Hassell (hand) went 2-for-5 at the plate for Double-A Harrisburg in his return from the 7-day injured list Tuesday.
The 23-year-old outfielder was back in action for Harrisburg for the first time since June 11 after an extended absence due to a right hand injury. Before being activated, Hassell played in eight rehab games for High-A Wilmington, going 7-for-27 with six runs and four RBI.
