Kumar Rocker gave up four runs — three earned — in 3 1/3 innings to take a loss to the Mariners on Saturday.
Rocker struggled to stay ahead of hitters, and threw 38-of-68 pitches for strikes before leaving. There wasn’t a ton of hard contact, but the 25-year-old’s poor command doomed him Saturday night. Rocker has alternated quality starts with shaky ones, which isn’t a huge surprise for a rookie hurler. Rocker will try and bounce back Friday, but that start is against the Dodgers. Fantasy managers shouldn’t take the chance if they don’t have to.
