Overview
- New dimensions pull the corners to 347 feet in left and 344 feet in right, move the alleys from 389 to 379 feet, and keep center field at 410 feet.
- Wall height drops from 10 feet to 8½ feet in most areas, with about 150 seats added in left field and roughly 80 drink‑rail spots added in right.
- Work on the new configuration has begun and is scheduled to be finished before the March 30 home opener against the Twins.
- The club says the changes should lift the run value of fly balls toward league average and projects roughly 1.5 additional home wins per year.
- Kansas City frames the shift as a five‑year evaluation before a new ballpark, noting prior fence moves in 1995–2003 and expecting their power bats, including Bobby Witt Jr. and Vinnie Pasquantino, to benefit.
