It has been a busy day for trades in Major League Baseball.

First the Blue Jays pulled off a massive, eight player, three way deal to get Colby Rasmus from St. Louis in exchange for Edwin Jackson and other pieces. Now we are getting word that the New York Mets are about to move Carlos Beltran to the defending champion San Francisco Giants for stud pitching prospect Zack Wheeler.

Beltran, a 38-year old outfielder, had been on the block for months, and a move was an absolutely certainty. If the return is accurate and the Mets do in fact get Wheeler, as Buster Olney has reported via twitter, then the Mets have gotten more than many people expected them to get in a deal for Beltran. 

With the Jays and Giants both acquiring center fielders Wednesday, the number of suitors left for Tampa Bay Rays outfielder B.J. Upton is thinning. San Francisco had expressed interest in Upton, saying they liked his defense in their big ballpark. Still in play for his services are Atlanta, Washington, Cleveland, and Philadelphia, whom reportedly thought they were in play for Beltran before he was ultimately traded to the Giants.
