Mariners Call Up Kade Anderson Because Their Rotation Wasn't Terrifying Enough

The Seattle Mariners are calling up left-hander Kade Anderson to start on Saturday, and if you haven't been tracking Double-A Arkansas, you are about to see a video game create-a-player in real life.

ESPN's Jeff Passan broke the news that the top pitching prospect in baseball is officially making the jump. Anderson was the third overall pick in the 2025 draft out of LSU, and he has spent his entire minor league stint treating professional hitters like they are holding pool noodles.

"ESPN's Jeff Passan reported the call-up, noting Anderson is the top pitching prospect in baseball."

The 22-year-old is sitting on a 1.06 ERA over 93.1 innings. He has struck out 135 batters while walking exactly 13.

For context, striking out ten guys for every one you walk is not a real baseball stat. That is what happens when you play MLB The Show on rookie mode and refuse to adjust the sliders. He also boasts a comical 0.64 WHIP, meaning opposing teams are basically flipping a coin just to get a guy on first base.

He makes his major league debut Saturday against the Chicago Cubs in Seattle. Anyone looking at the strikeout prop markets is going to have a fascinating weekend, because Anderson has been carving up lineups with a four-pitch mix anchored by a fastball and a changeup that makes right-handed hitters look completely lost.

The funniest part of this entire move is that Seattle does not even desperately need him. The Mariners already have one of the deepest rotations in the sport and boast a team ERA hovering around 2.86. Adding the best pitching prospect on earth to a staff that already suffocates opponents is just objectively greedy.

Saturday night in Seattle is now mandatory viewing. If Anderson translates even a fraction of his minor league dominance to the big leagues, the rest of the American League is going to have a miserable time trying to score runs this fall.
