Detroit ? Jim Leyland is a big fan of Placido Polanco.

Polanco’s tiebreaking single with two outs in the eighth inning gave the Detroit Tigers a 7-6 win over Kansas City on Tuesday night and extended the Royals’ losing streak to six.

Polanco also hit a solo home run and tripled.

“He’s the kind of guy you like working for you every day no matter what field you’re in,” Leyland said. “He comes to work prepared every day.”

Polanco said a compliment like that from someone of Leyland’s stature is a great motivator.

“I work hard every day,” Polanco added. “I keep saying if you take this game for granted and you relax, it will kick you in the backside.”

Polanco is hitting .379 this season and the second baseman’s been among the best in the majors with runners in scoring position for the last three seasons.

“I always want to get a hit,” he said. “I think maybe the pitcher is worried about who is coming up next and then I get better pitches to hit.”

David DeJesus had four hits with a homer and scored three runs for Kansas City, which is 1-7 on the road.

“It was a tough way to lose. We stayed with them but couldn’t get it done,” said DeJesus. “It seems we always score runs, but they come back and overtake us.”

With the score 6-6, Omar Infante singled to lead off the eighth and was sacrificed to second by Neifi Perez. One out later, Polanco singled off David Riske (0-2).

“You can’t fall behind the hitters,” said Riske. “You have to get that first strike. I didn’t do that today.”

Wilfredo Ledezma (3-0) earned the win despite giving up two runs in 2 1/3 innings. Todd Jones allowed one hit in the ninth for his seventh save in seven chances.

Detroit tied the game, 6-6, in the seventh off Joel Peralta when Polanco tripled and scored on Gary Sheffield’s double.

Sheffield continues to struggle after being acquired in a trade from the New York Yankees during the offseason. He’s finding it difficult to adapt to being a full-time designated hitter. He’s hitting .146 with a home run and five RBIs.

“They’re (the fans) pulling for me hard,” Sheffield said. “And when you get in the batter’s box, you probably try too hard. I just need to relax.”

Reggie Sanders’ two-out two-run double in the sixth gave Kansas City a 6-5 lead and capped a four-run outburst.
