McMahon went 2-for-4 with a three-run home run, an additional RBI and an additional run scored in Tuesday's 8-5 loss against the Padres.

McMahon went yard for a second consecutive contest, tagging reliever Steven Wilson for a three-run shot in the seventh that scored Jurickson Profar and Ezequiel Tovar. The third baseman has posted multiple hits in five of his last seven games and has logged an extra-base hit in four consecutive contests. Across his last seven appearances, McMahon is batting 11-for-28 (.393) with three homers, 10 RBI and six runs scored.

Candelario went 4-for-5 with a double and two runs scored in Tuesday's 20-9 win over the Reds.

Candelario, who started at first base and batted sixth in his first game since getting traded to Chicago on Monday, wasted no time making an impact. He's currently fourth in the majors with 31 doubles and should fit in nicely with the Cubs, which is the team he made his MLB debut with back in 2016 before getting shipped to Detroit the following season. It appears that Candelario will primarily play first for Chicago.

The Pirates reinstated Hayes (back) from the 10-day injured list Tuesday.

Hayes won't be in the Pirates' lineup Tuesday against the Tigers, but he was deemed healthy enough to rejoin Bucs' active roster after going 1-for-9 with a run scored during his three-game rehab assignment in Triple-A. Hayes has been on the IL since July 7 and will most likely return to action Wednesday.

Castro was traded from the Pirates to the Phillies on Tuesday in exchange for Bailey Falter, Alex Coffey of The Philadelphia Inquirer reports.

Best known for crushing left-handed pitching (career .277/.341/.559 slash line in 223 plate appearances), Castro had been at Triple-A Indianapolis for the past couple weeks after hitting .228/.317/.355 overall for the Pirates this season, contributing to a minus-0.3 fWAR. Castro provides the Phillies with some infield versatility, as he can play second base, third base and shortstop.

The Cardinals acquired Prieto, left-hander Drew Rom and right-hander Zack Showalter from the Orioles on Tuesday in exchange for right-hander Jack Flaherty.

Prieto looks like he has a big-league future, but he was sufficiently blocked in the Orioles organization. A 24-year-old Cuban infielder, Prieto is hitting .317/.365/.471 with two home runs, two steals and an 8.7 percent strikeout rate in 27 games at Triple-A Norfolk. He'll likely report to the Cardinals' top affiliate in Memphis but could be in the mix for a late-season call-up to the big leagues.

Cubs manager David Ross said Tuesday that Candelario will get regular starts at first base, Mike McGraw of the Chicago Daily Herald reports.

Acquired from the Nationals on Monday in exchange for a pair of minor-leaguers, Candelario is making his Cubs debut at first base Tuesday night against the Reds. Nick Madrigal is starting at third base and Christopher Morel is serving as the designated hitter. This new defensive formation will allow Cody Bellinger to see more action in center field as Chicago looks to make a late run at the NL Central title.

Hayes (back) won't be in the starting lineup Tuesday against the Tigers, but he could be activated from the 10-day injured list Wednesday or Thursday, Kevin Gorman of TribLive.com reports.

For those in weekly lineup leagues, Hayes could play most of the week, but he won't be in the lineup for the first of six Pirates games this week. In the meantime, Jared Triolo figures to continue working at the hot corner until Hayes returns to the lineup.

The Marlins acquired Burger from the White Sox on Tuesday in exchange for Jake Eder, Craig Mish of the Miami Herald reports.

Burger will provide a power boost to a Marlins team that currently ranks 28th in the majors in home runs. He's popped 25 homers and his .527 SLG would rank as a top-10 mark if he had enough plate appearances to qualify. The 27-year-old has been rather one-dimensional as evidenced by his .214 average and .279 OBP; nevertheless, Burger figures to take over the starting job at third base from Jean Segura.

Kieboom (oblique) is set to begin a rehab assignment Tuesday with High-A Wilmington, Mark Zuckerman of MASNSports.com reports.

Kieboom has been on the minor-league injured list since June 20 because of an oblique strain, but he's rounding back into good health and could potentially get a look in Washington down the stretch. The 25-year-old former top prospect hasn't appeared in a major-league game since 2021, battling various injuries along the way, but with Jeimer Candelario traded to the Cubs, Kieboom could get a look at third base for the Nationals down the stretch if he can stay healthy.

Rivera started at third base and went 1-for-3 with a walk and a run scored in Monday's 4-3 extra-innings win over San Francisco.

Rivera's 10th-inning single gave the Diamondbacks a brief lead before the Giants scored in the bottom of the frame. It was his sixth straight game with hit; he's 8-for-20 during the streak. A series of moves over the last few days impacts third base going forward. After placing Evan Longoria (back) on the injured list Saturday, Arizona traded infielder Josh Rojas to Seattle then acquired infielder Jace Peterson from Athletics. Peterson is essentially a Rojas replacement -- a left-handed bat that plays second and third base -- and could emerge as a platoon mate of Rivera.
