"I'm not so much worried about it, but I guess you can call it that, but I just want him to stay positive and stay upbeat," Gardenhire said. "I just want to let him know we're with him out there."
Gardenhire, though, said he was confident that Nishioka will be just fine, and said he's not worried about Nishioka in his first season since playing eight years in Japan.
"I think he's having fun," Gardenhire said. "This is a dream of his to come over here and play. No one said it was going to be easy, and I don't think anyone thought it would be easy. There's a lot of work to do and he'll continue to do that."
