ANNAPOLIS, MD: Blake Treinen’s debut as the Washington Nationals’ closer came in the ninth inning of Saturday’s Naval Academy Baseball Classic with Boston’s Red Sox in Max Bishop Stadium, home of the Navy’s baseball team. It was an exhibition game, yes, but also the 28-year-old right-hander’s first outing since Nats’ skipper Dusty Baker officially announced that the sinker-balling reliever was the choice to close out games for the defending NL East Champions.
Treinen took the mound with a 4-3 lead.
Mike Miller punched an 0-1 sinker through the right side for a leadoff single.
