BOSTON — An hour before first pitch Tuesday, Boston Red Sox chief baseball officer Craig Breslow appeared on NESN for a recurring segment on the pregame show and declared he was “absolutely not” giving up on this season.The obvious question lingers: Why not?Four hours later, the Red Sox reached the end of yet another lackluster performance in a 6-1 loss to the Toronto Blue Jays. They dropped to 29-41 and now sit six games back in the American League wild-card race.Despite parity in the AL and 92 games remaining, it becomes harder with each passing day to imagine the Red Sox finding a way back into contention.Tuesday marked the first of 16 straight games the Red Sox will play without a day off. That includes six games on the West Coast with stops in Seattle and Colorado, followed by a four-game home series against the New York Yankees. The grueling stretch will likely make or break the team’s outlook for the rest of the season.“Right now, given we’ve got six weeks or so before the deadline, our focus is on doing everything we can to give ourselves a chance to win the game each night,” Breslow said.It’s too early to wave the white flag, but this Red Sox team has given no indication that it can go on a run that would justify becoming buyers at the deadline. They haven’t won more than three games in a row all season. They haven’t lost more than five in a row, either, but mediocrity abounds.
