With Marcelo Mayer all but certain to be placed on the injured list with a wrist injury, the Red Sox are summoning David Hamilton from Triple-A Worcester.

After Mayer’s injury, the Red Sox recalled infielder David Hamilton, and though Hamilton will see some time at second, Rafaela’s offense has been too valuable to the lineup. Playing him at second and Duran in center makes the offense stronger. The moving parts have been a challenge for manager Alex Cora much of the season and even more so now.

Red Sox infielder Marcelo Mayer reacts to his unfortunate injury with an uncertain timetable set for his return.
