The Padres list De Vries (shoulder) as one the organization's eight prospects on the Peoria Javelinas' Arizona Fall League roster, Jeff Sanders of The San Diego Union-Tribune reports.
A right shoulder strain prevented De Vries from playing in any games for Single-A Lake Elsinore after Aug. 17, but his inclusion on the Peoria roster implies that he's expected to be healthy by the time Arizona Fall League play gets underway Oct. 7. De Vries won't turn 18 years old until next month, but the infielder has already established himself as one of the top lower-level prospects in baseball after slashing .237/.361/.441 with 11 home runs and 13 stolen bases in 360 plate appearances in the California League this season.
