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.”
