Detroit ? The Detroit Tigers picked up a ninth-inning victory over their biggest rival Friday night.

Now they have to hope they didn’t lose their best pitcher in the process.

David Price allowed five runs and a career-high 13 hits before leaving the game in the seventh inning with a fluke injury. On a single by Alex Gordon that gave Kansas City a 5-4 lead, Price stepped on a discarded bat and tweaked his leg.

“I don’t feel anything right now, but when I stepped on the bat, it rolled and kind of hyperextended my foot,” he said. “It pulled on my hamstring, and when you feel something in your body that you’ve never felt before, you are going to be concerned.

“I don’t know what will happen — we’ll see how I feel tomorrow.”

Detroit, though, tied the game with a run in the seventh and won it in the bottom of the ninth on a throwing error.

Anthony Gose led off the ninth with a double off reliever Yohan Pino, who had been called up earlier in the day.

On the next delivery, Ian Kinsler bunted down the third-base line, and although third baseman Christian Colon appeared to have a better angle, Pino (0-1) fielded the ball and threw wildly to first, allowing Gose to score the winning run.

“I wasn’t sure what was going on — I was just running,” Gose said. “They were trying to make a play and I just wanted to win the game.”

Joakim Soria (2-0) earned the win with a scoreless ninth inning.

The Tigers scored four times in the second despite two high-risk decisions by third-base coach Dave Clark. With the bases loaded and no outs, Andrew Romine singled to right, and Clark sent Nick Castellanos to the plate, even though he didn’t appear to have a chance.

Royals catcher Salvador Perez, though, couldn’t make a clean pickup of Paulo Orlando’s throw, then dropped the ball when he tagged Castellanos. After Gose’s infield single loaded the bases again, Kinsler hit a hard single to right and Clark sent Romine to the plate in another bad-looking move.

This time, Perez caught the ball too far up the first-base line, and Romine was able to slide around his tag, making it 4-0.

Perez made up for two of the runs in the fourth, hitting a long homer to left.
