Earlier in the morning, a motorcycle driver had a tough time negotiating the slick surface on the interchange from eastbound I-8 to northbound I-15.
The wheels of his motorcycle slipped out from under him as he banked on the turn and he fell to the road, injuring his arm. He was transported to an area hospital and his bike was hauled off by a friend, according to SDFD.
The Padres say the rain cancellation will be made up in September. The regularily scheduled game on Sept. 2 will move from 5:40 p.m. to 7:10 p.m. to better accommodate a double-header.
"Tickets for today's game are valid for the same seats at the new game time, and should be used for ballpark entry on September 2," the Padres said in a release.
There are no refunds for rescheduled games, but tickets can be exchanged prior to the rescheduled game.
The park's Saturday post-game fireworks show was also canceled.
