OAKLAND (AP) — Derek Norris hit a two-run homer in the second, Jarrod Parker pitched seven strong innings and the Oakland Athletics beat the San Francisco Giants 6-3 on Tuesday night for their fifth straight victory.

Adam Rosales homered in the eighth for the A’s to snap an 0-for-24 funk since he connected against Kansas City on May 17.

Nate Freiman hit an RBI single and Jed Lowrie and Seth Smith each drew bases-loaded walks as Oakland (30-23) won for the 10th time in 11 games to move seven games above .500 for the first time since April 19.

Hunter Pence homered in the ninth and hit an RBI single in the first to give Mike Kickham a lead before he took the mound for his major league debut.

Parker (3-6) quickly settled into a nice groove. He reached seven innings for the third straight start, earning his second victory over the last five starts after consecutive winless outings.

The 24-year-old Kickham (0-1) worked a clean first inning on nine pitches, hitting 92 mph on his first pitch. He reached 94 several times, too.

But the A’s made contact.

Norris connected in the second for his second home run. Yoenis Cespedes hit a one-out double in the third for the first 10-game hitting streak of his career. That sparked a mound visit by Giants pitching coach Dave Righetti with a runner also on third. Josh Donaldson was intentionally walked, then Lowrie drew a bases-loaded walk to make it 3-1.

Freiman followed with an RBI single to chase Kickham. He was tagged for four runs on four hits in 2 1/3 innings with three strikeouts and four walks as the Giants lost for the seventh time in their last eight road games.

Chad Gaudin, who was in the mix to make the start Tuesday night in place of the injured Ryan Vogelsong, wound up pitching three innings. Manager Bruce Bochy has said Gaudin is too valuable in relief to use him for a spot start.

Kickham might just be up for one more considering the Giants have three upcoming off days and don’t need a fifth starter until mid-June.

He sat at a clubhouse table before the game receiving guidance from Vogelsong, who is recovering from last week’s surgery on his broken pitching hand.

Marco Scutaro singled in the first as designated hitter against his former club. He scored on Pence’s single. After that, Parker retired the next nine Giants batters in order before Brandon Belt’s fourth-inning double.

Scutaro reached on a three-base error by A’s right fielder Chris Young in the eighth but San Francisco failed to capitalize. Pence hit his eighth home run of the year off A’s closer Grant Balfour.

The Giants missed center fielder and leadoff man Angel Pagan at the top of the lineup. He underwent an MRI on his injured left hamstring that revealed bursitis. He hasn’t played since hurting himself in Saturday’s game before his inside-the-park home run to win it 6-5 in the 10th inning against Colorado.
