Soto, from Santo Domingo, Dominican Republic, has been placed on the seven-day disabled list. Team officials say no timeline has been set for his return.
If the ankle is fractured, he would need two weeks of rest and treatment before being re-evaluated. In that scenario, Soto would likely not need surgery, and could be back in the lineup by sometime in June.
The highly-rated prospect is considered by a top international scouting director as the “best hitting prospect” he’s ever seen. The 18-year-old Soto is batting .360 in 23 games for low Single-A Hagerstown.
He had 31 hits, five doubles, three homers, 15 runs and 14 RBIs to begin the season. Last season, he hit .368 in 51 games. Prior to the injury, Soto had connected on five hits in his past four games.
