The Kansas City Royals acquired right-handed starting pitchers James Shields and Wade Davis and a player to be named or cash considerations from the Tampa Bay Rays in exchange for minor league outfielder Wil Myers, right-handed pitcher Jake Odorizzi, left-handed pitcher Mike Montgomery and third baseman Patrick Leonard.

Shields, who will turn 31 on December 20, has established himself as one of the premier pitchers in the American League. He followed up an All-Star campaign in 2011, in which posted a 16-12 record with a 2.82 ERA and finished third in the A.L. Cy Young voting, by posting a 15-10 record with a 3.52 ERA in 33 starts with Tampa Bay last season. In 227.2 innings, Shields allowed 208 hits, walked 58 and struck out 223, just two shy of his career best set in 2011 and the third-most in the league. Shields is joined by the Mariners’ Felix Hernandez, the Dodgers’ Clayton Kershaw and the Tigers’ Justin Verlander as the only four pitchers in baseball to record at least 220 strikeouts in the last two seasons.

The 6-foot-4, 215-pound right-hander has compiled an 87-73 career record with a 3.89 ERA in 218 games (217 starts) all for the Rays since making his debut in 2006. Since tossing 124.2 innings in 21 starts during his rookie campaign, Shields has won at least 11 games, made at least 31 starts and topped the 200-inning mark in six straight seasons. He joins the Jays’ Mark Buehrle, the Giants’ Matt Cain, the Yankees’ CC Sabathia and Verlander as the only five pitchers in baseball to post at least 200 innings in six straight seasons. In 2011, his 11 complete games were the most by a Major League pitcher since Arizona’s Randy Johnson had 12 in 1999.

The Royals gave up Myers, who turns 22 today, and was the 2012 Baseball America, USA Today and Topps Minor League Baseball Player of the Year after hitting a combined .314 with 37 home runs and 109 RBI in 134 games for Northwest Arkansas (AA) and Omaha (AAA). He was the Royals’ third round selection in the 2009 June Free Agent Draft.

The 22-year-old Odorizzi went 15-5 with a 3.03 ERA in 26 outings (25 starts) for Northwest Arkansas and Omaha in 2012 before making two starts for the Royals in September, going 0-1. He was acquired by Kansas City in a six-player trade with the Milwaukee Brewers on December 19, 2012.

Montgomery, 23, split his season between Omaha and Northwest Arkansas, posting a 5-12 record with a 6.07 ERA in 27 starts. He was the Royals’ supplemental first round selection (36th overall) in 2008.

The 20-year-old Leonard batted .251 with 14 home runs and 46 RBI in 62 games for Burlington (R) in 2012. He was the club’s fifth-round pick in the 2011 Draft.

The Royals also get the 27-year-old Davis, who made a combined 64 starts for the Rays from 2009 to 2011 before pitching exclusively in the bullpen for Tampa Bay in 2012. He went 3-0 with a 2.43 ERA last season, allowing 48 hits and 29 walks with 87 strikeouts in 70.1 innings. The 6-foot-5, 225-pounder made 29 starts in both 2010 and 2011 and finished fourth in the American League Rookie of the Year voting after posting a 12-10 record with a 4.07 ERA in 2010. Davis is 28-22 with a 3.94 ERA in 118 career outings, including 64 starts. He is 25-22 in his career as a starter with a 4.22 ERA, including an 8-2 mark with a 3.38 ERA in 30 games (18 starts) against A.L. Central foes.
