Jackson to Cards, Rasmus to Jays in big swap

White Sox get Frasor as 11 players change teams in three-way

The White Sox, Blue Jays and Cardinals completed what amounted to a three-team trade on Wednesday that sent right-hander Edwin Jackson to St. Louis and outfielder Colby Rasmus to Toronto, and nine other players changing teams, with as many as three more to be named later.

The White Sox got reliever Jason Frasor and pitching prospect Zach Stewart from Toronto in exchange for Jackson and third baseman Mark Teahen. About two hours later, the Blue Jays sent Jackson to the Cardinals, along with relievers Octavio Dotel and Marc Rzepczynski and outfielder Corey Patterson and three players to be named later or cash, and received Rasmus, left-handers Brian Tallet and Trever Miller and right-hander P.J. Walters.

"We feel that this deal strengthens us in a number of key areas," Cardinals general manager John Mozeliak said. "Trades of this nature are never easy to make, but we felt that it was important to solidify a number of areas on our ballclub to better position ourselves for what looks to be a highly competitive divisional race."

Jackson, 7-7 with a 3.92 ERA in 19 starts, was widely known to be a trade chip for the White Sox because of Chicago's six-man rotation and Jackson being eligible for free agency after the season. The White Sox were Jackson's fifth team in nine seasons. The Cardinals became his third team on Wednesday.

Trade Include

"It's definitely not my first time being traded," Jackson said after learning about the first trade, the one that sent him to Toronto. "It's just tough to leave a great group of guys, but at the end of the day it's nothing that I can control. The only thing I can do is go out and pitch for whatever team I'm with and try to help that team win."

Rasmus, 24, was batting .246 with 11 home runs and 40 RBIs. In his three Major League seasons, the 2005 first-round Draft pick has a .259 average with 50 home runs and 158 RBIs in 385 games.

A look at which players went where in the 11-player trade between the Cardinals, Blue Jays and White Sox:
Cardinals Blue Jays White Sox

Edwin Jackson Colby Rasmus Zach Stewart
Corey Patterson Brian Tallet
Marc Rzepczynski Mark Teahen

Miller, 32, has one save in 39 games with an ERA of 4.02. Tallet, 33, had an ERA of 8.31 in 18 games for St. Louis.

Rzepczynski, 25, was 2-3 with a 2.97 ERA and 10 holds for Toronto this season. He has been used as both a reliever and starter since debuting with Toronto in 2009.

Dotel, 37, had a 3.68 ERA in 36 games for the Jays this season. He has 106 career saves, combining for a career-high 36 in 2004 with Houston and Oakland.

Patterson, 31, is batting .252 this year with six homers, 33 RBI and 13 steals. His career marks include a .253 average with 118 homers and 218 steals. He hit a career-high 24 homers for the Cubs in 2004 and he swiped a career-best 45 steals for Baltimore in 2006.

Frasor, who has a club option for next year in his contract, is 2-1 with a 2.98 ERA in 44 games. He has allowed just one earned run in his past seven appearances, six of which lasted at least an inning.

Stewart, 24, was a third-round pick of the Reds in the 2008 MLB First-Year Player Draft. Cincinnati dealt him, Edwin Encarnacion and Josh Roenicke to Toronto for Scott Rolen at the Trade Deadline in 2009. Stewart, ranked by MLB.com as the Jays' No. 4 prospect, made his big league debut in June for the Blue Jays, going 0-1 with a 4.86 ERA in three starts. He was 5-5 with a 4.20 ERA in 16 starts with Double-A New Hampshire.

Teahen hit .203 with three homers and 11 RBIs in 51 games for the White Sox. Despite being healthy recently, he had been sharing time with Brent Morel at third base and making the occasional pinch-hit appearance. He was acquired from the Royals in November 2009.

"Mixed emotions for sure. Obviously I'm disappointed in the way it worked out here, I wanted it to go a lot different," said Teahen, who had one hit in his last 18 at-bats. "Injuries and opportunities didn't line up, but it is what it is, it's part of the game and I'm excited to move on to the next step of my career."
