CHICAGO -- Shortstop Corey Seager reported continued progress in his rehabilitation from a lower back sprain in Los Angeles on Thursday, said Dodgers manager Dave Roberts, who is hoping to get him back for the World Series.

"He had a good day today," said Roberts. "He was happy today. I think he swung the bat off the tee. Trainers said it was a very positive day. He responded well to running yesterday, normal soreness. But to be able to ramp it up is good."

Seager was injured sliding into second base in the Game 3 clincher of the National League Division Series presented by T-Mobile in Arizona. He had an epidural injection for the pain, was completely sidelined for a week and left off the roster for the NL Championship Series presented by Camping World.

The World Series, presented by YouTube TV, is scheduled to start next Tuesday. In Seager's absence, Roberts has started Charlie Culberson and Chris Taylor at shortstop.
About that music
There has been significant musical gamesmanship between the clubs during batting practice of the NLCS.
At Dodger Stadium, when the Cubs took batting practice, the Dodgers sound system shifted from upbeat contemporary sounds to soft rock.
Not to be outdone, the Dodgers were met by silence during batting practice followed by organ music at Wrigley Field.
That prompted Joc Pederson to bring out to the field a portable speaker loaded with the Dodgers' regular batting practice music. Pederson set up the speaker against the batting cage and the Dodgers took their swings with self-provided musical accompaniment.
Doc on Granderson
Roberts said he's not oblivious to the struggles of outfielder Curtis Granderson, who struck out four times in Game 4. While Roberts wouldn't' speculate on future starting lineups before Game 5, he acknowledged that the slumping Granderson hasn't produced.
"It is about performance," said Roberts. "I know that he's preparing, it's just not working out. Obviously, there's got to be some adjustments. He knows this, it's on the breaking balls. They're going to spin him. He has to get them off the breaking ball."
