Pineda (finger) was cleared Tuesday to begin a rehab assignment with High-A Wilmington, Bobby Blanco of MASNSports.com reports.
Pineda was placed on the major-league injured list just before Opening Day after suffering a fractured finger on his right hand during spring training. He'll probably be stationed at Triple-A Rochester whenever he's deemed fully healthy, with Keibert Ruiz and Riley Adams remaining up as the catching tandem in Washington.
