They already have one of the best outfield prospects in baseball in David DeJesus, all there looking for right now is pitching, so i propose...
Red Sox get:
Carlos Beltran ($11.0 in 2004, arbitration/free agency/contract in 2005)
-$1.5 in 2004
Royals get:
Freddy Garcia ($7.0 in 2004, arbitration/free agency/contract in 2005)
Derek Lowe ($4.5 in 2004, free agency/contract in 2005)
+$0.5 in 2004
Mariners get:
Johnny Damon ($8.0 in 2004, $8.5 in 2005)
+$1.0 in 2004
The Red Sox get there man, and even though they add on another free agent to be, they get him for this year, which is "the year" remember...
The Royals get two stud righties for the 04 season, and find themselves with the best rotation in the AL Central, they give DeJesus the chance he deserves and everyones happy in KC.
The Mariners get Damon, who as a player I love, but whose contract I can't stand. The Mariners are only taking on so much money with Garcia leaving, they get the offense they need and they can finally move Ichiro back to a spot in the line-up he belongs in, something other than the lead off spot.
