The Washington Nationals have signed right-hander Victor Arano. While he’s unlikely to be back in the majors for the foreseeable future, he’s a valuable short-term solution for a struggling bullpen. He may even be able to factor into the team’s plans by pitching well enough to be traded for a prospect at the July trade deadline. He could also be a long-term team-controlled reliever, pitching in meaningful games. The return on this signing is promising, with low risk and high reward.
