Manager Joe Maddon doesn't anticipate any major changes in the Cubs lineup Friday night after the Nationals opted for Stephen Strasburg to start Game 1 of the National League Division Series in place of injured Max Scherzer.
"There might have been one adjustment only," Maddon said.
The only minor difference is that outfielder Albert Almora Jr. is 2-for-6 with two doubles lifetime against Strasburg but hasn't faced Scherzer, whose first start in the NLDS could be pushed back to Monday's Game 3 because of a right hamstring injury.
"I faced (Strasburg) enough, but it's a new season and I'm in a new division," said Heyward, who also pointed to Paul Goldschmidt of the Diamondbacks going hitless in 11 career at-bats against Jon Gray of the Rockies before hitting a home run in Wednesday's NL wild-card game.
Roster update: The Cubs' NLDS roster must be submitted by 10 a.m. Friday, but Maddon wouldn't reveal any details.
Arrieta said his leg felt better, which lines him up for a start Tuesday in Game 4, if necessary.
"I've been on repeat (champions) as a player," Baker said. "The feeling that you have, and the feeling of confidence and not the panic, that's an advantage to them somewhat that they have been there.
"But we've been close ourselves. So this is going to be a heck of a postseason."
"Having played all the way through a Game 7 of the World Series does count for something," Doolittle said. "That's not to say there are a lot of guys in here with a lot of playoff experience, a lot of guys who have won some World Series.
"We do have enough experience that neither one of these teams is going to get caught off guard by the energy of the situation."
