Manager Rocco Baldelli said the injury is considered minor and Kepler is likely to return after the 10 days expire.The Twins selected the contract of Rooker, the 35th overall pick in the 2017 draft by Minnesota, to take Kepler´s spot on the active roster. Rooker has hit .267 with 54 home runs in 259 career minor league games.“He hits the ball very hard,” Baldelli said. “He can hit the ball very far when he does it the way he wants, and he has good at-bats. … We´re facing some tough lefties coming up who have been very good against, especially, left-handed hitters. To be able to pencil Rook´s name in there is very nice.”TRAINER´S ROOMTigers: INF Niko Goodrum missed both games and his third in a row with a sore right side.
