"Graham Godfrey surely was an unknown quantity to much of the sellout crowd watching him Friday night.

The A's right-hander wound up playing the lead role in Oakland's 5-2 win over the visiting Giants, notching his first major league victory in the opener of the three-game Bay Bridge Series.

In his second big league start, Godfrey limited the Giants to two runs, one earned, over seven innings, walking none and striking out three.

Few A's pitchers get to make their first home start before a packed house, but the announced crowd of 36,067 left quite an impression.

"The thing I'll remember most, a couple times on the mound I could hear A's fans cheering and then Giants fans, and they're just going back and forth," Godfrey said. "Hearing that, it was pretty neat."

It was just the A's third sellout in 33 home games, and Godfrey (1-0) wasn't the only one soaking up the atmosphere.

"I kind of got caught up in watching the fans go back and forth," said A's manager Bob Melvin, who grew up in the Bay Area, played for the Giants and Friday was managing his first game in the rivalry."
