Mariners' Julio Rodríguez placed on 7-day injured list with concussion after being hit in helmet‎

Seattle center fielder Julio Rodríguez, who was removed from the Mariners’ game against the Los Angeles Angels on Thursday night after being struck by a ball in the back of the head, was placed on the 7-day injured list on Friday with a concussion. In a corresponding move, the Mariners selected the contract of infielder/outfielder Miles Mastrobuoni from Triple-A Tacoma. Rodríguez was running from first to second on a ground ball in the first inning of Thursday's 1-0 win when first baseman Nolan Schanuel fielded it and tried to throw to second to start a double play.
