Dustin Pedroia will be sidelined for a "few weeks" with a thumb injury that has landed him on the disabled list. The Red Sox second baseman showed up at Fenway Park on Friday afternoon with a cast immobilizing the thumb. "I'll be back in a few weeks," said Pedroia, who was injured diving for a ball Tuesday night against the Athletics in Oakland. "It's not like I'll be out all year. Guys will weather the storm. We'll be fine." Boston called the injury a "hyperextension."
