Does Cal not have lights? Is that why there wasn’t a a double header on Saturday or a longer rain delay last night?

Yes, MT pointed out that there are no lights at Cal's stadium. However, a doubleheader could have been managed on Saturday or Sunday,
if the first game was played before 2:00pm/2:30pm. Say, 11:00am first pitch for Game #1 and then 2:00/2:30pm for Game #2 (which wouldn't conflict with Pac-12 TV broadcast).

Cal hosts non-conference tournaments and NCAA regionals at their stadium, so they have managed to play more than one game in a day.
