Chapman went 2-for-4 with two RBI, a double and a walk in Monday's 9-5 loss to Atlanta.

Chapman drove in the Giants' first run on an RBI single in the first inning and added an RBI double in the ninth. The 32-year-old has recorded two hits in back-to-back outings, and Monday's game marked his third multi-hit effort since returning from a sprained right hand July 5. The third baseman has appeared in 12 games this month, slashing .213/.275/.319 with nine runs scored, five RBI, two doubles and one home run across 51 plate appearances.

House went 3-for-4 with a double, two runs scored, an RBI and a stolen base in Monday's win over the Reds.

The 22-year-old continues to impress in his first look at major-league pitching. Over 13 games in July, House is slashing .327/.333/.500 with three doubles, two homers, one steal, eight runs and eight RBI, although his 1:10 BB:K is a bit of a concern. A first-round pick in the 2021 First-Year Player Draft, House is cementing his status as the Nationals' future at the hot corner.

Riley (abdomen) is expected to return from the 10-day injured list for Tuesday's game against the Giants, David O'Brien of The Athletic reports.

The third baseman went through an extensive workout Monday and felt good, but Atlanta will wait and see how Riley feels Tuesday morning before activating him. The 28-year-old was heating up prior to straining his abdomen earlier this month, slashing .327/.340/.551 over his last 12 games with five doubles and two home runs.

Suarez went 1-for-4 with a solo home run and a walk in Monday's 6-3 loss to the Astros.

New opponent, same result -- Suarez is still dialed in at the plate. Over four games since the All-Star break, the third baseman has slugged five homers while going 6-for-14 with three walks and eight RBI. He's up to 36 long balls on the year, good for the National League lead and just two behind Cal Raleigh for most in the majors. Suarez's power surge has his slugging percentage up to .605 and his OPS at .933, and he's added 86 RBI, 64 runs scored, 18 doubles and a stolen base over 99 contests this season.

Shaw went 2-for-4 with a three-run home run in Monday's 12-4 loss to the Royals.

Shaw is showing some signs of life lately, as he's now riding a modest four-game hitting streak, and he's gone 6-for-11 during the stretch. The rookie is still batting just .216 overall, and the Cubs may target a veteran third baseman before the trade deadline as his replacement, but Shaw does have the talent to get hot. His fantasy value is higher in dynasty formats at the moment, though the 23-year-old could still deliver some production down the stretch this year depending on his role.

Baty went 1-for-3 with a two-run homer, a walk and an additional run scored in Monday's 7-5 win against the Angels.

The 25-year-old opened the scoring for his team with a 404-foot, two-run blast off Los Angeles lefty Tyler Anderson in the fourth. This marks the first long ball Baty has hit off a southpaw this season, as he appears to be emerging from a strong-side platoon role into an everyday one, drawing consecutive starts against left-handers. Through 255 total plate appearances, Baty is slashing .237/.295/.431 with 33 RBI and 26 runs scored.

Cardinals president of baseball operations John Mozeliak said Monday that he will approach Arenado in the week leading up to the trade deadline to ask for the third baseman's preference if a trade possibility surfaces, Derrick Goold of the St. Louis Post-Dispatch reports.

Arenado has a full no-trade clause and used it to shut down a potential trade to the Astros over the offseason. It's uncertain what the 34-year-old's appetite is for waiving the clause at the trade deadline, nor is it clear what level interest there will be in Arenado from contenders. Arenado has had a fine year defensively at third base but further regressed at the plate, slashing only .241/.299/.381. He's owed $42 million over the next two seasons, with the Rockies being responsible for $5 million of that.

Durbin is not in the starting lineup for Monday's game against the Mariners.

Anthony Seigler will bat eighth and make the start at third base against Seattle right-hander George Kirby. Durbin has started 11 of the Brewers' last 13 games and is slashing .264/.350/.382 with five home runs, 35 RBI, 35 runs scored, nine stolen bases and a 20:26 BB:K across 285 plate appearances this season.

Alvarez will start at third base and bat seventh in Monday's game against the Giants.

He'll pick up his sixth consecutive start at the hot corner after going 4-for-18 with a double, a walk and two runs since being called up from Triple-A Gwinnett on July 12. Though his production has been underwhelming thus far, Alvarez nonetheless appears on track to retain a regular spot in the Atlanta infield while Austin Riley (abdomen) is on the injured list.

Mauricio is out of the lineup for Monday's game against the Angels.

The switch-hitting Mauricio will head to the bench for a second straight matchup with a left-handed starter (Tyler Anderson), after the infielder was previously held out of the lineup in Sunday's 3-2 win over the Reds while southpaw Andrew Abbott toed the slab for Cincinnati. Luisangel Acuna will pick up another start and could end up settling into a loose platoon with Mauricio, who has gone 1-for-15 with six strikeouts versus lefties so far this season.
