The Arizona Diamondbacks spent about $3.3 million upgrading Chase Field in the year since the team took control of the stadium from Maricopa County government, records show.
The bulk of the money — nearly $2.7 million — went to converting the field from grass to artificial turf earlier this year. Freight elevators, audio equipment and lighting equipment also were repaired or purchased.
The team has struggled during summers to maintain grass at Chase Field because the retractable roof needed to be open to give the grass sunlight but closed before games to cool down the stadium for fans.
