Rodón (3-0) allowed three hits and one run, which raised his ERA from 1.06 to 1.17. The left-hander walked two and broke Tim Lincecum’s franchise record for most strikeouts through a pitcher’s first four starts with the team with 38. Lincecum had 35 Ks in 2009.

The Giants’ prized offseason acquisition, Rodón pitched out of jams in the first and fourth, and worked around Sheldon Neuse’s RBI single in the third to remain unbeaten with his new club.

Flores had five RBIs in 10 games during San Francisco’s 11-game road trip then nearly matched that in his first two at-bats against Oakland. The Giants designated hitter had an RBI double off A’s starter Daulton Jefferies in the second after Brandon Crawford’s leadoff walk, then hit a three-run drive in the third to put the Giants ahead 5-1.

Jefferies (1-3) allowed five runs and four hits in four innings.

Slater flew out as a pinch-hitter in the fifth then hit a three-run drive off Jacob Lemoine in the seventh.

Seth Brown had a pinch-hit RBI double for Oakland. The A’s have lost four of six.
