The Nationals reinstated Brzykcy (quadriceps) from the 15-day injured list Friday and optioned him to Triple-A Rochester.
The right-hander was sidelined for the first month of the campaign due to a quadriceps strain, but he won't join the big club upon the completion of his four-game rehab assignment. Brzykcy received his first taste of the majors last season with six relief appearances and gave up nine earned runs over 5.2 innings.
