Los Angeles Dodgers setup man Blake Treinen was placed on the 10-day injured list with right shoulder discomfort Friday, more than a week after his last appearance. Manager Dave Roberts said earlier this week that Treinen's arm was "barking" following the last time he pitched on April 14 against Cincinnati. Treinen is 1-1 with a 3.00 ERA in three appearances this season, with five strikeouts and no walks.
