The Mariners announced today that the fences will come in for the 2013 baseball season.

From the left field corner to a point about midway between the bullpens, the wall will be moved in four-feet. The biggest change will be from the left field power alley area to straightaway center, where the wall will be as much as 17-feet closer to home plate. From straightaway center to right center, the wall will be moved in-four feet.

Another noticeable change will be in the left field corner. The hand-operated scoreboard will no longer be in play, and will be relocated to a new location above left field as part of seating modifications that will be announced at a later date. Currently in the left field corner, the wall is 16-feet high with the hand-operated scoreboard in play. After the board is moved, the outfield wall will be eight-feet high there, making it the same height from foul pole to foul pole.

Glad to see them make this change. I'd love to see a spray chart that overlays the new fences with the current one to see how this may effect balls in play.
