Joe Maddon is sticking to his original plan.

After Game 4 of the NLDS between the Cubs and Nationals at Wrigley Field was postponed one day due to rain, the Cubs released their lineup Wednesday morning which is identical to the batting order they released Tuesday.

Javy Baez returned to the starting lineup and Kyle Schwarber, despite committing a double error in left field that could have been costly in the Cubs’ 2-1 victory in Game 3 on Monday, will be back in to the Cubs lineup.

Ben Zobrist is in right field, with Jason Heyward the odd man out against Nationals right-hander Tanner Roark. Heyward is 0-for-18 in his career against Roark.

Right-hander Jake Arrieta, who has been nursing a hamstring injury, will make what could be his final start as a Cub should the team fail to advance in the series. The Cubs, however are looking to put the hammer down on the Nationals, who have lost in the NLDS in 2012, 2014 and 2016. A win tonight would propel the Cubs into the National League Championship Series against the Dodgers.

Arrieta has been nursing a hamstring injury since the end of September, but Joe Maddon said the 2015 NL Cy Young winner is ready to play.

“Jake is pretty much a 100 percenter right now,” Maddon said on 670-AM Tuesday afternoon. “His workouts have been clean, we gave him plenty of time. There’s been no residue or negative effects. Jake is ready to go.”
