Oakland, Calif. ? Jonathan Broxton lost his command and lost the game on his final two pitches.

Broxton hit Jonny Gomes on the first pitch he threw with the bases loaded in the 12th inning, forcing Jemile Weeks home for the winning run in the Kansas City Royals’ 5-4 loss to the Oakland Athletics on Wednesday.

Moments earlier, Kansas City’s new closer (0-1) plunked rookie cleanup hitter Yoenis Cespedes on the first pitch to load the bases, prompting a mound visit from pitching coach Dave Eiland.

“I wasn’t very good today, with the walks and everything else. It started out good but I just didn’t have it,” said Broxton, hoping to return to the form that made him one of baseball’s most feared ninth-inning pitchers a couple of years back. “One was a sinker and one was a four-seam fastball.”

It marked the third time the A’s won on a game-ending hit by pitch in Oakland history and first since Olmedo Saenz on July 20, 2002, against Texas.

“You can hit me four times if we win,” said Gomes, nearly plunked earlier by a heater from Kelvin Herrera. “We have to write that down and keep it in the back of our minds because 98 mph could end your season.”

Coco Crisp’s RBI groundout earlier in the 12th tied it at 4 after Billy Butler doubled home the go-ahead run in top half of the inning against Andrew Carignan (1-1).

A day after rain shortened the Royals’ 3-0 win following seven-plus innings, fans got their share of ball in the finale.

These teams meet again June 1-3 in Kansas City, and suspended A’s slugger Manny Ramirez could be in the lineup by then. He’s eligible to play on his 40th birthday May 30 if all stays on track.

For now, Kansas City heads home for the first time since the start of spring training in mid-February at 3-3, but without the same momentum it would have had with a second winning road series after taking two of three at Los Angeles.

“It’s been a good road trip in terms of our pitching staff. The bullpen did a phenomenal job to keep us in it as we waited for the big hit,” manager Ned Yost said. “We got it with Billy’s double.”

Oakland closer Grant Balfour pitched a scoreless ninth and 10th. He allowed Alcides Escobar’s leadoff single in the 10th and a two-out walk to Jeff Francoeur on four pitches before striking out Mike Moustakas.
