Carpenter, 26, made his Major League Baseball debut last year with the Cubs, posting a 2.79 earned-run average in 10 games. Selected by Chicago in the third round of the 2008 draft, the right-hander gave up three runs and struck out eight in 9 2/3 innings of relief.
Epstein, who won two World Series championships in nine seasons as the Red Sox’s general manager, left Boston in October to become the Cubs’ president of baseball operations. He had one year remaining on his contract in Boston, entitling the team to compensation that wasn’t determined at the time of his resignation.
Commissioner Bud Selig’s office had reviewed the compensation issue. Epstein said in a statement on the Cubs’ website that the teams “were able to reach agreement on their own without intervention from MLB.”
The Red Sox placed two-time All-Star relief pitcher Bobby Jenks on the 60-day disabled list to make room for Carpenter on the 40-man roster, according a news release from the American League team.
The Cubs will also receive a player to be named from Boston under the agreement.
