I had heard this as well - and read it on the Padres website under "Mail Bag" :
What's the latest on moving in the fences at PETCO Park?
-- Doug M., Carlsbad, Calif.
With Major League Baseball's official approval, the club is chopping off the extreme corner in deepest right-center, changing the 411 mark to 400.
The major benefits probably will be psychological, giving left-handed hitters a sense that they have a legitimate shot at going deep in what has come to be known as Death Valley.
While the impact won't be profound -- this is still a pitcher's dream park -- it will reduce some of the physical strain on center fielder Mike Cameron and right fielder Brian Giles. And, over the long, hot summer, that can be meaningful, given the huge roles both veterans will play.
The club calculates that the new configuration would have added 12 homers to last year's PETCO count, which was third lowest in the Major Leagues at 118.
The alterations will be made in time for the semifinals and championship game of the inaugural World Baseball Classic, scheduled for March 18 and 20 at PETCO Park.
Management also is considering alterations to the right-field bleachers after the 2006 season, the idea being to improve sight lines by redesigning the seats.
