Oakland, Calif. ? Daric Barton wasn’t bothered by the booing he heard in the second inning after dropping Miguel Olivo’s fly ball in foul territory. When Olivo homered two pitches later, Oakland’s first baseman could only shrug his shoulders.

“It’s not the first time it’s happened in my life, and it’s not going to be the last,” Barton said. “It’s part of the game and you have to have a short-term memory and get over it.”

Barton did that, going 3-for-5 with a single, double and triple in the Athletics’ 6-5 victory over the Kansas City Royals on Saturday.

Kurt Suzuki singled home Chris Denorfia with the go-ahead run in the seventh inning, and the A’s knocked around the Royals’ bullpen for the second straight day to deny starter Zack Greinke his fourth win of the year.

Six players had at least two hits for Oakland, which set a season high with 16 hits a night after getting 15 hits against Brian Bannister and four relievers.

“We expect that out of ourselves,” Barton said. “We’re always having people on base, it’s just whether or not we’ve got the guys in at the right time. If you look at the pitchers we’ve faced so far and the pitchers we’ve beat, there’s nobody we can’t beat.”

A day after scoring eight runs in the eighth inning of a 13-2 win, Oakland rallied from a 4-0 deficit and scored three times in its final three at-bats.

Joey Devine (2-0) pitched two shutout innings of relief to earn the win. Huston Street recorded the final four outs for his fifth save in six chances.

Jose Guillen also homered for the struggling Royals, who managed only four hits over the final seven innings. Kansas City has lost three straight and four of five after opening the season 8-5, its best start since 2003.

“Obviously we didn’t play up to our capabilities today,” manager Trey Hillman said.
