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.

Bregman is not at 100 percent when running the bases, but he's still expected to continue handling a near-everyday role, Chris Cotillo of MassLive.com reports.

Bregman's abilities on the bases appeared to be compromised during Monday's extra-inning loss to the Phillies, when he was unable to score from first base on a Roman Anthony double down the right field line. He eventually scored two pitches later, so his tentative baserunning didn't end up costing the Red Sox. As Cotillo reported when Bregman returned to action prior to the All-Star break, manager Alex Cora said that the veteran third baseman would not be running hard in certain situations as the Red Sox aim to preserve his health. Since Bregman was activated from the injured list July 11, the Red Sox have managed his workload by giving him a day off following two consecutive starts. He'll start Tuesday's game in Philadelphia but is likely to rest in Wednesday's series finale.

Jung went 2-for-2 with a solo home run, two additional runs and a walk in a 7-2 win against the Athletics on Monday.

Jung was summoned from Triple-A Round Rock on Monday and started at third base while batting eighth upon his return. The 27-year-old excelled in his first game back with the big club, reaching base in all three of his plate appearances and belting a solo shot in the third inning to start the scoring. Jung has struggled with a .242/.290/.381 slash line this season, but he's shown some pop with nine home runs through 300 plate appearances.

Lewis went 3-for-4 with a double and one stolen base in Monday's 5-2 loss to the Dodgers.

Lewis is 5-for-8 over the last two games, and he also picked up his first steal of the season Monday. This may be the spark the third baseman needs to get things going again, though he's been fairly steady by batting .294 (15-for-51) since returning from a hamstring injury at the start of July. He's up to a .233/.293/.360 slash line with four home runs, 15 RBI and 16 runs scored across 45 contests this year.

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.

Williamson went 2-for-3 with a stolen base in Monday's 6-0 loss to the Brewers.

Williamson had gone 0-for-8 over his previous three games, and this was just his second multi-hit effort in July. The rookie third baseman continues to earn his playing time through steady defense rather than big contributions on offense. For the season, he's slashing .259/.293/.319 with one home run, 19 RBI, 35 runs scored and three steals across 76 contests, giving him minimal upside as a contact hitter with little pop at the bottom of the order.

Vargas went 1-for-3 with a two-run homer, two walks and an additional run scored in Monday's 8-3 win versus the Rays.

Vargas drew his fifth consecutive start at first base and homered for the second consecutive contest with a two-run long ball off Tampa Bay starter Shane Baz in the fifth. Before these back-to-back games with home runs, Vargas was mired in a 26-game homerless drought during which he batted .158 (15-for-95), so perhaps he is turning a corner. Across 400 total plate appearances, the 25-year-old has a .711 OPS with 12 homers, four steals, 51 runs scored and 40 RBI.

X-rays on Muncy's right hand returned negative following Monday's game against the Rangers, Martin Gallegos of MLB.com reports. He exited the matchup after being struck by a pitch in the fifth inning.

Muncy is likely dealing with a bruised hand considering further scans returned negative. He'll be deemed day-to-day until the club has a chance to re-evaluate the 22-year-old. Gio Urshela entered the game in Muncy's place Monday and could be in line for more playing time if Muncy is forced to sit for a few days, though Luis Urias would also be a candidate for at-bats.

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.
