Puig, an outfielder who signed last month for a $42 million bonus, was recently promoted from rookie ball to Class A Rancho Cucamonga, where he's hitting .386 (17-for-44) with a homer and four RBIs in 12 games.
Dodgers farmhands joining Puig on the Mesa Solar Sox roster are: pitchers Eric Eadington, Red Patterson and Steven Rodriguez; catcher Gorman Erickson; infielder Rafael Ynoa; and outfielder Joc Pederson.
Pederson (No. 2) and Erickson (No. 15) rank among the Dodgers' top prospects.
The Dodgers also have an open pitcher spot to fill. In addition, Rancho Cucamonga pitching coach Matt Herges will be the pitching coach for Mesa.
