The Detroit Tigers remain the only unbeaten team in baseball, although their latest victory came after the bullpen surrendered five runs in the ninth inning.

Torii Hunter drove in five runs and the bottom of lineup combined for six hits and five runs scored, helping the Tigers take a 7-1 lead entering the ninth.

The Tigers improved to 4-0 with a 7-6 win over the Orioles today at Comerica Park.

Phil Coke entered the ninth and allowed two hits, a walk and three earned runs in one-third of an inning. Al Alburquerque gave up one hit and an earned run and Joe Nathan allowed two hits and one earned run before getting the final two outs for his first save as a Tiger.

With runners on first and third with one out, Nathan got Nelson Cruz to strike out swinging on a 3-2 slider. Chris Davis hit a fly ball to left to end the game.

“Davis, we went in,” Nathan said. “We went inside with two fastballs, got him to pop one up.”

Ausmus, a catcher for 18 seasons in the major leagues, said it can be difficult for a reliever to come in with a big lead.

"The offense, at that point, has nothing to lose,” Ausmus said. “They can just go up there swinging, knowing the pitcher has to throw strikes and get outs.

“I’m not overly concerned about it right now. I certainly don’t want to go out and have games like that on a regular basis.”

Nathan agreed.

“Do we want to get sharper?” he said. “Do we want to be at our best right now, and always? Absolutely. There’s not a day we come in here going, ‘Ah, I don’t feel like being that sharp today.’”
