Rivas (undisclosed) was activated from the 7-day injured list Friday.

Rivas missed all of June while dealing with an unspecified injury, but he made four rehab appearances in the Arizona Complex League in early July and has since returned to Triple-A Tacoma. He's 1-for-5 with a walk and three strikeouts in two games since his activation.

Chapman (abdomen) has been faring well in his rehab and could be activated in time for San Francisco's upcoming homestand, which begins Friday against the Angels, Evan Webeck of the California Post reports.

Webeck notes that Chapman made it through one of his more active rehab days yet Monday, and he felt good throughout the workout. Manager Tony Vitello stated that he believes Chapman could be activated from the 10-day injured list in time for Friday's series opener, though the team should have a better idea of his return date as the week progresses.

Loftin is out of the lineup for Monday's game against the Giants.

Loftin will move to the bench for the series opener after he went 1-for-12 at the dish while starting in all three of the Royals' games versus the Padres over the weekend. Josh Rojas will fill in for Loftin at third base and will bat eighth.

Muncy is out of the lineup for Monday's game against the Phillies.

With a tough lefty (Cristopher Sanchez) on the bump for the Phillies, the left-handed-hitting Muncy will hit the bench while the Dodgers make room in the infield for Miguel Rojas. Muncy had started in each of the Dodgers' previous five games, going 3-for-15 with a home run, a double, four walks, two runs and two RBI.

The Astros optioned Delgado to Triple-A Sugar Land on Monday, Brian McTaggart of MLB.com reports.

Delgado was recalled and started at second base in Sunday's loss to the Orioles, but he finds himself back in the minors a day later. He'll be used as a utility infielder at Sugar Land.

Piasentin has not played for the Florida Gulf Coast League Blue Jays since June 8 due to knee soreness, Geoff Pontes of Baseball America reports.

Pontes reports that Piasentin, who has not been officially placed on the injured list, could be back soon. The 6-foot-3 third baseman is hitting .188 with a .349 OBP, one home run and a 26.7 percent strikeout rate in 21 games as a 19-year-old in complex ball.

Riley will start at third base and bat cleanup in Monday's game versus the Padres.

Riley is coming off a big weekend series against the Rangers, having gone 6-for-12 with three home runs. As a result, he is up in the cleanup spot for Atlanta for the first time since May 18. Riley had batted seventh in each of his last four and 13 of his last 16 starts.

Arias is out of the lineup for Monday's game against the Twins.

The Guardians will go with Daniel Schneemann at third base while Arias retreats to the bench for the series opener. Arias had covered the hot corner in four of Cleveland's previous five games, going 5-for-15 with a walk, two stolen bases and two runs during that stretch.

Rengifo went 3-for-5 with a walk and three runs scored Sunday in a 19-2 rout of the Royals.

Rengifo was one of six Padres with multiple hits in the runaway win, recording his first three knocks since joining San Diego. The utility man hasn't gotten many opportunities since his contract was selected July 8 -- Sunday was his first start and just his second appearance since that date. Despite some past success in the majors that includes a pair of double-digit homer seasons and a 24-theft campaign, Rengifo isn't likely to make waves in fantasy unless he begins to receive more playing time.

Arenado went 1-for-4 with a two-run home run in Sunday's extra-inning win over the Cardinals.

Arenado's lone hit was a big one, as his two-run homer in the eighth inning tied the game at 7-7. The 35-year-old has put together a productive July, slashing .250/.321/.563 with four homers, 10 RBI and nine runs scored across 13 contests. Overall, Arenado is hitting .244/.318/.422 with 13 homers, 44 RBI and 46 runs scored across 93 games in his first season with the Diamondbacks.
