The Boston Red Sox signed first baseman Nathaniel Lowe to a one-year contract Monday, two days after he was released by the Washington Nationals. To make room on the roster, the Red Sox placed outfielder Rob Refsnyder on the 10-day injured list with a strained muscle on his left side.

League sources said late Sunday night that the club was close to finalizing a contract with Nathaniel Lowe, whom they hope will provide a boost at first base, specifically against righthanded hitters.

Lowe was granted his release from the Nationals on Saturday, and he has now found a new home in Boston.
