The America’s Cup World Series practice races went uninterrupted Tuesday despite the inexplicable actions of a fully clothed man who jumped off a pier at Fort Mason and swam toward an area where sailors were working out.

The man, who was not identified by police, jumped into the Bay about 3:30 p.m. After the Coast Guard pulled him from the frigid waters, he became combative, police Sgt. Daniel Greely said. Coast Guard officials restrained him before turning him over to police.

As Fire Department officials helped load the man into an ambulance, he struggled to free himself and was grunting loudly. Greely said authorities suspected the man was intoxicated.

Instead of the drunk tank, however, the man was sent to a hospital for a mental health evaluation, Officer Albie Esparza said Wednesday.
