Richards had a locker set up for him in Arizona's clubhouse Thursday, Alex Weiner of Arizona Sports reports.

It looks like the Diamondbacks will make a few roster moves Friday, including the addition of Richards. The club inked him to a minor-league deal last month after he opted out of a contract with the Royals, who had designated him for assignment. The 32-year-old right-hander will slot into the bullpen, which has been hit hard by injuries.

Thompson (shoulder) has begun a throwing program, Alex Weiner of Arizona Sports reports.

Thompson landed on the 15-day injured list with a scapular strain earlier this month. No timeline has been established for the return of the side-arming righty, who is needed in an Arizona bullpen that's been hammered by injuries.

Atlanta designated Chavez for assignment Thursday, David O'Brien of The Athletic reports.

Chavez has pitched primarily with Triple-A Gwinnett this season, though he was called up to the majors in early July He's made four appearances in the big leagues this year and has given up eight earned runs with an 8:5 K:BB over eight innings. The 41-year-old will now go through the waiver process and will be able to elect free agency if he goes unclaimed.

Dunning was traded from Texas to Atlanta in exchange for Jose Ruiz and cash Thursday, David O'Brien of The Athletic reports.

Dunning has spent the majority of his season at Triple-A Round Rock and has appeared exclusively as a reliever in his five big-league appearances. Atlanta's immediate plans for him are unclear, but the team has a significant need at starting pitcher with both Spencer Schwellenbach (elbow) and Chris Sale (elbow) sidelined. Dunning posted a 5.02 ERA and 1.31 WHIP across 71.2 innings as a starter during the 2024 regular season.

Miller (forearm) began a throwing program Thursday, Alex Weiner of ArizonaSports.com reports.

Miller sought a second opinion on his flexor tendon and UCL just before the All-Star break and apparently received good news. It's unclear how quickly he'll return, but this is still good progress in his recovery.

The Marlins transferred Tinoco (forearm) to the 60-day injured list Wednesday.

A right forearm strain sent Tinoco to the injured list in early June. The 30-year-old reliever has been throwing since mid-June and is nearing a return to mound work, though his move to the 60-day IL will ensure he remains out until at least Aug. 5. His 40-man roster spot will be handed to Michael Petersen, who was acquired in a trade with Atlanta on Wednesday.

Atlanta traded Petersen to the Marlins on Wednesday in exchange for cash, Christina De Nicola of MLB.com reports.

Petersen has bounced between Triple-A and MLB this season, giving up three runs in 6.2 innings during his time in the majors. Now changing organizations for the second time this season, he'll report to Triple-A Jacksonville to begin his tenure with the Marlins and take Jesus Tinoco's (forearm) place on the 40-man roster.

Treinen (forearm) pitched one inning Tuesday, allowing one run on one hit and striking out one batter, in a minor-league rehab outing with the Dodgers' rookie-level Arizona Complex League affiliate.

Treinen's first two rehab appearances came with Triple-A Oklahoma City, but he moved to the ACL team for Tuesday's outing because Los Angeles' other minor-league affiliates are out of action during the MLB All-Star break. The righty reliever served up a solo homer to Guardians prospect Dauri Fernandez but retired the other three batters he faced. Treinen has completed exactly one frame in each of his three rehab outings to date, giving up a combined two runs (one earned) on one hit with a 4:1 K:BB. He'll likely be back with the Dodgers at or shortly after the start of the second half of the big-league campaign.

The Brewers reinstated Ashby (personal) from the paternity list Monday.

Ashby will rejoin the Brewers to begin the second half after he missed the final three games before the All-Star break to observe the birth of his child. Through 13 appearances out of the Milwaukee bullpen this season, Ashby has compiled a 1.66 ERA, 1.06 WHIP and 26:7 K:BB in 21.2 innings while collecting one win and one save.

Walker is slated to make his next start Saturday against the Angels in Philadelphia, Matt Gelb of The Athletic reports.

After the Phillies optioned Mick Abel to Triple-A Lehigh Valley on July 4, Walker stepped in last week to fill the vacant rotation spot. Though he had made each of his previous nine appearances out of the bullpen, Walker came through with a strong showing July 8 in San Francisco, limiting the Giants to one run on two hits and two walks over four innings. Walker will likely have a longer leash during Saturday's contest, and he should be able to maintain a spot in the rotation until Aaron Nola (ankle/rib) is ready to return from the 60-day injured list around early or mid-August.
