The Red Sox have acquired veteran infielder Mike Aviles from the Royals for infielder Yamaico Navarro and minor league pitcher Kendal Volz. Aviles finished fourth in Rookie of the Year voting in 2008, when he batted .325 for the Royals. The Red Sox view Aviles as veteran infield insurance, and it signals that they have some doubts about when Jed Lowrie will be back, and how effective he will be when he returns.
