Stewart is not in the lineup for Friday's game against the Mets.

Stewart started two straight games upon his promotion Monday but has now been out of the lineup for two straight tilts, though he did appear as a pinch hitter Wednesday. Spencer Steer is handling first base in Friday's series opener.

Contreras' suspension for his actions in the Cardinals' Aug. 25 games versus the Pirates has been reduced from six games to four games and he will begin serving the suspension Friday, Derrick Goold of the St. Louis Post-Dispatch reports.

Contreras was tossed from the game after arguing about the strike zone and then tossed his bat in the direction of the home-plate umpire, striking hitting coach Brant Brown instead. He'll sit out the weekend series against the Giants and the first game of next week's series versus the Mariners before being reinstated Tuesday. With Contreras unavailable and Alec Burleson (wrist) on the 10-day injured list, the Cardinals don't have a traditional first baseman on the active roster. The club could elect to shift Nolan Gorman to first base and play Cesar Prieto or Jose Fermin at third base for the next four contests.

Yorke went 1-for-3 with two RBI and a double Thursday against the Dodgers.

Yorke made his second start since being promoted to the majors at the start of September, both of which have come against lefties. He was lifted in the eighth inning for defensive purposes, but Yorke delivered a key double that knocked in two in the fifth frame prior to his departure. Yorke looks to be on the small side of a platoon for the time being, but he could force his way into more at-bats if he continues to hit.

Contreras went 3-for-4 with a triple and four RBI in Wednesday's 5-1 win against the Athletics.

Contreras plated St. Louis' first two runs with a single in the third inning. He capped the Cardinals' scoring in the contest with a two-run triple in the eighth. Contreras finished with his first multi-hit game over his past 10 contests, and his four RBI on Wednesday were as many as he'd recorded during that 10-game stretch. Contreras is up to 78 RBI on the campaign, establishing a new career-high mark.

Bernabel (knee/quadriceps) will start at first base and bat sixth in Wednesday's game against the Giants.

Bernabel will return to the lineup for the first time since Saturday, after a left knee and quad bruise confined him to the bench for the previous three contests. The Rockies turned to Kyle Farmer (two starts) and Orlando Arcia (one start) at first base while Bernabel was out.

Smith isn't in the lineup for Wednesday's game against the Rockies, Susan Slusser of the San Francisco Chronicle reports.

After extending his hitting streak to five games with a pair of singles Tuesday, Smith will grab a seat on the bench Wednesday with Rafael Devers covering first base and Wilmer Flores serving as the Giants' designated hitter.

Vaughn isn't in the lineup for Wednesday's game against the Phillies.

Vaughn has cooled off quite a bit after getting off to a hot start with the Brewers, and he'll now head to the bench for the second time in as many games while Jake Bauers starts at first base for Milwaukee.

Steer (leg) will start at first base and bat sixth in Wednesday's game against the Blue Jays.

Steer will return to the lineup after a two-game absence due to a minor leg injury. Top prospect Sal Stewart had started at first base in both of the previous two contests while Steer managed the leg issue, but the rookie could end up shifting into more of a utility role moving forward, assuming Steer is able to maintain health.

Stewart is out of the lineup for Wednesday's game against the Blue Jays.

Following his promotion from Triple-A Louisville on Monday, Stewart started at first base in the first two games of the series with Toronto and went 2-for-8 with a run scored. Though he'll be on the bench Wednesday while Spencer Steer (leg) checks back in at first base following a two-game absence, Stewart could still have a path to at least semi-regular playing time in September while moving between second base and designated hitter.

Burleson hopes to take batting practice in the coming days after an anti-inflammatory injection alleviated discomfort in his injured right wrist, Derrick Goold of the St. Louis Post-Dispatch reports.

If Burleson is able to take batting practice soon, he could avoid a rehab assignment and be activated from the 10-day injured list when first eligible Sept. 8. Burleson is second only to Ivan Herrera on the Cardinals with a wRC+ of 120 this season.
