BOSTON (AP)- The Boston Red Sox have placed designated hitter David Ortiz back on the 15-day disabled list Monday due to lingering problems with a strained right Achilles.
Ortiz, who suffered the injury in mid-July, returned to action in Friday's win over Kansas City, getting two hits and two RBIs, but has not played since due to discomfort.
Ortiz said he'll have an injection in the next day or so and hopes to return this season. He will be a free agent at the end of the season.
Manager Bobby Valentine said the injection would have sidelined him for about seven days so the club decided to put him on the DL.
Outfielder Ryan Kalish was called up from Triple-A Pawtucket to take Ortiz's spot on the roster.
Boston also planned to activate Daisuke Matsuzaka to start the series finale against the Royals on Monday and was going to option reliever Pedro Beato back to Pawtucket.
