Maxwell signed a minor league contract with the Giants, Matt Eddy of Baseball America reports. Maxwell appeared in 199 games at the major league level from 2012-13 but made just 20 appearances with the Royals last season, and instead spent the majority of the year at Triple-A Omaha. A .224/.311/.417 career hitter at the highest level, he seems unlikely to work into a regular role at any point in 2015, but Maxwell at least provides the Giants with quality organizational depth.
