Jon Heyman of CBSSports.com reports that the Red Sox have signed infielder Nick Punto to a two-year, $3 million contract. The Red Sox didn't wait long to fill Jed Lowrie's spot on the bench. The 34-year-old was limited to just 63 games in 2011 due to injury, but batted .278/.388/.421 with an .809 OPS over 166 plate appearances with the Cardinals. Known as a skilled defender, Punto should do well as a backup at shortstop, second base and the hot corner. He can earn an additional $500,000 with incentives.
