OAKLAND, Calif. (AP) — Madison Bumgarner had a no-hitter through three erratic innings, and then one pitch turned a grinding start into a loss.
Bumgarner matched a career high with five walks and gave up a two-run homer to Josh Donaldson, and the San Francisco Giants fell 4-1 to the Oakland Athletics in the Bay Bridge Series opener Monday.
"I wasn't missing by a big margin," Bumgarner said. "Had a lot of walks and that cost a couple runs. Tried to battle through. The biggest thing today was I wanted to try to go deep and give the bullpen a rest."
Donaldson connected against Bumgarner (4-3) in the fourth, and Yoenis Cespedes added a two-run double against George Kontos in the seventh to extend Oakland's lead.
Bumgarner struck out six and was charged with four runs in 6 2-3 innings. He has lost three of his last four starts, though manager Bruce Bochy felt good about the left-hander's latest outing.
"Our offense has to get it going here a little bit," Bochy said. "That's the kind of pitching we're going to need. It doesn't go down as a quality start, but he left the game with a really good start and that's what we're going to need playing these good clubs. He did all he could. Their guy pitched well."
Buster Posey's groundout in the sixth off Dan Straily (3-2) drove in San Francisco's lone run. Straily allowed four hits and one walk in six innings.
Sean Doolittle pitched two perfect innings and Grant Balfour recorded his 11th save of the season for Oakland, which has won four straight and nine of 10.
"I didn't watch much of the playoffs last year, but I heard the Giants won the World Series," Doolitte said, sarcastically. "So they're the defending champs in your building. That's a crosstown rival. That's a game you get up for. Packed house. The crowd was electric. It was an awesome environment."
The usual sprinkling of green-and-gold clad fans mixed with San Francisco's orange-and-black following that traveled from across the bay to pack the Oakland Coliseum. The announced sellout crowd of 36,067 traded chants of "Let's go Oakland!" and "Let's go Giants!" throughout the cloudy afternoon.
