Riley went 2-for-5 with a solo home run, a double and an additional run scored in Sunday's 9-8 loss to Colorado.

Riley gave Atlanta a hot start with his first-inning homer and came around to score again on a Matt Olson double in the seventh. Riley is 7-for-23 (.304) with three homers and eight RBI over his last five contests. For the season, he's posted a .264/.330/.475 slash line with 18 homers, 55 RBI, 60 runs scored, 26 doubles and no stolen bases over 103 games. His power is still behind where it's been over the previous three years, but it appears he's turning things around.

The Nationals are expected to call up Chaparro from Triple-A Rochester ahead of Tuesday's game against the Angels, Andrew Golden of The Washington Post reports.

Washington acquired Chaparro at the trade deadline in a deal that sent relief pitcher Dylan Floro to the Diamondbacks. The 25-year-old infielder will get his first taste of the big leagues after he combined to hit .328 with 23 home runs, 85 RBI, 76 runs and three stolen bases over 105 games with Triple-A Reno and Triple-A Rochester this season. With Jose Tena sustaining a thumb injury Sunday that could force him to the injured list, Chaparro could end up replacing him as the Nationals' primary option at third base in the short term.

President of baseball operations Andrew Friedman said Sunday in an interview with Jim Bowden of MLB Network Radio on SiriusXM that he expects Muncy (oblique) to be reinstated from the 60-day injured list at some point during the Dodgers' next homestand, which begins Aug. 19.

Out since mid-May due to a significant right oblique strain, Muncy finally reached the last stage of his recovery program by kicking off a rehab assignment with Triple-A Oklahoma City on Saturday. He started at third base and played six innings in the field while going 1-for-2 with a double, a walk and an RBI. Though Muncy is back in the lineup Sunday at designated hitter for Oklahoma City, he'll presumably get in a few more games at third base and potentially even at first base during the upcoming week as he works to regain his timing at the plate. Assuming he avoids any setbacks with his oblique during the rehab assignment, Muncy should step back into an everyday role in the infield right away once the Dodgers activate him.

Vientos was scratched from the lineup for Sunday's game against the Mariners due to left ankle soreness, Anthony DiComo of MLB.com reports.

The ankle issue has apparently been bothering Vientos since late July and cost him a start Aug. 5 against the Cardinals, but he had been part of the lineup in four of the Mets' subsequent five contests. Assuming Vientos isn't dealing with any sort of major setback with the ankle, he should have a good chance at returning to the lineup for Tuesday's series opener versus the Athletics following Monday's team off day.

Vientos (undisclosed) was scratched from Sunday's lineup against the Mariners, Anthony DiComo of MLB.com reports.

Vientos was originally set to start at third base and bat eighth Sunday, but he's been scratched for an undisclosed reason. More information on his status will likely come in the near future, but in the meantime, Jose Iglesias will slide over to the hot corner while Ben Gamel enters the lineup in right field after some lineup shuffling.

Tena (thumb) had X-rays come back negative after leaving Sunday's game against the Angels and is dealing with a fingernail issue, Spencer Nusbaum of The Washington Post reports.

The 23-year-old made his second straight start at third base Sunday but exited during the fourth inning when he was struck in the right hand by a hard grounder. Tena has avoided a serious injury and should be considered day-to-day.

Muncy (oblique) went 1-for-2 with a double, a walk and an RBI in a rehab game with Triple-A Oklahoma City on Saturday.

Muncy performed well in his first game action since May 15. The third baseman is working his way back from an oblique injury and subsequent rehab that progressed slowly and at times was described as "stagnant." He'll need at least a handful more games in the minors to knock off some rust before the Dodgers are ready to bring him back from the 60-day injured list.

Candelario is not in the lineup for Sunday's game against the Brewers.

Candelario will sit after going 0-for-3 on Saturday to end a seven-game hit streak. Jonathan India will serve as the designated hitter while Santiago Espinal starts at second base.

Rivera is out of the lineup for Sunday's game against the Padres.

Rivera's absence is his fourth in Miami's past six games, with both of his starts during that stretch coming against left-handed pitchers. Jake Burger is receiving more run at third base and Jesus Sanchez at designated hitter, which has opened up right field for Derek Hill, though the latter two have swapped those positions Sunday.

Tena was removed in the fourth inning of Sunday's game against the Angels due to an apparent right thumb injury, Mark Zuckerman of MASNSports.com reports. He went hitless in his lone at-bat before departing.

Making a second straight start at third base after he went 2-for-4 with two RBI in his Nationals debut Saturday, Tena's day was cut short when he took a hard grounder off his throwing hand. The play went down as an error, and Tena was immediately lifted from the game in favor of Ildemaro Vargas while his thumb was bleeding profusely. The Nationals should have an update on Tena's condition later Sunday.
