Cubs' Brian Matusz: Officially added to 25-man roster, starting Sunday

Matusz's contract was selected from Triple-A Iowa and he will start the evening's game against the Mariners.

The left-handed Matusz last pitched in the majors earlier this season as a reliever for the Orioles. After a brief stay in Atlanta via trade, he was designated for assignment and eventually signed a minor league contract with the Cubs. Following two strong starts for Triple-A Iowa, he will now make his first major league start since 2012. The Cubs optioned Justin Grimm to Triple-A in a corresponding move.
