Kade Anderson Promoted to MLB by Seattle Mariners

The Seattle Mariners have announced the promotion of their top prospect, left-handed pitcher Kade Anderson, from Double-A to the major leagues. Anderson is scheduled to make his MLB debut on Saturday against the Chicago Cubs.

This season in Double-A, Anderson has achieved a record of 10 wins and 1 loss, with an impressive earned run average of 1.06 over 18 starts. His promotion comes as the Mariners, currently with a record of 60-68, seek to improve their standing in the AL Wild Card race after a challenging series against the Milwaukee Brewers.

Anderson, who was selected third overall in the 2025 MLB Draft out of LSU, is expected to contribute to the Mariners' pitching strategy, potentially reinstating a six-man rotation. His development has been notable, as he joins other top prospects who have advanced directly to the majors without passing through Triple-A.
