MLB Stadium Shifts Set to Shake Up Fantasy Baseball in 2025

The Baltimore Orioles are tweaking Oriole Park once again, this time pulling their left-field wall closer after pushing it back too far before the 2022 season. Aiming for a “happier medium,” the new dimensions won’t revert to the park’s original shallow setup but should still juice up the offense. Over the past three years, the deeper wall stifled 196 home runs, slashing right-handed batters’ homer output by 21%—the third-highest suppression in MLB—and posting the second-lowest HR/FB rate for righties since 2023. Fantasy managers should expect a noticeable uptick in power numbers from Orioles hitters, making them sneaky targets in drafts.

Meanwhile, the Tampa Bay Rays are swapping hurricane-ravaged Tropicana Field for the Yankees’ spring training home, Steinbrenner Field, which mirrors Yankee Stadium’s hitter-friendly dimensions. Tropicana has been a pitcher’s paradise, ranking as MLB’s second-best run-suppressor over the last three seasons and particularly tough on lefty homers. Yankee Stadium, by contrast, has boosted long balls by 19%, and Tampa’s hitters—long vocal about Tropicana’s poor batter’s eye—may see sharper vision in their new digs. The Rays’ offense could surge in this warm-weather pseudo-Yankee Stadium, warranting a fantasy boost for hitters and a downgrade for pitchers. Across the league, the A’s are also on the move, leaving Oakland’s run-stifling Coliseum (down 6% in scoring, 19% in homers) for Sacramento’s Sutter Health Park. With a neutral park factor, smaller foul territory, and a fresh batter’s eye, A’s bats could awaken from their slumber, offering fantasy upside in 2025.
