Kershaw had made up his mind at the start of the season."Usually we wait to the offseason to kind of make a final call, but I think almost going into the season, we kind of knew that this was going to be it,” Kershaw said. “So I didn’t want to say anything in case I changed my mind."But over the course of the season, just how grateful I am to have been healthy, to be out on the mound and be able to pitch, I think it just made it obvious that this was a good sending-off point. And it is. I’ve had the best time this year. It’s been a blast.”Kershaw missed the majority of the first half of the season due to a toe surgery, but showed his class on the mound since the All-Star break.
