Jeremy Guthrie and Jonathan Sanchez both struggled this season after changing leagues.

On Friday, the pitchers were traded for each other.

Guthrie, a former BYU pitcher, had double-digit victories in three straight seasons with the Baltimore Orioles in the American League.

Sanchez threw a no-hitter for the San Francisco Giants and was a part of the Giants' 2010 World Series rotation.

Guthrie opened this season with the Colorado Rockies and Sanchez with the Kansas City Royals, but both struggled in their new leagues.

"I'm excited," Guthrie said. "The first thought is disappointment that I couldn't hold up my end of the bargain in Colorado and help that team win games, which I think they were built to do at the start of this year.

"But as I looked at what was in my future and I look at the Royals, I see a perfect fit there. I'm excited to play with the guys that are down there. It's a young core of great baseball players and an organization that has been lauded recently for the moves and the progress they've made, and I really hope to come in there and be a large part of good things that we can do here in the near future."

Sanchez was designated for assignment Tuesday by the Royals. The 29-year-old left-hander is 1-6 with a 7.76 ERA in 12 starts this season. A seven-year major league veteran, he is 39-52 with a 4.50 ERA, 420 walks and 772 strikeouts in 186 games (130 starts).

Sanchez threw a no-hitter against San Diego in 2009 and the Royals traded away Melky Cabrera to get him last November in what turned out to be one of the worst trades in team history. Sanchez was winless in his final 11 starts with Kansas City.

Guthrie, a 2002 first-round pick of the Cleveland Indians, was the Orioles' opening day starter 2008-10 and surpassed the 200-inning mark in each of the past three seasons.

He is scheduled to make his first Royals' start Sunday against the Twins. The Royals' rotation has a 26-40 record with a 5.43 ERA and has worked the fewest innings, 467 2

3, of any major league rotation this season.

"I'm looking to hopefully being a workhorse, someone that can go out there and be there for the team whenever he's needed," Guthrie said. "I have been blessed with a lot of health in my career, which is really important: to be able to go out there and your team can depend on you, to go out there and throw the innings and give them a chance to win."

ASTROS, BLUE JAYS STAGE 10-PLAYER DEAL: The Houston Astros acquired closer Francisco Cordero and outfielder Ben Francisco as part of a 10-player trade with Toronto on Friday.

Houston will also receive four minor leaguers in the deal — right-handed pitchers Joe Musgrove and Asher Wojciechowski, left-handed pitcher David Rollins, catcher Carlos Perez and a player to be named later.

The Blue Jays, who entered Friday at 45-47 and in last place in the AL East, will receive pitchers Brandon Lyon, J.A. Happ and David Carpenter from Houston.

"This is a very good deal for us," Houston general manager Jeff Luhnow said. "Once again, we are adding depth to our minor league system with quality young players. We really feel this will help us moving forward and are extremely excited about the players we've added to our organization."

Cordero has 329 career saves, second among active players to the New York Yankees' Mariano Rivera (608). In 794 career relief appearances, the 37-year-old Cordero has a 3.28 ERA and has reached 40 or more saves in three seasons. Cordero is 3-5 with two saves in 41 appearances for Toronto this season.

Francisco is hitting .244 in 23 games for Toronto in 2012. He has a .259 career average with 45 home runs in 483 career games with Cleveland, Philadelphia and Toronto.

Lyon, a former Taylorsville High School star, signed a three-year, $15 million contract with the Astros in December 2009. He struggled with tendinitis in his right biceps in 2011 and appeared in only 15 games. He's 0-2 with a 3.25 ERA in 37 appearances this season.

The left-throwing Happ is 7-9 with a 4.83 ERA in 18 starts this season, his third in Houston. Carpenter, playing for the Astros' Triple-A affiliate in Oklahoma City, was 0-2 with a 6.07 ERA in 30 relief appearances for the Astros this season.

ORIOLES ACQUIRE INFIELDER FROM METS: The Baltimore Orioles acquired infielder Omar Quintanilla from the New York Mets for cash on Friday.

Quintanilla was designated for assignment by the Mets on Tuesday when they activated outfielder Jason Bay from the disabled list.

The 30-year-old Quintanilla batted .257 with a homer, four RBIs and a .350 on-base percentage in 29 games for New York this season. He was called up from Triple-A Buffalo and filled in admirably at shortstop while starter Ruben Tejada and a pair of backups were injured.

"He knew coming in what his job was, and that was to play as well as he could until Ruben came back, and he did," Mets manager Terry Collins said. "When I talked to him when we sent him out the other day, I told him: 'This team owes you a tremendous thank you for the job you did.' Not just because, hey, he was our last resort. That was not it. He came up and played as good as anybody we've had. So he has a lot to do with where we sit today."

Quintanilla is expected to join the Orioles on Saturday, and a corresponding roster move will be made. A .218 career hitter in 592 big league at-bats, he also has played for Colorado and Texas.

In another move, right-hander Brad Bergesen, designated for assignment by the Orioles on Wednesday, was claimed off waivers by Arizona. He has not pitched in the majors this season.
