The Nationals released right-handed reliever Trevor Rosenthal on Sunday after his struggles continued in his second stint in the major leagues this season.

Rosenthal had a 22.74 ERA in 6 1/3 innings over 12 appearances this season. In his final game for Washington on Saturday, he allowed three earned runs and three walks without recording an out as the Nationals blew a four-run lead in a 13-9 loss to the Braves.

'"He's got great stuff,'' Nationals manager Dave Martinez said. "He just couldn't find the strike zone.''
