JUPITER, Fla. — The Washington Nationals’ rookie-level Gulf Coast League affiliate pitched seven-inning no-hitters in both ends of a doubleheader Sunday.

Facing the GCL Marlins at the teams’ shared spring training home, right-handed prospect Joan Baez opened the first game with six innings, allowing a walk and striking out seven. Jose Jimenez walked one in the seventh to close a 4-0 victory.

Baez is among the organization’s top pitching prospects. He improved to 2-0 with a 1.47 ERA in four appearances (three starts) with the GCL Nationals.

In the second game, Jared Johnson walked one in four innings, and Gilberto Chu closed with three perfect innings in a 1-0 win. It was only the second pro start for Johnson, a 17th-round draft pick last month from Palm Beach State Junior College.

They were the first no-hitters in the GCL this season.
