OAKLAND, Calif.—The San Francisco Giants finished their spring across the bay in Oakland on Saturday afternoon. The third game of the Bay Bridge Series went to the Athletics, who were victorious in a 4-1 victory in front of 21,157 fans at the Coliseum.

Matt Cain polished off his spring with a loss, in which he gave up just one earned run in five innings pitched. The earned run came off the bat of Khris Davis, who homered to left for his second of spring to open up the third inning. Trouble came in the outfield later in the third when Denard Span was charged with two errors, which allowed Jed Lowrie to round the bases completely, bringing in Marcus Semien in the process to make it 3-0.

Cain ends spring training with a 1-2 record, pitching 17 innings after he was sidelined for a month with a minor surgery to his throwing arm. “I was very pleased with the job that he did. He made a couple of mistakes, but overall, it was a great effort and a great tune-up,” added manager, Bruce Bochy.

He enters the regular season looking the Giants’ fifth man on the rotation if he can remain healthy. Cain mentioned that the cyst on his throwing arm hadn’t been bugging him until it reputed and after the surgery that cleaned it out he was ready to go within a week but was held back to try and avoid infection.

Buster Posey didn’t suit up for the Giants and was a late scratch due to illness and was taken out of Friday’s night game early as a precaution. Bochy expected him to be in the lineup as San Francisco’s Designated Hitter. Posey is questionable to start on Monday, according to Bochy, “whatever it is, I hope he’s good to go on Monday.”

The story of the day for the Athletics was starting pitcher, Felix Doubront exiting the contest after just one inning pitched. The expected fifth starter for the A’s was relieved of his duties after complaining about tightness in his left arm. Non-roster invitee, Eric Surkamp took over and shut down the Giants. He gave up just two hits in seven innings while striking out seven and walking one. Surkamp was reassigned to minor league camp following Saturday’s game.

Matt Chapman homered in the eighth inning to extend the lead to 4-0. The shot to left was his sixth of the spring and his fifth RBI in the last five games.

The Giants lone run came in the ninth inning when Ehire Adrianza hit a solo shot to right field for his first of spring training to make it 4-1.

The Giants begin their season on Monday, as they will travel to Wisconsin to take on the Milwaukee Brewers in the Brewer’s home opener.
