Rivera (shoulder) is absent from the lineup Tuesday versus the Mets.

Rivera injured his left shoulder while trying to catch a ball near the stands in Monday's series opener at New York, though it's not believed to be anything serious. Jace Peterson will get the start at third base for the Diamondbacks on Tuesday. Geraldo Perdomo is covering shortstop.

Marte (nose) remains out of the lineup Tuesday at Detroit.

Marte suffered a broken nose Saturday when he was struck in the face by a ball during pregame warmups, but he cleared the concussion protocol and apparently won't require a stay on the injured list. Nick Senzel is covering third base and batting second for the Reds on Tuesday.

Rivera exited Monday's win over the Mets with a shoulder injury, MLB.com reports.

Rivera, who started at third base, made an awkward attempt to catch a foul ball near the stands while running into the tarp. He stayed in the game for another inning before being removed. Arizona manager Torey Lovullo believes Rivera is fine and described him as day-to-day. He was replaced at third base by Jace Peterson.

Muncy went 1-for-5 with a solo home run in Monday's 11-8 loss to the Padres.

Muncy has homered three times in his last four games while adding six RBI in that span. The infielder continues to display solid power with 35 long balls and a .493 slugging percentage through 120 contests this season. He's added 97 RBI, 84 runs scored and a stolen base despite batting a meager .208, though his on-base percentage is a respectable .331.

Machado went 2-for-5 with two home runs and three RBI in Monday's 11-8 win over the Dodgers.

Machado has hit safely in seven of nine games in September, going 12-for-38 (.316) with four multi-hit efforts. The third baseman popped a solo shot in the fourth inning and a two-run blast in the sixth to help the Padres pull off a comeback Monday. For the season, he's up to 28 homers, 84 RBI, 72 runs scored, three stolen bases and a .252/.315/.460 slash line over 128 contests. Machado continues to serve as San Diego's designated hitter while playing through tennis elbow.

The Brewers selected Donaldson's contract from Triple-A Nashville on Monday. He'll start at third base and bat fifth in the Brewers' series opener with the Marlins.

Milwaukee transferred reliever J.C. Mejia (shoulder) from the 15-day injured list to the 60-day IL to clear room on the 40-man roster for Donaldson, who went 3-for-17 with two home runs and five walks in five games for Nashville after inking a minor-league deal with the Brewers on Aug. 31. Prior to catching on with Milwaukee, Donaldson hit .142 with 10 home runs in 120 plate appearances for the Yankees before landing on the injured list July 16 with a right calf strain and then getting cut loose in late August when he completed a minor-league rehab assignment. Donaldson will likely be ticketed for a short-side platoon role at either designated hitter or third base initially, but the 37-year-old could earn more opportunities against right-handed pitching if he fares well in his initial action with Milwaukee.

Kieboom is out of the lineup for Monday's game against the Pirates, Andrew Golden of The Washington Post reports.

Kieboom will take a seat for the second time in three days while the Nationals make room at third base for Ildemaro Vargas. With Kieboom turning in a modest .610 OPS in 15 games since his call-up from Triple-A Rochester in late August and with the switch-hitting Vargas offering a potential strong-side platoon option, Kieboom could see his opportunities against right-handed pitching take a hit as the season winds down.

Rosario went 1-for-4 with a solo home run in Sunday's loss to Houston.

Rosario accounted for one of two San Diego runs in the contest with his 409-foot solo shot in the seventh inning. It was the first major-league homer for the 24-year-old, who went deep five times over 43 games with Triple-A El Paso before being called up last Friday. Rosario homered 22 times and stole 21 bases across 124 contests in Triple-A last season. He could get a decent look down the stretch with the Padres fading further out of contention for a playoff spot.

Peterson is out of the lineup for Monday's game against the Mets.

Since being acquired from Oakland on July 31, Peterson has mostly served as a strong-side platoon option at third base, but he'll likely have to settle for more of a utility role moving forward. With both second baseman Ketel Marte (knee) and shortstop Jordan Lawlar (hand) back in the lineup Monday after one-game absences, Peterson will retreat to the bench after he manned the keystone Sunday. Geraldo Perdomo has seemingly supplanted Peterson as the Diamondbacks' preferred option at third base.

Sosa is out of the lineup for the first game of Monday's doubleheader with Atlanta, Scott Lauber of The Philadelphia Inquirer reports.

Sosa went 4-for-18 with a home run, a stolen base, two RBI and three runs while making five starts in the Phillies' past seven games, but he'll be back on the bench for the first game of Monday's twin bill. Despite the uptick in playing time of late, Sosa still looks to be viewed as a utility man and doesn't have a direct path to an everyday spot in the lineup.
