The Boston Red Sox placed designated hitter David Ortiz on the 15-day disabled list with a strained right Achilles tendon before Wednesday night's game against the Chicago White Sox.
Manager Bobby Valentine said a second opinion concurred with the team's original report. Ortiz was injured rounding second base in Monday night's win.
Valentine said it would be a week to 10 days before Ortiz resumes playing, so the team elected to put him on the DL.
Ortiz has 23 homers and 58 RBI, and is currently on an 11-game hitting streak. He also has at least a hit and a walk in 10 straight games, breaking Ted Williams' club record set in 1950.
To fill his spot on the roster, Boston recalled Mauro Gomez from Triple-A Pawtucket.
