The Royals placed Rios on the disabled list on April 14 after he was hit by a pitch and sustained a fracture in his left hand. He was hitting .321 with one home run and eight RBIs when the injury occurred.
Rios, 34, recently completed a rehab stint at Triple A Omaha, where he played four games and had three hits in 17 at-bats, including a home run. Rios said the minor league stint "went well," but said he knows he will still have to deal with some discomfort.
"On some occasions, there is going to be some discomfort. I'm just going to have to deal with it," he said. "Overall, though, I was able to swing at 100 percent. We achieved our goal."
Kansas City signed Rios to a one-year, $9.5 million deal over the off-season with an option for 2016. He spent the 2014 season with the Texas Rangers.
The Royals, which were 7–0 when Rios sustained the fracture, have gone 21–18 since. They began a three-game series with the Cubs on Friday.
