This is a very good deal, Laroche gives us an actual good lefty off the bench and will help us see less of the Lowell statue at 3B. Laroche has a career .901 OPS in his 2nd halves and a career OPS of .857 against righties, if he can hit .270 with some actual power he will be a big upgrade over Kotsay. I hope we see him against most righties and Lowell against lefties and certain righties, Lowell can still hit but he isnt an everyday player anymore because of the hip.
Diaz' career had stalled, he had trouble making even routine plays and was just taking up room on the 40 man roster, this also allows Yamaico Navarro go up to Portland since he was destroying the pitching in Salem (.916 OPS). Strickland may make it as a reliever but losing him is nothing with all the pitching depth in the minors. Another plus to this deal is if Laroche plays well the rest of the way, he could very well be a type B free agent and the Sox could get a pick out of it.
