Rios (hand) is expected to begin a rehab assignment in "a couple days," according to manager Ned Yost, 610 Sports Radio's Josh Vernier reports. This suggests that a return in early June could be possible for Rios, who would then presumably return to being the everyday right fielder. Continue to monitor his status to make sure he actually does begin a rehab assignment in the coming days. Paulo Orlando and Jarrod Dyson will continue to get the starts in right field until Rios returns.
