Leclerc struck out the side during a perfect eighth inning in Sunday's 5-1 win over the Nationals.
Leclerc has looked solid in three appearances since returning from a bruised right index finger earlier this month, striking out six over three scoreless innings while conceding one hit and two walks. It looks as though Leclerc and Keone Kela will function as the primary setup men to closer Matt Bush for the foreseeable future.
