Thanks to Kevin Tulley for the research help (see message below) on the
issue of the marked vs. actual dimensions at Citizens Bank Park. I checked
out the park diagram on the Phillies' website. This seating diagram shows
both the LF and RF fences to be at 90 degrees to the foul lines. Therefore
by not very complicated high-school geometry the following dimensions must
be true:

LF foul line 329
Straightaway LF (15 degrees) 341
LF Power Alley (22.5 degrees) 356
LC (30 degrees) 380

RF foul line 330
Straightaway RF (15 degrees) 342
RF Power Alley (22.5 degrees) 357
RC (30 degrees) 381

Note that the CF dimensions cannot be verified using only geometry, because
of the LC notch and CF diagonal fence. However the CF dimensions from the
Phillies' website seating diagram are consistent with the LF and RF fences
being at 90 degrees to the foul lines.

Also note that in an earlier message on this same subject I was in error in
stating that the LF and RF dimensions were both 330.

The Phillies stated objective about the dimensions at Citizens Bank Park
having intended to be about the same as at Veterans Stadium were not
achieved for LF or RF. Herein follows a comparison of average OF distances
by field for the two parks:

Citizens Bank Veterans
LF 346 357
CF 396 396
RF 347 357

Park Composite 363 370

HR Park Factors for Veterans Stadium were 2001-03 = 93.3 (three year
average) while for Citizens Bank Park 2005 = 128.9

This comparison suggests that Citizens Bank Park has become a noticeably
better HR hitters parks due to relatively small decreases in the LF and RF
dimensions.

Ron,
I've been to many games there and it looks to me that they are at a 90
degree angle. And looking at a seating diagram from before the 2004 season
and the 2005 season, it looks like they are at a 90 degree angle.
Saturday's Philadelphia Inquirer said, "Players and coaches contend the
power alley in left field sits between 345 and 358.5, which would make it
the shortest in the National League." Saturday's Allentown Morning Call
said, "The two-year old facility has been ridiculed by all pitchers, who
insist the power alleys - especially left field, which was erroneously
listed at 369 feet for some time - made it a "joke" and a "travesty"."
