The Kansas City Royals announced plans to adjust the outfield dimensions at Kauffman Stadium, moving the fences inward by 8 to 10 feet to create a more balanced playing field. The changes, set for the 2026 season, aim to boost offense without turning the park into a hitter's haven. Wall heights will decrease, and new seating will be added in left and right fields.
The Kansas City Royals revealed on Tuesday that they are reshaping Kauffman Stadium's outfield for the 2026 season. The left- and right-field walls will shift inward by 9 to 10 feet near the foul poles, tapering toward center field, which remains at 410 feet from home plate. Specific adjustments include reducing the left-field corner from 356 feet to 347 feet and the right-field corner from 353 feet to 344 feet. The gaps in left-center and right-center will shorten from 389 feet to 379 feet, while wall heights drop from 10 feet to 8.5 feet in most areas.
This modification adds about 150 seats in left field and 80 new drink-rail seats in right field, bringing fans closer to the action. The Royals' research, led by vice president of research and development Dr. Daniel Mack and senior analyst Alan Kohler, considered factors like weather variance, altitude, and ball flight data. Kansas City, with the fourth-highest elevation among MLB parks, experiences significant temperature swings that affect play.
"Our goal here isn’t to have an offensive ballpark," general manager J.J. Picollo said. "It’s to have a very fair ballpark. We don’t want it to turn into a bandbox... We just want hitters to be rewarded when they hit the ball well, particularly in the gaps."
Historically, Kauffman Stadium—opened in 1973—has been homer-unfriendly, with Statcast park factors showing it in the bottom five for home runs over recent seasons. The Royals hit 70 home runs at home in 2025, compared to 89 on the road. Despite an overall league-average hitter-friendliness (101 factor), it excels in doubles (113) and triples (183). The team previously moved walls in by 10 feet from 1995 to 2003 before reverting.
The changes are projected to elevate the run value of fly balls from the bottom third to the middle of MLB parks, benefiting young power hitters like Jac Caglianone and Vinnie Pasquantino, as well as Salvador Perez, without overly harming the pitching staff. Pitchers allowed just 0.99 home runs per nine innings at home in 2025, eighth-best in the league.
"Making this a fairer ballpark will help with roster construction," Mack said, noting the adjustments account for the next five years before a planned new stadium post-2030. Work has begun and will finish before the March 30, 2026, home opener against the Twins. The Royals, who finished 82-80 in 2025 after a wild-card appearance in 2024, seek consistency across venues.
