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.

Arizona optioned Morillo to Triple-A Reno following Sunday's 5-1 win over the Angels.

Morillo went unused Sunday, but he was roughed up in his relief appearance in Saturday's 10-5 loss, giving up four runs on five hits while striking out one over one inning. Arizona will likely wait until later in the week before announcing a corresponding roster move.

The Marlins announced July 7 that Tinoco (forearm) is continuing to make progress with his throwing program and could soon be cleared to throw bullpen sessions, MLB.com reports.

Tinoco was able to resume playing catch just over a week after he was placed on the injured list June 6 due to a right forearm strain, but the Marlins have been bringing the right-hander along slowly in his recovery. As a one- or two-inning reliever, Tinoco won't require an extended rehab assignment, but since he has yet to get back on a mound, he shouldn't be expected to return from the IL until late July at the soonest.

Lord has a 2.79 ERA, 1.16 WHIP and 35:14 K:BB in 38.2 innings over 29 relief appearances this season.

The rookie right-hander made six starts earlier in the year with less impressive results, but since shifting to the bullpen Lord has found his groove. He's been even more effective since the beginning of June, delivering a 2.19 ERA, 0.81 WHIP and 18:6 K:BB over his last 24.2 innings while recording six of his seven holds on the season. He doesn't have the strikeout upside typical of high-leverage arms, but Lord could find himself in the closer picture for the Nationals if Kyle Finnegan gets shipped out at the trade deadline.

Rutledge coughed up four runs on four hits, including two home runs, over just one-third of an inning in Sunday's loss to the Brewers.

His lone out did come via strikeout, but it was still a rough way for the 26-year-old righty to end the first half. Rutledge boasted an ERA of 2.08 back on May 6 and looked like a potential high-leverage option for the Nationals' bullpen, but since then things have gone completely off the rails for the 2019 first-round pick. On the season, Rutledge carries a 6.92 ERA, 1.61 WHIP and 36:16 K:BB through 40.1 innings, and he's served up an ugly 12 homers.
