The Mariners designated Bolton for assignment Saturday.

EDGE Analysis

Bolton turned in a 4.34 ERA and 1.45 WHIP across 18.2 innings with the Mariners last season, and he's allowed two runs over two innings in Triple-A to begin the 2025 campaign. He'll now end up as the odd man out on the 40-man roster to make room for Jesse Hahn, who was selected to the active roster Saturday.
