"We could go either way [on Grandal]," Roberts said. "I'm hopeful there still are ways of maneuvering at-bats so he can open with us. Howie is feeling a little better today, but baseball is still a couple days away. He's a Major League player and he knows how to get through it."
Outfielder Yasiel Puig (tight left hamstring), missed a second consecutive game but is expected to play on Monday. Kiké Hernandez (rib contusion) is also expected to play on Monday. Scott Kazmir, who left Saturday's start early with cramps from dehydration, will make his next start on Wednesday as originally planned.
On the positive side, however, Roberts said shortstop Corey Seager (sprained left knee), who played six innings in a Minor League game on Saturday and had Sunday off, would play in another Minor League game Monday, could play in a Major League game by Wednesday and will play in the Freeway Series.
Reliever Yimi Garcia, who has been dealing with a sore left knee, was expected to pitch in Sunday's game.
