The Los Angeles Dodgers placed shortstop Corey Seager on the 10-day injured list as expected Thursday, two days after he came away with a left hamstring strain in a game against the Los Angeles Angels. There is no timetable on Seager's return but the injury has been downgraded from a more severe Grade 2 strain to somewhere between a Grade 1 and Grade 2 strain, MLB.com reported. After a slow start to the season following hip and elbow surgeries that cost him almost all of last year, Seager was starting to find his groove.
