What happened: The Washington Nationals selected the contract of right-handed pitcher Eddy Yean. In a corresponding move, the club designated Robert Hassell III for assignment.
Why it matters: The roster adjustment brings fresh pitching depth to a Nationals club aiming to stabilize its bullpen. Moving on from Hassell marks a notable shift in the organization's outfield prospect pipeline.
By the numbers: Washington holds a 46-44 record this season, averaging 5.3 runs per game while allowing 5.2.
What to watch: Yean joins the pitching staff as the Nationals prepare for their scheduled home game against the Houston Astros.
