The proposed trade of outfielder Alex Rios for either San Francisco's Matt Cain or Tim Lincecum rests with the Giants' decision-makers, according to major-league sources. The Toronto Blue Jays will not add major-league pitching to their offer, sources say, and they also are unlikely to move right-hander A.J. Burnett in a separate deal. Adding Cain or Lincecum while subtracting Burnett would be counter-productive for a team trying to build the best possible rotation to compete with the Red Sox and Yankees in the AL East.
