Atlanta activated Riley (personal) from the paternity list Thursday.

Because of a pair of rainouts, Riley missed just one game while spending the maximum three days away from the team on paternity leave. He'll be back in the lineup for Atlanta's series opener Thursday against the Mets.

Burger is out of the lineup for Thursday's game against the Orioles.

Burger will head to the bench after he saw his eight-game hitting streak come to an end with an 0-for-4, two-strikeout showing in Wednesday's 6-3 win. Emmanuel Rivera will spell Burger at third base in the series finale.

Marte went 1-for-5 with a double and two RBI in Wednesday's 9-4 win over Atlanta.

Marte joined the Reds' party with a two-run double in the fourth inning. The struggling third baseman, who is batting .181 since he completed his 80-game PED suspension, has hit safely in four straight games (4-for-17).

Suarez went 2-for-4 with a solo home run in Wednesday's 8-6 win over Kansas City.

Suarez's second-inning blast gave Arizona an early lead and was the first of four Diamondback home runs. He's doing his best to put a season-long slump behind him; Suarez entered the month of July with six home runs and has hit that many over the last 14 games. During that span, he's knocked in 17 runs with a .692 slugging percentage and 1.014 OPS.

Vientos went 1-for-4 with a solo home run and an additional RBI in Wednesday's 12-3 win over the Yankees.

Vientos knocked in the first and last runs during the Mets' eighth-inning rally, opening the inning with a solo shot before adding a sacrifice fly. The infielder is batting .294 (20-for-68) with three homers and 10 RBI over 18 contests in July as he continues to hold down a starting role at third base. For the year, he's slashing .290/.345/.545 with 13 homers, 35 RBI, 30 runs scored, 12 doubles and no stolen bases over 220 plate appearances.

Espinal will start at second base and bat eighth in the second game of Wednesday's doubleheader versus Atlanta.

Espinal has now picked up just two starts in the Reds' six games since the All-Star break. He saw an uptick in playing time to close out the second half while Jonathan India managed a knee contusion, but Espinal has shifted back into a utility role now that India has seemingly moved past the injury.

McMahon (finger) will start at third base and bat fourth in Wednesday's game versus the Red Sox.

He jammed a finger in Monday's game and didn't play Tuesday, but he's feeling well enough to give it a go in Wednesday's series finale. McMahon has reached base 11 times over his last five contests but will bring a 23-game homerless streak into action Wednesday.

Arenado went 1-for-3 with a solo home run in Tuesday's 2-1 win over the Pirates.

Arenado showed some veteran savvy, opening the scoring with his fifth-inning solo shot off Pirates wunderkind Paul Skenes. While Arenado is just 3-for-18 over five games since the All-Star break, two of those hits have landed over the fence. The third baseman is up to 10 long balls, 42 RBI, 40 runs scored, 14 doubles and one stolen base while slashing .265/.319/.387 through 95 contests.

McMahon (finger) isn't in the Rockies' lineup Tuesday against the Red Sox.

A jammed finger prevented McMahon from starting Monday's game, and he'll need at least another day to recover before returning to Colorado's starting nine. Aaron Schunk will pick up another start at third base and bat ninth Tuesday.

Rios signed a minor-league deal with the Reds on Tuesday, Charlie Goldsmith of The Cincinnati Enquirer reports.

Rios was designated for assignment Friday and elected free agency. However, after spending the weekend testing the open market, he'll return to the Reds organization on a minor-league pact. The 30-year-old slashed .236/.333/.483 in 204 plate appearances with Triple-A Louisville.
