Duffy will take over as the everyday third baseman for the Giants, Andrew Baggarly of CSN Bay Area reports. Duffy had been starting to take playing time away from Casey McGehee, but should be taking over full-time after McGehee was designated for assignment Sunday. The right-handed Duffy is batting .299/.330/.402 over his first 97 at-bats of the season, and his new role makes him worth a look in deeper and NL-only formats.
