Ethan Roberts News: Sent down to Triple-A

The Cubs optioned Roberts to Triple-A Iowa on Sunday.

Roberts was recalled by the Cubs from Triple-A on April 9 and allowed just one run over his first 6.1 innings in the majors. However, the 27-year-old right-hander struggled in his last outing against the Phillies on Saturday, allowing four runs on three hits and a walk over two innings. Tom Cosgrove was recalled by the Cubs from Iowa to provide a fresh bullpen arm.
