On the Adam LaRoche deal: The Red Sox have been searching for ways to upgrade their sliding offense for weeks. This deal has been on the table for three weeks, and after losing their fourth straight game on Tuesday and declining to trade Clay Buchholz for Victor Martinez, Theo Epstein took LaRoche.The Red Sox will work LaRoche, Mike Lowell and David Ortiz into the first-base, DH and third-base spots, with Kevin Youkilis moving back and forth between first and third. Boston's team OPS has declined every month this season, and in the past four years, LaRoche's second-half OPS is .938.The Red Sox felt they had to move Wednesday because the Pirates had a deal to send LaRoche to another team in exchange for a better package than Argenis Diaz and Hunter Strickland, but Boston was willing to take on LaRoche's entire salary.
