The Mariners play at Safeco Field in Seattle. It’s a nice stadium with a well-earned reputation for being a very unfriendly ballpark for hitters. In fact, ESPN’s park factors lists it as the most offensively depressing in the league, while StatCorner suggests that of the 100 home runs that get hit at an average baseball park by right-handed hitters, only 68 would still be home runs at Safeco Field.

So, the organization is attempting to change all that by bringing in the walls at the park, by as much as 17 feet in some areas. The biggest changes will be in the left field power alley, which should in turn make things easier on the previously hindered right-handed hitters.

The changes:

  • The distance from home plate to the left field foul poll will remain at 331 feet.
  • The distance from home plate to the left-center power alley will go from 390 ft. to 378 ft.
  • The distance from home plate to the deepest point of the park will go from 409 ft. to 405 ft.
  • The distance from home plate to dead center field will go from 405 ft. to 401 ft.
  • The distance from home plate to the right-center power alley will go from 385 ft. to 381 ft.
  • The distance from home plate to the right field foul poll will remain at 326 ft.
  • The manual scoreboard will be moved out of play, above the fence.
  • The outfield wall will be eight feet high, all the way around the outfield.

So, it’s probably fairly safe to assume all these adjustments are merely a means of making management look a bit better following the acquisition of the right-handed hitting Jesus Montero who had a disastrous rookie year in Seattle. Or, maybe they’re doing it because the plan worked out so well for the New York Mets.
