SURPRISE, Ariz. -- Alex Rios said that Monday's MRI of his lower back showed nothing serious beyond a muscular issue, leaving him optimistic that he will be ready for Opening Day on April 1.
"There's nothing. There's just pain. There's nothing to be worried about. And I think it's just going to take time to heal," Rios said. "No worries. It's going to be fine."
Manager Robin Ventura had expressed the desire to use Rios in a game or two before the White Sox broke camp on Wednesday. But with Rios missing his fourth straight Cactus League contest Tuesday, his target was more on one of the two exhibition games Friday and Saturday in Milwaukee.
"It depends how I feel," Rios said. "I believe that I've made pretty decent progress from yesterday to today. It was easier to get out of bed and do some stuff. But certain moves, I still feel a little pinch but I should be fine. I feel looser and we'll see what happens."
Rios reiterated that the problem started Saturday when he was lifting weights and that he felt nothing during his participation for Team Puerto Rico in the World Baseball Classic.
"We shouldn't be worried," Rios said. "I'm not worried. I'm going to be ready."
