* PADRES: Benito Santiago threw his batting helmet in anger after grounding out Tuesday night, and it hit manager Greg Riddoch, knocking him groggy.
"It was a freak thing," Santiago said. "But on TV they're already saying that I tried to hit him, that I did it on purpose. I threw it down and it bounced wild. I apologized to Greg."
Riddoch, who seemed to be in good spirits, said he was looking away when the helmet hit him.
"I had my head turned. I saw it somehow out of the corner of my eye, but I got dinged, hit in the temple."
