The Cardinals optioned Prieto to Triple-A Memphis on Friday.

Prieto went 1-for-6 with five strikeouts during his first cup of coffee in the majors. He could get another opportunity before the end of this month but will head back to Memphis for now.

Chisholm (knees) is in the starting lineup and batting sixth for Friday's game against the Blue Jays.

Chisholm was removed from Thursday's game versus Houston in the fourth inning due to bruised knees. Testing after the game came back clean, and Chisholm apparently feels good enough to play in Friday's American League East showdown with Toronto. Chisholm has a .938 OPS over the last 30 days.

Sosa is not in the lineup for Friday's contest versus the Tigers.

It looks to be a routine day off for Sosa, who had started each of the previous 11 tilts. Curtis Mead will cover first base in Sosa's stead.

Bazzana went 3-for-4 with a walk, a home run, two RBI and an additional run scored for Triple-A Columbus on Thursday.

Twenty games into his stay at the highest level of the minors, Bazzana launched his first home run for the Clippers in style, as his two-run shot was a walk-off job. The first overall pick in the 2024 First-Year Player Draft has endured some struggles in his first go-around at Triple-A and entered the night batting just .182 over 19 games for Columbus. However, Bazzana has exhibited a keen eye, posting a .415 on-base percentage.

Keaschall went 4-for-5 with an RBI, one stolen base and two runs scored in Thursday's 11-8 loss to the White Sox.

Keaschall had gone five games without a multi-hit effort prior to Thursday, but he busted that slump with the first four-hit performance of his young career. He's had no trouble against major-league pitching over his first 33 games, slashing .328/.418/.508 with four home runs, 21 RBI, 18 runs scored, nine stolen bases and 10 doubles across 141 plate appearances. Keaschall should continue to see a near-everyday role at second base in the final few weeks of the campaign.

Clemens went 2-for-5 with a solo home run in Thursday's 11-8 loss to the White Sox.

Clemens has seen his playing time slip early in September. He's gone just 6-for-31 (.194) at the plate over his last 11 games, with his ninth-inning homer Thursday being his first extra-base hit in that span. For the season, he's at a .210/.280/.427 slash line with 15 homers, 41 RBI, 39 runs scored and two stolen bases across 101 games between the Twins and the Phillies. Clemens and fellow left-handed hitter Edouard Julien have been competing for most of the playing time at first base lately.

Medical testing on Chisholm's knees came back clean after leaving Thursday's game versus the Astros, and he hopes to be in the lineup Friday against the Blue Jays, Brendan Kuty of The Athletic reports.

Chisholm injured both of his knees while in the field Thursday and exited the game in the fourth inning having gone 0-for-2 with a strikeout. It's unclear exactly what testing was done, and the team has not released any additional details since Chisholm was originally diagnosed with contusions.

Frazier went 1-for-3 with a solo home run in Thursday's 4-3 win over the Angels.

Frazier hit the first of the Royals' four solo shots to spark the comeback win. He continues to see a starting role between second base, designated hitter and the corner outfield, and he's earned a strong share of playing time by going 12-for-38 (.316) over his last 11 games. Frazier is up to a .270/.322/.373 slash line with six homers, 38 RBI, 37 runs scored and eight stolen bases over 116 games between the Royals and the Pirates this season.

Chisholm exited Thursday's game against the Astros with contusions to both of his knees, Pete Caldera of The Bergen Record reports.

Chisholm appeared to suffer an injury on a tag play at second base in the third inning, though at the time it didn't seem as though both legs were affected. The positive news is that he appears to have avoided serious injury, but Chisholm could undergo further imaging to determine the full degree of the injury.

Chisholm exited Thursday's game against the Astros with an apparent leg injury, Erik Boland of Newsday reports.

Chisholm was slid into by Jose Altuve as he applied the tag on a stolen base attempt in the third inning. Chisholm jogged off the field with a limp but took his at-bat in the top of the fourth inning before departing. The 27-year-old appeared to be favoring his knee or ankle, but more details should emerge after the game or at some point Friday.
