Here is CSN Bay Area's Andrew Baggarly on the news:
"Add Sanchez to the list of Giants who will be doing extra conditioning work this spring, Bochy said. They aren’t just picking on Pablo Sandoval. Sanchez arrived a bit heavier than the club wanted, too."Sanchez is listed at 225 pounds, but with increased playing time coming in his future -- as Buster Posey will likely be positioned at first base more often this season -- the Giants will need him at tip-top shape come Opening Day.
