Kade Anderson, the third overall pick in the 2025 draft and, per one prospect ranker, the top prospect in baseball, made his major league debut for the Seattle Mariners against the Chicago Cubs. After a dominant Double-A season — 10-1, a 1.06 ERA, 135 strikeouts against 13 walks — he skipped the lower minors entirely, and his call-up made him the first player from his draft class to reach the majors.
Anderson retired nine of his first ten batters before the Cubs caught up to him in the sixth, when Pete Crow-Armstrong doubled and Alex Bregman and Michael Busch followed with back-to-back home runs. He left trailing 3-2, but Seattle rallied for three runs in the ninth, capped by a walk-off homer from Randy Arozarena, who had earlier robbed a Cubs batter of one himself.
The promotion also puts Anderson on the 40-man roster, meaning the Mariners cannot contact him during a potential lockout beginning December 1st — an odd wrinkle for a franchise hoping to shore up a pitching staff that has posted the third-worst ERA in baseball since late July.
