The Pirates activated Shugart (knee) from the 15-day injured list Monday.

Left knee inflammation had sidelined Shugart since early July, but he's been cleared to return after making three rehab appearances. The righty reliever holds a 3.69 ERA and 1.15 WHIP over 39 innings this season, but a 22:15 K:BB is less than ideal.

The Pirates optioned Moreta to Triple-A Indianapolis on Monday.

Moreta has permitted two runs with a 7:1 K:BB over 4.2 innings during his time with the Pirates this season. He's clearing out to make room on the active roster for the return of Chase Shugart (knee).

The Diamondbacks claimed Varland (undisclosed) off waivers from the White Sox on Monday and optioned him to Triple-A Reno.

Varland hasn't pitched since June 28 due to an undisclosed injury but will give the Diamondbacks some experienced relief depth once he's available to pitch. The righty has put up a 4.82 ERA and 47:24 K:BB over 46.2 innings in parts of two major-league seasons.

The Diamondbacks recalled Morillo from Triple-A Reno on Monday.

Morillo has made 31 appearances out of the Diamondbacks bullpen this season, posting a 4.94 ERA and 28:16 K:BB over 27.1 innings. The 26-year-old could work his way into high-leverage appearances as part of an unsettled bullpen, although he's unlikely to be in the mix for save chances right away.

The Reds returned Gibaut (shoulder) from his rehab assignment Monday, Charlie Goldsmith of Fox 19 Now Cincinnati reports.

Gibaut remains on the 15-day injured list, so he must have encountered a setback while on a rehab assignment with Triple-A Louisville, where he allowed four runs in two-thirds of an inning in his most recent appearance Wednesday. The righty reliever has been out since late June with a right shoulder impingement.

Diaz (5-2) took the loss Sunday against the Brewers, giving up one run on one hit in one-third of an inning.

The Mets headed into the eighth inning with a 6-5 lead, but Ryan Helsley blew the save and needed to be replaced by Diaz to get the final out of the frame. The team's closer had his own struggles in the ninth however, as Isaac Collins took him deep to walk it off. It was the first earned run Diaz had been tagged with since April 21, but both his losses on the season have come in three August appearances, as he allowed the phantom runner to score in an extra-inning loss to the Giants on Aug. 1. Despite those recent setbacks, the 31-year-old right-hander has a stellar 1.60 ERA, 0.93 WHIP and 67:17 K:BB through 45 innings in 2025, converting 23 of 25 save chances.

Triple-A Indianapolis placed Harrington on its 7-day injured list Sunday due to an undisclosed injury.

After being demoted Aug. 2, Harrington rejoined the Indianapolis rotation Friday and apparently sustained an injury during that start. The right-hander possesses a spot on the Pirates' 40-man roster, but his injury coupled with his poor numbers at the Triple-A level this season (5.40 ERA, 1.33 WHIP in 95 innings) could hinder his chances of getting another look in the big-league rotation in 2025.

The Pirates will activate Shugart (knee) from the 15-day injured list before Monday's game in Milwaukee, Alex Stumpf of MLB.com reports.

Shugart has been shelved since early July with left knee inflammation but is ready to go after making three rehab appearances. He will likely fill a middle-relief role.

The Pirates will option Moreta to Triple-A Indianapolis prior to Monday's game in Milwaukee, Alex Stumpf of MLB.com reports.

He'll give up his spot in the bullpen and on the 26-man active roster to Chase Shugart (knee), who will be reinstated from the 15-day injured list. Moreta has pitched well during his five appearances with the Pirates this season, allowing two runs with a 7:1 K:BB over 4.2 innings.

The Cardinals are considering using Leahy as part of piggyback starts down the stretch with Andre Pallante and/or Matthew Liberatore, Derrick Goold of the St. Louis Post-Dispatch reports.

The Cardinals already have plans for Leahy to prepare this offseason to enter spring training as a starting pitcher, and the righty could get a jump-start on that preparation if the team opts to employ him in a piggyback role during the final two months of this season. Manager Oliver Marmol said there are currently no plans for piggyback starts, but it's being discussed as the club seeks to keep the workloads of Pallante and Liberatore in check. Leahy has been used exclusively as a reliever so far at the major-league level, but he'll often pitch multiple innings at a time and has past experience as a starter in the minors.
