DeJong will start at second base and bat third in Wednesday's game against the Athletics.

After he was on the bench for each of the last three games, DeJong will re-enter the starting nine Wednesday while Luis Garcia takes a seat against Athletics southpaw Jeffrey Springs. DeJong is slashing .231/.283/.374 overall on the season and looks destined to remain in a utility role unless an injury opens up an everyday job at second base, third base or shortstop.

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.

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.

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.

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.

Arcia was removed from Tuesday's game against the Blue Jays with an apparent injury, Patrick Saunders of The Denver Post reports.

Arcia left the game immediately after slapping a single to right field in the fifth inning, though it's unclear what exactly is bothering him. The Rockies' training staff will evaluate him further and should offer some clarity soon; meanwhile, Kyle Farmer will take over at third base for Colorado.

Hayes is absent from the lineup in Tuesday's game against the Cubs.

Hayes started each of the last four contests for the Reds after being acquired via trade, but he'll take a seat Tuesday. Santiago Espinal will handle third base in Hayes' stead.
