McMahon went 1-for-3 with a three-run home run, a walk and an additional run scored in Tuesday's win over St. Louis.

The third baseman extended his hit streak to six games Tuesday with a three-run homer off Erick Fedde in the third inning. A popular trade candidate ahead of the deadline, McMahon is heating up at the right time, slashing .333/.417/.857 with two doubles, three homers and seven RBI during the streak. He's posted an OPS above .700 in every regular season since 2019 and is under contract through 2027, making him an appealing target for contenders who could net the Rockies an intriguing package in return.

Muncy (knee) took batting batting practice on the field Tuesday, Jack Harris of the Los Angeles Times reports.

Muncy resumed swinging a bat Friday, and he took another step toward his return from a left knee injury Tuesday. The veteran third baseman was given a six-week timeline when he was placed on the injured list July 3, and he appears to be in line to meet or beat that estimate. Dodgers manager Dave Roberts said Sunday that Muncy's return is "coming a lot quicker than we had hoped or had expected" and said the slugger could be back in "a couple weeks," per Fabian Ardaya of The Athletic.

Urias went 2-for-4 with a run scored in Tuesday's 6-3 loss to Cleveland.

Urias tallied his 16th multi-hit game of the season. With Baltimore's infield trio of Gunnar Henderson, Jackson Holliday and Jordan Westburg all healthy, Urias has been the odd man out lately when it comes to playing time. Urias has made just nine appearances in July, during which he's batting only .148 with two extra-base hits and zero RBI.

Shaw went 2-for-4 with an RBI and a run scored in Tuesday's 6-0 win over the Royals. He also stole a base.

Shaw has now collected hits in five straight games coming out of the All-Star break, and three of those have been multi-hit efforts. The rookie has been up and down this season, though he's managed to string together a few hot streaks here and there. Shaw has also been solid on the bases with 13 steals in 15 attempts. The young infielder may be susceptible to slumps at the plate, but his talent is evident.

Lee isn't in the lineup for Tuesday's game against the Dodgers.

After going 0-for-7 with a walk and a run scored in his first three games of the second half, Lee will take a seat Tuesday with Willi Castro set to start at the keystone.

The Athletics placed Muncy (hand) on the 10-day injured list Tuesday.

Muncy, who was hit by a pitch on the right hand Monday, appeared to have avoided a serious injury when X-rays came back negative, but he'll still need to spend some time on the shelf. The 22-year-old will be eligible to be rejoin the active roster in early August. Luis Urias and Gio Urshela are the likely candidates to man second base while Muncy is out.

Riley (abdomen) will not be activated from the 10-day injured list Tuesday and could have his return pushed back to Friday, Mark Bowman of MLB.com reports.

The expectation had been that Riley would return from the IL on Tuesday when first eligible, but Atlanta is all but out of playoff contention and has decided it would be wise to give the third baseman a little more time to recover from his right abdominal strain. Nacho Alvarez will continue to fill in at the hot corner until Riley is activated.

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.
