With Corey Seager's expected return by opening day and the acquisition of right-handed hitting center fielder A.J. Pollock, the Los Angeles Dodgers are not expected to be platooning. Seager was limited to 26 games last season and did not play after April 29. ''There is a certain narrative on us platooning last year, and I think that was kind of for survival,'' manager Dave Roberts said Tuesday during his first spring training availability.
