2026 Fantasy Outlook
The hierarchy of college starters typically evolves throughout the spring, and in 2025 it was Anderson who rushed up draft boards as he struck out double-digit batters in seven of his nine starts for LSU in April and May. He landed in a dream spot on draft day, with the Mariners selecting him third overall and giving him the second largest bonus ($8.8 million) in the draft. Anderson had Tommy John surgery in April 2022 and returned to action as a midweek starter and weekend reliever as a freshman before breaking out last year while leading the nation in strikeouts as a draft-eligible sophomore. The 6-foot-2, 180-pound lefty touches 96 mph with his low-90s fastball that has great movement, and it's his full arsenal of above-average-to-plus offerings that overwhelms hitters. His curveball, slider and changeup, all which will flash plus, move in different directions while coming out of the same arm slot. Anderson had a 3.60 ERA, 1.07 WHIP and 170:30 K:BB through 110 innings in 2025. It was a big jump from the 38.1 innings he logged in 2024, and he understandably didn't pitch after signing. Anderson may need just a dozen starts in the minors before he looks like an option for the big-league rotation. Read Past Outlooks
Gets aggressive assignment
Anderson is opening the season with Double-A Arkansas, Daniel Kramer of MLB.com reports.
Analysis
Most of the top college arms get assigned to High-A for their first full season, so while this assignment may not be a big surprise, it is notable. Per the report, the initial plan was to assign Anderson to High-A Everett, but the calculus changed after Anderson made such a strong impression this spring. The less volatile weather conditions in Arkansas compared to the Pacific Northwest in April also factored into the decision. What makes the assignment even more notable is that the Mariners have a track record of jumping their best pitching prospects from Double-A to the majors, bypassing the Pacific Coast League. Ryan Sloan, the Mariners other premium pitching prospect, is also opening the year at Double-A.
