Yes, it's probably this one:
White Sox Pursuing Jason Schmidt?
Of couple of ESPN columnists seem to have independently arrived at the same trade rumor in their blogs in recent days. Buster Olney's source is a "talent evaluator" while Jayson Stark got word from "an executive who has heard this talk."
According to Olney and Stark, the White Sox would trade Brandon McCarthy and Brian Anderson to the Giants for Jason Schmidt. The Sox would then acquire a center fielder in a separate trade.
