Neither team shot well from the line. The Vikings connected on seven of 20 attempts for 35 percent and the Bulldogs hit only six of 13 attempts, or 46 percent.
Lopez hit a shot to tie the game at 6-6 with 37 seconds remaining in the first quarter, but that was plenty of time for the Bulldogs to begin a run as Carboni followed a rebound with a score with 10 seconds left. Time expired with the Bulldogs holding an 8-6 lead.
Holtville's Claudia Lopez could have tied the game early in the second quarter as she went to the line but missed both free throws, only to have Calexico's Carla Esquer hit on the other end as she was fouled. Esquer hit her free throw and Calexico continued an 8-0 run that ate up 5:30 of game time.
Johnston ended the Holtville drought with a basket with 3:07 left in the half and Rothfleisch pulled the Vikings closer with two quick baskets on inbound passes. Not 10 seconds later, Lizeth Lopez hit Carboni, who scored with 27 seconds remaining.
Claudia Lopez made one of two free throws to pull the Vikings as close as they would get at 20-15 with seven seconds to go, but Carillo nailed a basket as time expired to send the teams to the locker room with Calexico ahead 22-15.
Calexico took only about 15 seconds in the second half before getting a basket from Carboni.
Claudia Lopez connected again for the Vikings, but the Bulldogs began another run that included an impressive coast-to-coast fast break by Bianca Sanchez. The 9-0 run lasted until the 1:22 mark when Johnston again ended the drought with a jumper.
The teams traded baskets and the third quarter ended with Calexico up 37-20.
Holtville went on a couple of spurts in the fourth quarter to pull within 37-25 and 41-29, but could still not connect consistently on free throws, allowing the Bulldogs to again take full control of the game.
Erica Baez hit a shot for the Vikings as time expired, but it was too little too late as the Bulldogs claimed a 20-point victory.
Calexico coach Jamie Chew said, "It was a good win for us,"
Chew was not pleased with the way her girls handled the first half but she commended their coming on strong in the second.
"They had to start boxing out and become more patient on offense," she said. "They (Holtville) made some turnovers and we were able to get some fast breaks."
The Bulldogs play Brawley at home at 7 p.m. Wednesday, a game originally scheduled for Tuesday. The Vikings play at West Shores at 5:30 p.m. Tuesday.
