"Right now, he's pitching in Las Vegas," Rangers manager Ron Washington said. "We'll see how we get through the next two days against the Royals and we'll see who's pitching on Sunday."
Washington has Miles Mikolas slated to start Monday's series opener against the Mariners, followed by fellow right-hander Nick Martinez on Tuesday, allowing them both to pitch on five days' rest. When Holland will make his season debut has yet to be determined.
"We'll let Holland do what he's got to do in Vegas and then we'll make that decision," said Washington.
