The Arizona Diamondbacks extended the netting at Chase Field last season to better protect fans.

The club hasn't discussed the change as other teams await an edict from Major League Baseball to do so. A fan was seriously injured at Fenway Park earlier this month.

At the start of the 2014 season, the Diamondbacks extended their netting, which is 30 feet high, from 73 to 150 feet in length.
