(CBS) The Cubs changed their lineup for Game 4 of the National League Division Series on Wednesday afternoon after the Nationals reversed course and decided to start ace right-hander Stephen Strasburg, who had been ill Tuesday.

Jason Heyward has replaced Kyle Schwarber in the starting lineup. He will hit seventh and play right field, with Ben Zobrist shifting from right to left field. Heyward is 15-of-37 in his career against Strasburg. He had been slated to sit when the Nationals had right-hander Tanner Roark lined up. Heyward is 0-of-18 lifetime against Roark.

Jon Jay will play center field again.

Javier Baez will start at second base again after coming off the bench in a Game 3 win because of matchup reasons against Nationals ace right-hander Max Scherzer. Right-hander Jake Arrieta takes the mound for the Cubs on Wednesday.

First pitch is at 3:08 p.m. and can be heard on 670 The Score, which starts its pregame coverage at 2 p.m.

Here’s their lineup:

Jon Jay, CF
Kris Bryant, 3B
Anthony Rizzo, 1B
Willson Contreras, C
Ben Zobrist, LF
