Pirates replace outfield grass after Stones concert

PITTSBURGH -- An approximately 10,000 square foot patch of
outfield grass was hastily replaced hours before the
Brewers-Pirates game at PNC Park on Friday night because of damage
caused by a Rolling Stones concert Wednesday.
Because the 7-story steel stage and its rigging were not fully
removed until Friday, the grass could not be replaced until the day
of the game. The swatch of repaired grass ran from the warning
track in right-center field to left-center and included most of the
ground normally covered by the center fielder.
Not only was the turf hastily replaced, the sod had to be
painted green. The painting wasn't finished until an hour before
the Pirates took pregame batting practice.
PNC Park is the third ballpark to require turf replacement
following a Rolling Stones concert this season, joining Comerica
Park in Detroit and Fenway Park in Boston. In those cities, larger
sections needed to be replaced: 22,500 square feet in Detroit and
40,000 square feet in Boston.
According to the Pirates, the PNC Park playing field is 96,000
square feet of Kentucky bluegrass.
