Moustakas (thumb) is on track to rejoin the Royals on Saturday, MLB.com's Jeffrey Flanagan reports.
Moustakas went 2-for-8 with an RBI over his first two rehab games with Double-A Northwest Arkansas, and it appears he will play another game with the Double-A squad Friday night. If all goes well, he will likely be called up Saturday and resume his role as the Royals' regular third baseman.
