Cardinals manager Oliver Marmol said Wednesday that Arenado (shoulder) will report to the team's spring training complex in Florida on Friday to begin his rehab, John Denton of MLB.com reports.

Arenado will first work on strengthening his injured right shoulder, and if he shows sufficient improvement in that regard, he will be cleared to begin a rehab assignment with the club's rookie-level Florida Complex League affiliate. The veteran third baseman remains without a timeline to return from the 10-day injured list, but a target date for his return should become clearer as he ramps up his rehab. Nolan Gorman has been filling in at third base for St. Louis since Arenado went down with the injury Friday.

The Astros transferred Paredes (hamstring) from the 10-day injured list to the 60-day IL on Wednesday, Brian McTaggart of MLB.com reports.

The transaction frees up a spot on the 40-man roster for right-hander Spencer Arrighetti (thumb), who was activated from the 60-day IL ahead of his start Wednesday against the Marlins. Paredes has a significant right hamstring strain but has decided against surgery and will attempt to return later this season. He is now eligible for activation Sept. 19.

Arcia won't start in Wednesday's game against the Blue Jays due to a right elbow injury, Kevin Henry of The Denver Gazette reports.

Arcia went 1-for-2 with a base hit before he was lifted for a pinch runner in the bottom of the fifth inning of Tuesday's 10-4 loss due to the elbow issue. According to Henry, interim manager Warren Schaeffer said that Arcia is set to undergo an MRI on Wednesday, and the Rockies will wait and see how the veteran infielder feels following Thursday's off day before determining whether he'll require a stint on the injured list. Kyle Farmer will cover third base in Arcia's stead Wednesday.

Barger is out of the lineup for Wednesday's game against the Rockies.

With a lefty (Kyle Freeland) on the hill for the Rockies and with the Blue Jays wrapping up their series in Denver with a day game after a night game, Toronto manager John Schneider likely viewed it as an opportune time to give the left-handed-hitting Barger a breather. Barger had started in each of the Blue Jays' last 15 games, slashing .219/.275/.438 with three home runs, 12 RBI and 10 runs during that stretch.

Muncy is out of the lineup for Wednesday's game versus the Cardinals.

Muncy went 4-for-5 with a pair of home runs in Tuesday's 12-6 victory in his second game back from the injured list, but he'll get a breather during Wednesday's matinee. Alex Freeland will cover third base and bat ninth for the Dodgers.

House went 1-for-3 with a walk and three RBI in Tuesday's loss to the A's.

The rookie third baseman had a productive night, even though the Nationals were on the wrong end of a 16-7 rout. House hasn't homered in 14 straight games, slashing .224/.231/.245 over that stretch with a 1:15 BB:K, but a rebuilding Washington squad will live with some growing pains from the 2021 first-round pick.

Barger went 1-for-5 with a solo home run in Tuesday's win over the Rockies.

Starting at third base and batting cleanup, Barger went back-to-back with Vladimir Guerrero in the sixth inning to help blow the game open in a 10-4 victory. It was Barger's 17th homer of the year, but the 25-year-old has cooled down a little of late. Over the last 15 games, he's slashing .219/.275/.438 with a 29.0 percent strikeout rate, although he's also produced three long balls, 10 runs and 12 RBI.

Mauricio is out of the lineup for Wednesday's game versus the Guardians.

Mauricio had drawn nine straight starts at third base against right-handed pitching, but he'll begin Wednesday's contest on the bench as the Guardians send righty Gavin Williams to the bump. Brett Baty will patrol the hot corner and bat ninth for the Mets.

Machado went 3-for-5 with a double, a walk and two runs scored in Tuesday's 10-5 extra-innings win over the Diamondbacks.

Machado has hit safely in 12 of his last 13 games, going 24-for-54 (.444) in that span. The third baseman had cooled off to begin August, going just 3-for-15 over his first four games of the month before his bat roared back to life Tuesday. On the year, he's at a stellar .302/.362/.505 slash line with 20 home runs, 29 doubles, 72 RBI, 68 runs scored and 10 stolen bases through 114 contests.

Muncy went 4-for-5 with two home runs, four RBI and three runs scored in Tuesday's 12-6 win over the Cardinals.

Muncy missed over a month with a left knee bone bruise. He went 0-for-3 with a walk and a strikeout in his return Monday before providing a large chunk of the Dodgers' offense in a 17-hit barrage Tuesday. The third baseman has started each of the last two games but may see some occasional time off if the Dodgers want to keep switch hitting prospect Alex Freeland involved at the hot corner. With the big game, Muncy is up to 15 homers this season while adding 59 RBI, 42 runs scored, four stolen bases and a .258/.380/.481 slash line across 83 contests.
