Morse is shooting for a June return when the Nationals play American League teams. He more than likely would be the team's designated hitter in those games.
"I think he can DH around the eighth of June, when we go Interleague," Johnson said. "Hopefully, that will give him a month before he has to throw from the outfield. Hopefully, that injury will heal. If he is throwing well enough in the next three weeks and can hit, he'll be able to play."
