Barreto (leg) is just 4-for-29 (.138) with a home run and two RBI in nine games with Double-A Midland this month.
Barreto was slowed for a couple days after fouling a ball off his leg May 5, and he has just one hit since returning to the lineup Saturday. Despite the rough stretch with the bat, the 20-year-old remains a top prospect and will continue seeing regular playing time at shortstop for Midland.
