Bobby Valentine won't go away. Speaking to NBC Sports Network last night in his first extended interview since being fired by the Red Sox [team stats], Valentine accused David Ortiz [stats] of using his strained right Achilles as an excuse to quit on the season because he didn't want to play after the white flag-waving Aug.?25 trade with the Dodgers. "David Ortiz came back after spending about six weeks on the disabled list, and we thought it was only going to be a week. He got two hits the first two times up, drove in a couple runs. We were off to the races," Valentine told Bob Costas. "Then he realized that this trade meant that we're not going to run this race, and we're not even going to finish the race properly, and he decided not to play anymore. I think at that time it was all downhill from there." Ortiz, who didn't respond to a message last night, was one of the few players who didn't have a rocky relationship with Valentine. And after aggravating the injury Aug.?24, he received a plasma-rich platelet injection in an attempt to return in September. Valentine also took veiled jabs at the baseball operations staff, noting that general manager Ben Cherington or one of his assistants "always was in the manager's office" and alluding to their refusal to blame injuries for the team's performance. But he steered clear of blasting principal owner John Henry, chairman Tom Werner and president Larry Lucchino. "I'm not going to do anything to make their life any more miserable than I've already made their life for a season," Valentine said. "They died almost 100 times last year, and no one needs to die that much."
