BA Grade: 60/High
Following a 2024 freshman season in which he carved out a meaningful role, Anderson enjoyed a career year in 2025 when he was a first team all-SEC selection after posting a 3.18 ERA with 180 strikeouts to just 35 walks across 119 innings. Anderson has a slender frame at 6-foot-2, 185 pounds with some present strength in his lower half. He has a simple delivery in which he starts with his shoulders almost square to the first base dugout. Anderson begins his motion with an extremely small sidestep that leads into a high leg lift. He has a short and compact arm action and attacks from a high three-quarters slot with above-average arm speed. Anderson’s fastball sits in the 92-95 range, but has been up to 97 with plus carry in the top of the zone. The biggest revelation in Anderson’s arsenal in 2025 was his mid-80s slider—a pitch he threw just 2% of the time in 2024. It emerged as an above-average offering that flashes plus with lateral life, and garnered a 30% miss rate. Anderson’s upper-70s high-spin curveball is a plus pitch that has great pure spin rates, excellent depth and distinct shape from his slider. Anderson rounds out his arsenal with a mid-80s changeup that also took a step forward in his draft-eligible sophomore season. It’s an average fourth pitch that flashes tumbling life, and it’s especially effective against righthanded hitters. Anderson is a plus strike-thrower who has an above-average feel for his entire four-pitch mix. Perhaps the only blemish on Anderson’s resume is the fact that he’s already had Tommy John surgery. He’s a high-probability starter with physical projection, a blend of strikes and stuff that gives him midrotation upside and has a chance to be the first college pitcher off the board.

Track Record: LSU has a track record for developing future big leaguers, and Anderson is on that trajectory. A Louisiana native, Anderson’s high school career was cut short by Tommy John surgery that cost him his senior year. After splitting time between LSU’s bullpen and rotation as a freshman in 2024, he broke out in 2025. His 180 strikeouts led all Division I pitchers and were the third-most in program history en route to being named the Most Outstanding Player in the College World Series after the Tigers’ run to a national title. The Mariners drafted him third overall and signed him for an underslot $8.8 million. He did not make his pro debut.
Scouting Report: A 6-foot-2 lefty with a strong lower half, Anderson has a smooth delivery and a compact arm action from a high three-quarters slot. In 2025, his mid-80s slider became a key weapon. It regularly flashed plus and generated a 30% whiff rate. He also features a high-spin, upper-70s curveball with depth and a mid-80s changeup that’s effective against righties and looked better in 2025. An above-average strike-thrower with feel for all four pitches, Anderson’s previous elbow surgery and slighter build are concerns, though he held up over 119 innings in his draft year, and evaluators believe there’s some projection remaining. While he didn’t make his pro debut, the Mariners focused on developing his strength during his time at the complex.
The Future: Anderson is a high-probability starter with a blend of strikes and stuff that gives him No. 2 or 3 starter upside. He has the polish and pedigree to move quickly, perhaps even reaching Seattle by the end of 2026, though the Mariners won’t need to rush him considering they have one of baseball’s best rotations.
