SAN FRANCISCO -- As he high-fived other fans, New Yorker Matt Murphy, 22, slid the ball into the back pocket of his plaid Bermuda shorts. "Glad to be here, man," Murphy told KNTV's Daryl Hawks on his way out of AT&T Park. A team of San Francisco police officers moved in, extracted Murphy from the crowd, and quickly led him through a tunnel and into a secure room. "Murphy and a friend were en route to Australia and in San Francisco for a one-day layover, a Giants spokesman said. They purchased tickets just before the game. He and the friend, dressed in New York Yankees regalia, were razzed by nearby Giants fans. "Hey, this isn't New York!" one shouted. Murphy and his friend just laughed it off before settling into their seats. Murphy declined to make himself available to the media.
