Seager played six innings on Monday in a minor-league game and was scheduled to do the same on Tuesday. He will rest on Wednesday before returning to the big-league schedule.
Roberts also sounded optimistic about catcher
Grandal was cleared to throw and take some swings on Monday.
"It was a step in the right direction," Roberts said. "He came in feeling better today, pretty good after yesterday. And we're going to ramp up the workload today."
"Today's better than yesterday," Roberts said. "But we still don't have him out there doing baseball activities. But we're encouraged that today he feels better."
