TODAY IN CUBS HISTORY: Ray Burris throws a two-hit shutout and the Cubs defeat the Expos at Jarry Park 2-0 in just one hour, 45 minutes in front of a tiny gathering of just 2,782. It happened 50 years ago today, Wednesday, Sept. 15, 1976.

The Cubs lineup was not available at posting time. Please check BCB social media for the Cubs lineup.

Braves lineup:

Kevin Gausman, RHP vs. Martin Perez, LHP

Kevin Gausman’s last start was just bad, so hopefully it’s been flushed and he starts fresh tonight.

Gausman faced the Braves June 2 in Atlanta and allowed four runs in six innings, which is… not

great, but not awful either. Matt Olson homered off him, one of three career long balls Olson has off Gausman.

Overall current Braves are batting .240 (24-for-100) against Gausman.

Martin Perez is 35 now, but having an under-the-radar solid year for Atlanta.

In eight starts since Aug. 1 he has a 2.18 ERA and 1.282 WHIP and only two home runs allowed in 41.1 innings.

His only appearance against the Cubs this year was one inning of scoreless relief May 13 in Atlanta. The Cub who has faced him most is Alex Bregman (10-for-42, a double, nine walks).
