NASHVILLE — The Red Sox reached agreement with Shane Victorino on a three-year deal worth $39 million Tuesday. But will he play right field or center field?

The Red Sox are not necessarily finished constructing their outfield, according to major league sources. General manager Ben Cherington is considering the idea of trading center fielder Jacoby Ellsbury for a starting pitcher, playing Victorino in center field, and signing another player for right field.
