The team is giving away field box tickets for the 5:05 p.m. game, courtesy of SaveMart.
After winning the first two games of the series in El Paso, the Grizzlies lost the next two games at home, including a 4-2 loss on Saturday in front of 5,116 fans at Chukchansi Park.
They want a bigger crowd for Sunday's game and the price is right, so you can pick up tickets at the H St. ticket office before the game.
They're also giving away F-Slash caps and Growlifornia flags at the gates while supplies last.
