The Delmarva Shorebirds roster underwent some shuffling today as the Birds added three players. Catcher Justin Dalles returns to the Shorebirds and is activated off the DL. He suffered a concussion in a home plate collision on April 18. Delmarva also added IF Mike Mooney from Frederick and RHP Brent Allar from Aberdeen's roster. Catcher Luis Bernardo is heading from Delmarva to Frederick, catcher Jason Stifler joins Aberdeen's roster and RHP Ryan Palsha has also been placed on Aberdeen's roster. Palsha was 1-1, 4.00 in five games with the Birds. Dalles was off to a good start with Delmarva. A sixth-round pick last June out of the University of South Carolina, he was batting .370 over eight games before his injury. For more background, here is a story including details about Dalles the day after he got hurt.
