Riley Cornelio: Everything you need to know

The Nationals optioned Cornelio to Triple-A Rochester after Friday's game against the White Sox. Cornelio made his MLB debut Friday against the Pale Hose, giving up three runs (two earned) on two hits and four walks while striking out one batter over two innings. He'll now be sent back to the minors but could return to Washington later in the year to make a spot start or provide length out of the bullpen.

The Nationals recalled Cornelio from Triple-A Rochester on Friday. Cornelio earned his first promotion to the big leagues after putting up a 2.45 ERA, 1.05 WHIP and 27:8 K:BB through 18.1 innings with Rochester. The right-hander will likely be broken in as a long reliever, but given the lackluster performance of the Nationals' rotation, Cornelio could earn some starts if he pitches well.

The Nationals are expected to recall Cornelio from Triple-A Rochester on Friday, Spencer Nusbaum of The Athletic reports. Cornelio has gotten off to a strong start with Rochester this season, posting a 2.45 ERA and 1.05 WHIP alongside a 27:8 K:BB through 18.1 innings (four starts). His performance will now buy him an opportunity in the big leagues, where he is likely to work out of Washington's bullpen in a long-relief role. He'll be making his MLB debut whenever he gets into a game.
