MINNEAPOLIS — Yu Darvish said on Wednesday that he is on track to start Sunday for the Texas Rangers, a day after neck stiffness forced him to be scratched from a start against the Minnesota Twins.The right-hander went through a full workout at Target Field and threw off flat ground without any lingering issues from an apparent rough night of sleep Monday night.Darvish was feeling better and had his range of motion back by late Tuesday afternoon after a precautionary MRI exam showed nothing troubling. “He’s on schedule for Sunday,” manager Ron Washington said. “There’s one thing about Yu Darvish: If he’s not 100 percent, he’ll let us know.”The Rangers, especially those who have tried to pitch with neck stiffness, didn’t question the Darvish’s inability to pitch Tuesday because of a second bout with the ailment this year. No player on the team understands his body better than Darivsh, pitching coach Mike Maddux said.Maddux said that he had to be scratched twice during his career with a stiff neck.“You just can’t throw,” he said.Darvish didn’t address the media about his injury, even though every other injured Rangers player this season, including first baseman Prince Fielder, has fielded questions about their health.Washington said that the Rangers aren’t too preoccupied about this neck troubles going forward.“Yu Darvish is just a different animal. He doesn’t want to have a reason why he didn’t do well,” Washington said.
