Ryu (groin) will debut Saturday, MLB.com's Ken Gurnick reports.
He was originally slated to make his Cactus League debut Friday, and while he was only pushed back one day, this is in line with the trend of delayed returns that have become so common for Ryu over the past two seasons. Until he logs exhibition innings over multiple starts this spring, it will be hard to have any faith in the southpaw providing value at the outset of the season.
