Pablo Sandoval, the San Francisco Giants player who sparked a report of sexual assault Friday morning, had been socializing with fans the night before at Motiv on Pacific Avenue in Santa Cruz, the bar manager confirmed Sunday.

About 4:30 a.m. Friday, the Santa Cruz County Sheriff's Office received a complaint that Sandoval, 25, had sexually assaulted a woman he met earlier in downtown Santa Cruz, according to a statement Saturday by Lt. Fred Plageman.

The woman met a small group of people and went with them to Seascape Beach Resort in Aptos, where the alleged assault occurred, Plageman said.

Sandoval, a San Francisco resident, cooperated with the investigation and was questioned but not arrested, Plageman said.

His attorney, Eric Geffon, said the sexual activity had been consensual. No details about the alleged assault or victim were released.

Motiv manager Isaac Cook said Sandoval had been hanging out at the bar for at least two hours Thursday night with two men. He said he believed the men were his brother and his agent.

Cook said they left about 1:15 a.m. and that he didn't see any women leave with them.

"Women and men were coming up to him all night, taking pictures and talking to him," he said. "He was very lucid and friendly. We didn't have any problems."

It's not yet clear whether any charges will be brought against Sandoval.

As is normal procedure, the Sheriff's Office will complete its investigation and forward a report to the county district attorney, who will decide whether to file charges.

Sandoval was leading the Giants in home runs and RBIs when he fractured a bone in his left hand May 1. He had surgery two days later and is expected to play four or five games in the minor leagues before rejoining the Giants' active roster.
