Nationals general manager Mike Rizzo has denied that the team has a target date for Stephen Strasburg's debut despite reports that he'll start in Washington on June 4th. "That hasn't been decided yet, although you did announce that he's pitching on the 4th," Rizzo said. "No, that hasn't been determined yet. There are factors that will be involved when we announce it. And even when we announce it, it's not going to be settled on until after a couple days after he starts his last start in Triple A." Strasburg will make his next minor league start Saturday at Class AAA Syracuse.
