As fans fill Anaheim’s Angel Stadium today for the team’s home opener, it isn’t just an upgraded infield roster that awaits them. The stadium has made a host of upgrades to help fans see and hear the game.

Bigger, brighter LED screens from South Dakota-based Daktronics will make it easier to see lineups, replays and videos, and a state-of-the-art sound system will broadcast each play and rouse fans, team spokesman Tim Mead said.

“All this is about the fan experience here,” Mead said of the slew of additions made in the offseason to what is the fourth-oldest stadium in Major League Baseball.

He declined to share the cost of the improvements, which took about four months to install.

Right field: The new 9,500-square-foot screen with 7.7 million LEDs was so bright at a March 25 game, one fan wrote on Facebook he had to wear sunglasses. It’s the third-largest screen in a Major League Baseball stadium.
