Gray seems to have plenty left in the tank as he approaches his 37th birthday in November, but it’s not the first time he’s hinted that he doesn’t see himself going the Justin Verlander route. He was also especially frustrated with the way his final start ended, suggesting that manager Chad Tracy should have trusted him to get more outs instead of pulling him in the fifth. “I don’t know what the future holds for me,” Gray said. “I do know that I walked off that mound with my chest back and my chin up, and I can definitely be proud that I left it all out there until the ball was taken out of my hands.” Gray will be eligible for free agency this winter, likely by opting out of his contract after the Red Sox pick up their portion of a $30 million option.
