From ESPN's Jonah Keri:
Texas Rangers trade Tanner Scheppers and Michael Kirkman to the New York Mets for Carlos Beltran
New York Yankees trade Eduardo Nunez to the Seattle Mariners for Erik Bedard
Cleveland Indians trade Nick Weglarz to the Los Angeles Dodgers for Hiroki Kuroda and $2 million
Detroit Tigers trade Wade Gaynor and Bruce Rondon to the Chicago Cubs for Aramis Ramirez, Kerry Wood and $4 million
Los Angeles Angels trade Fabio Martinez Mesa and Trevor Reckling to the San Diego Padres for Heath Bell
"This is a team with the cognitive dissonance to believe that four years and $81 million for Vernon Wells is a good idea, and that Jeff Mathis' pitcher-like offense is adequate given his defensive skills. Even in those two cases, the Angels could easily use internal options like Mike Trout and Hank Conger to address the problem. That leaves the bullpen as the most likely area to upgrade. Like most American League contenders, the Angels are set at the closer position, with rookie Jordan Walden doing an excellent job. But the pen gets thin after veteran lefty Scott Downs and strikeout-reaper Rich Thompson. Bell could be the final piece to a sneakily scary Angels team, especially if they make the playoffs: Good luck scoring runs against Jered Weaver and Dan Haren in the first seven innings, or Bell and Walden in the last two … assuming Bell's performance and declining peripherals hold up away from Petco Park, that is."
"Martinez Mesa cooks with gas and led the Midwest League in strikeouts last year, but he also struggles mightily with command and is on the mend from a shoulder injury. Getting a potential Carlos Marmol plus a moderate-upside starter for two months of Heath Bell seems a favorable return, even if Bell ends up qualifying for Type A free agent status at year's end."
