First pitch is scheduled for 6:05 p.m. St. Louis time at Nationals Park in Washington, D.C.
With the Nationals sending left-handed starter MacKenzie Gore to the mound, the Cardinals roll out a lineup on Tuesday with Willson Contreras as the designated hitter batting from the four-spot and rookie Jordan Walker batting fifth behind Contreras.
After he drove in a run with a single in the seventh inning on Monday to give him his first hit with a runner in scoring position since May 20, Contreras comes into Tuesday with his average sitting at .201. The 31-year-old has collected six hits in 13 games since the start of June and is 12-for-94 (.
