After two fatal injuries to horses, jockeys at Bay Meadows refused to ride following the second race Thursday, citing unsafe conditions caused by steady rainfall at the Bay Area track the past week.

“I think they thought the undersurface was too slick,” said Jack Liebau, track president. “Well, (Russell) Baze didn’t think so, but the others felt there was too much slop.

“If the jockeys don’t feel it’s safe to ride, we won’t race,” he added. “That’s my policy and has always been my policy.”

Liebau said track maintenance personnel immediately went to work scraping the excess moisture off the surface, and he expects racing to resume as normal on Friday
