The Boston Red Sox placed outfielder Darnell McDonald on the 15-day disabled list Sunday.
The 33-year-old, who is suffering from a left oblique strain, is batting a mere .179 with two home runs and eight RBI in 26 games this season.
The club selected first baseman Mauro Gomez, 27, to the active roster from Triple-A Pawtucket.
To make room for Gomez on the 40-man roster, Boston transferred Jacoby Ellsbury to the 60-day disabled list. The runner-up in 2011 American League MVP voting was placed on the 15-day disabled list on April 14 with a right shoulder subluxation.
