Okajima was non-tendered by Boston following the season, and he reportedly considered joining a club in his native Japan. It appears that he elected instead to return to the Red Sox, where he pitched for four seasons after moving stateside in 2007.
Okajima turned 35 years old on Christmas. He allowed left-handed hitters to hit to a .284 average in 2010, raising his career mark against them to .214. He posted a 4-4 record with a 4.50 ERA.
