This note shouldn't surprise anybody...
'The Blue Jays will look to trade Yunel Escobar but it won't be easy because of his reputation, tweets Jon Heyman of CBSSports.com.'

In getting Mike Aviles in the Farrell deal, the Jays can afford to dump Escobar for a sack of dirty balls. Hell, even without Aviles, they'd happily unload him for nothing. Aviles is a decent middle infielder who could play regularly for the Jays if they're unable to upgrade significantly. He hit .325 as a rookie with KC a few years back (though he only managed .250 last year), so he can definitely do it with the bat.
They now need to address another middle infield position. If the Jays really want to compete next year, Hechavarria can't be in the lineup every day. He doesn't look ready yet. Perhaps they take a run at Scutaro...the same guy they let walk after two great seasons. Ryan Theriot, also of the Giants, is a UFA and would be a slight upgrade over Johnson IMHO.
