The Nationals optioned Henry to Triple-A Rochester on Saturday.
Despite tossing two scoreless innings in Friday's 14-1 win over the Diamondbacks, Henry is still carrying a 6.00 ERA, 1.67 WHIP and 13:6 K:BB across 12 frames this season. Washington has yet to announce a replacement for Henry on the 26-man active roster, but the team could look to bring a fresh relief arm aboard ahead of Sunday's series finale.
