The Tampa Bay Rays executed the biggest trade in team history Sunday night, sending pitchers James Shields and Wade Davis to the Kansas City Royals for four minor league players, including outfielder Wil Myers, the Royals' top prospect.

The Rays also received right-handed pitcher Jake Odorizzi, left-handed pitcher Mike Montgomery and third baseman Patrick Leonard.

Tampa Bay will send a player to be named later to the Royals, in addition to Shields and Davis.

Shields, who turns 31 later this month, will make $10.25 in 2013. Having him off the books eases the strain on the payroll, especially since pitcher David Price, who won 20 games and the American League Cy Young Award last season, can make up to $10 million in arbitration this offseason.

It's doubtful the money saved on Shields will be put back into the 2013 payroll.

Rays executive vice president of baseball operations Andrew Friedman indicated Thursday during the final day of the Winter Meetings that moving Shields in a blockbuster deal, as many speculated, might not be the case.

Friedman mentioned how the Rays' lack of depth last season at the Triple A level hurt the team during a string of injuries in the first half of the season. Friedman said they would be better prepared in 2013.
