In defense of Cal South, the forecast was for .2 inches on Saturday and .2 inches on Sunday. What Galway Downs received was 1+ inch of rain that started in the early morning and stayed steady throughout the day. This system was a "cut-off" low, which is a unique weather pattern that will cause one area to get inundated and another area a few miles away to receive a few drops and blue sky and clouds. For example:
This station, the closest to Galway Downs reported 1.1 inches on May 7, 2017 -

When games began in the morning, the facility had only received about .2" and all the fields were playable (water logged, but playable) and the dirt roads and lots were passable. By 7 am the rain started falling and falling and falling and didn't stop.
Cal South made the call to stop play at approximately 12:30 / 1pm because the fields were now waterlogged from an additional .5 inches and some fields, such as, field 4 were genuinely underwater. It was the right call. Maybe it could have been called earlier, but based on field conditions at 7am the fields were all playable. One of the reasons Cal South plays at Galway Downs and Silverlakes is because both facilities have made significant investments in their grass fields: drainage, bermuda grass, gopher control, professional field crews, etc., that you don't get with a City or County park.
One other point is some of you have commented that the grass was not good. Don't confuse the fact that Bermuda grass is dormant with and not growing until Spring (this year ... late Spring). The grass is there, just hanging out and waiting to turn green again once the nighttime temperatures reach +55F. The National Cup games were played there and live streamed. For a natural turf surface in late winter/early spring, it looks pretty darn good:
