his first taste of professional action, Anderson is 2-0 in five starts with a microscopic 0.37 ERA. He's got 38 strikeouts in 24.1 innings, looking every bit the part of a first-round pick and a potential rotation cornerstone. 

And everyone is taking notice, including the people at Baseball America, who gave Anderson some major attention in the latest edition of their Top 100 prospects.

He began the year as the No. 25 prospect in their system (in January), but he's all the way up to No. 9, making him the No. 3 pitching prospect in the sport, behind only Trey Yesavage (Blue Jays) and Payton Tolle (Red Sox).

Yesavage and Tolle will both soon graduate off the list, leaving Anderson as the top pitching prospect.

The general thought on the lefty is that he doesn't have top-end, ace stuff, but that he has an understanding of pitching and who he is as a pitcher. He won't wow you with velocity, but he'll still sit in the mid-90s with a good array of offspeed pitches.

He may not have as high a ceiling as Ryan Sloan, but he's likely ready to help the major league roster as early as this season, and if the Mariners injury situation continues to worsen, then he could be up sooner rather than later.

He features a solid amount of polish and comes with big game experience, having helped LSU win the College World Series in 2025.

--Top prospect Colt Emerson is up to the No. 4 ranked prospect in the sport, meaning that the Mariners join the Pittsburgh Pirates as the only teams with two players inside the top ten.

--Sloan now sits at the No. 20 prospect spot. He was No. 60 in the January rankings.

--Michael Arroyo, Lazaro Montes, Jonny Farmelo and Felnin Celesten have all been well-regarded prospects before, but none are in the Top 100 at Baseball America right now. We recently wrote about Celesten based on an interview we did with Everett AquaSox broadcaster Pat Dillon on the most recent episode of the 'Refuse to Lose' podcast.

Montes was No. 58 in January.
