The Twins this morning placed right-hander Zebby Matthews on the 15-day Injured List with a right shoulder strain. Matthews, 25, was recalled from Class AAA St. Paul on May 18 and has made four starts for the big league club, going 1-1 with a 5.21 earned-run average. He has fanned 25 and walked eight in 19 innings.

Four days after the Twins lost Pablo López to a shoulder injury that will sideline him for the next two months, they lost another starting pitcher. Zebby Matthews was placed on the 15-day injured list Sunday because of a right shoulder strain.

Chris Paddack was once the biggest question mark in the Twins' rotation, but now they're counting on him to stay healthy and keep rolling.
