"Giants left-hander Barry Zito was placed on the 15-day disabled list on Sunday with a right mid-foot sprain. He was replaced on the roster by right-hander Ryan Vogelsong, whose contract was purchased from Triple-A Fresno. Vogelsong was added to the 40-man roster, which had one spot open.

Zito was removed from Saturday night's 5-3 victory over the D-backs in the second inning. X-rays were negative and he was expected to undergo an MRI on Sunday to determine the extent of the injury.

Zito left the clubhouse at Chase Field on crutches and with a swollen ankle after the game, which extended San Francisco's current winning streak to four. His personal streak of 356 regular-season starts without having missed one because of injury will end. Zito was next slated to start against the Braves in San Francisco on Friday night. "
