Cubs roster move: Matt Mervis called up, Edwin Rios optioned

This year, Mervis is hitting .286/.402/.560 (26-for-91) with six home runs for Triple-A Iowa. And as first reported Thursday by ESPN’s Jeff Passan, the Cubs are calling up Mervis from Iowa today.

To make room for Mervis on the 26-man active roster, Edwin Rios was optioned to Iowa. Rios didn’t play much for the Cubs this year, going 2-for-20 with a home run.

This means, for now, Eric Hosmer remains on the roster.

Hosmer…
