Peterson is absent from the lineup Tuesday versus the Rockies.

Emmanuel Rivera will cover third base and Evan Longoria will take a turn as the Diamondbacks' designated hitter with Colorado throwing left-hander Kyle Freeland. Peterson has batted .167 with a .407 OPS in 55 plate appearances against lefties this year.

Muncy (shoulder) is out of the lineup Tuesday at Miami.

Muncy was lifted from Sunday's series finale against Atlanta after tweaking his left shoulder on a swing, though there doesn't seem to be much concern that it will be a long-term injury. Enrique Hernandez is playing third base for the Dodgers on Tuesday as Will Smith takes a turn in the DH role and Austin Barnes handles the catching duties.

Vientos (foot) is batting fifth as the Mets' designated hitter Tuesday against the Nationals, Anthony DiComo of MLB.com reports.

Vientos hasn't seen game action since Saturday while dealing with a foot injury, but he'll rejoin the lineup for Tuesday's contest in Washington. The 23-year-old is 5-for-10 with two solo homers in his past three games but still has a disappointing .586 OPS in 144 plate appearances this season.

Newman (oblique) will begin a rehab assignment Tuesday with Triple-A Louisville.

On the shelf since Aug. 19 because of a left oblique strain, Newman looks poised to return to the Reds' active roster around the end of this week. The 30-year-old infielder was slashing .253/.311/.364 with three homers and eight steals through 74 games for Cincinnati prior to the injury.

Hayes went 2-for-4 with a solo home run in Monday's 4-2 victory versus the Brewers.

Hayes broke a 2-2 tie with his fifth-inning solo shot, and that held up as Milwaukee didn't score again in the contest. The third baseman has gone deep four times over his past 11 games, a span in which he's slashing .348/.412/.696 with eight RBI and nine runs. Hayes is up to a career-high 12 homers on the campaign, five more than he hit over 560 plate appearances last season.

Muncy left Sunday's game against Atlanta due to a shoulder injury after striking out in the fifth inning, but manager Dave Roberts doesn't believe it will be an IL situation, Michael J. Duarte of NBC LA reports.

Roberts characterized the shoulder issue as a "tweak" and indicated that Muncy should be fine. Muncy had gone 1-for-3 prior to his departure, breaking a two-game hitless stretch with a fourth-inning single. Should the slugger need to miss any games, the Dodgers could start Chris Taylor, Michael Busch or Enrique Hernandez at third base in his place.

Candelario went 1-for-4 with a solo home run and two runs scored in Sunday's 15-7 victory over the Reds.

Candelario chipped in to Chicago's rout, launching his 21st home run of the season in the ninth inning. The infielder has been solid for the Cubs since rejoining the team before the trade deadline. Across 30 games, Candelario has an .831 OPS to go along with five home runs, 14 RBI and 17 runs scored.

Longoria started at designated hitter and went 1-for-3 in Sunday's 8-5 loss to the Orioles.

Longoria was a late addition to the lineup after Tommy Pham (finger) was scratched. It's unclear if Pham's swollen pinky finger will keep him sidelined for Monday's series opener against Colorado. Longoria is 4-for-21 with three walks, one RBI and eight strikeouts over eight games since returning from the injured list.

Machado went 3-for-4 with a solo homer and two runs scored in Sunday's win over the Giants.

Machado's solo shot in the fourth inning was his 26th long ball of the year. However, in his previous 30 appearances since the start of August, he went deep just five times while posting a .645 OPS. His disappointing season line now sits at .249/.313/.454 with 45 extra-base hits and 79 RBI through 527 plate appearances.

Vientos (foot) is out of the lineup for Sunday's game against the Mariners.

Vientos will take a seat for the series finale after he went 2-for-3 with a solo home run and a walk before exiting Saturday's 8-7 loss with a sore right foot. The Mets will have Labor Day off, so Vientos will get two days to move past the foot injury before the team opens its two-game set in Washington on Tuesday.
