KANSAS CITY -- What exactly makes the Royals think they can take a pitcher out of Coors Field and change his success? The fact that they've done it before.

The Royals acquired Jeremy Guthrie from the Rockies on Friday, and his numbers have not been good this season, mostly due to poor performances at Coors Field. That makes it two years in a row that the Royals have brought in a pitcher from Colorado midseason. Last May, they acquired Felipe Paulino, and he's been quite the success story.

In 18 relief appearances with the Rockies last season, Paulino was 0-4 with a 7.36 ERA. That includes 6 1/3 innings at Coors Field, in which he allowed six runs on 11 hits, three walks and a home run for an ERA of 8.53.

Paulino pitched much better after coming to Kansas City, posting a 4.11 ERA in 21 games, including 20 starts. And this year, Paulino was enjoying a great season -- 3-1 with a 1.67 ERA in seven starts -- before his season ended following Tommy John surgery.

The Royals are hoping they can work the same magic with Guthrie, whose numbers in Colorado this season include a 1-5 record and a 9.50 ERA.

"It's a good deal," Royals manager Ned Yost said. "Every once in a while, a change of scenery helps somebody. I mean it sure helped Felipe Paulino coming out of Colorado, and we're hoping it can do the same for Jeremy Guthrie."

Trade shifts Teaford back to Royals' bullpen

KANSAS CITY -- The acquisition of veteran starter Jeremy Guthrie means that Everett Teaford will be headed back to the bullpen.

Teaford has gone back and forth between the rotation and the bullpen a few times already this season. He was set to be a member of the Royals' starting staff coming out of the All-Star break, but emergency relief appearances delayed a start. The lefty was slated to make his first second-half start against Minnesota on Sunday, but the Royals opted to replace him with Guthrie.

Teaford will serve as the long man out of the Royals' 'pen.

"It's an important spot and we've kind of been going without one for the last two or two and a half weeks," manager Ned Yost said. "It's important for him to come in like he did the other day against Seattle. You just don't destroy the whole 'pen that way."

Teaford said that it doesn't matter what role he's being used in, as long as he's being used.

"The good thing is I'm still here, so that's one big plus. I don't really care -- whether it's relieving, starting, coming in in the 13th inning, coming in in the fourth inning, whatever -- I really don't care as long as I can help the team," Teaford said.

Yost added that he likes what Teaford has done in a starting role, but the Royals are going to give another youngster, Will Smith, a shot in the rotation.

Smith started on Thursday against Seattle, allowing four runs in 6 1/3 innings for the loss.
