The Mets optioned Waddell to Triple-A Syracuse on Tuesday, Michael Mayer of MetsmerizedOnline.com reports.

Waddell tossed 4.1 scoreless innings out of the bullpen in Sunday's loss to the Marlins but now finds himself back in the minors. The Mets have elected to replace him on the roster with a position player in Jared Young.

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

Indianapolis had previously shelved Harrington on Aug. 10 due to an unspecified injury, and though he was activated Thursday, he made it through just one inning during his start against Buffalo before landing back on the IL a day later. The Pirates haven't shed light on the nature of Harrington's latest setback, but given the timing of the injury, the right-hander could be hard-pressed to pitch again in 2025.

Atlanta designated Suero for assignment Tuesday.

The transaction frees up a spot on the 40-man roster for the addition of Hayden Harris. Suero has been knocked around for eight runs over 6.1 innings during his time with Atlanta this season.

Atlanta optioned Stratton to Triple-A Gwinnett on Tuesday.

Stratton was scored upon in each of his last two relief appearances and has earned a trip back to the minors. Hayden Harris is absorbing Stratton's spot on the roster and in the bullpen.

Atlanta selected Harris' contract from Triple-A Gwinnett on Tuesday.

Harris has had a dominant season in the minors between Double-A Columbus and Gwinnett, allowing just three runs with a 73:16 K:BB over 48 innings. The 26-year-old will be making his major-league debut when/if he gets into a game.

The Pirates recalled Sanders from Triple-A Indianapolis on Monday.

Sanders was one of two additions for the Pirates with the active roster expanding to 28 men in September, as utility player Nick Yorke also received the call from Triple-A. The right-handed reliever has previously made five appearances for Pittsburgh this season, giving up five earned runs on seven hits and four walks while striking out four across five innings.

Backhus allowed two runs on two hits over one-third of an inning in Monday's 7-5 extra-inning loss to Texas.

Backhus entered the top of the ninth inning to close out Arizona's 5-3 lead but couldn't convert on the opportunity. He wasn't charged with a blown save, but it felt like one. The Diamondbacks' closer spot has been in flux since losing Justin Martinez (elbow), A.J. Puk (elbow) and Kevin Ginkel (shoulder) to injury.

Duran notched a save against the Brewers on Monday with a perfect inning of work.

Duran needed just six pitches to retire Milwaukee in order in the ninth inning. The right-handed closer has successfully converted nine of 10 save opportunities since joining Philadelphia at the trade deadline, registering a 1.69 ERA, 0.94 WHIP and 13:0 K:BB over 10.2 frames spanning 13 appearances over that stretch. Duran's save Monday was his 25th of the campaign, and he's just two shy of the career-high mark he established with Minnesota in 2023.

Burgos suffered a right forearm contusion in Monday's 7-5 extra-inning loss to the Rangers, Alex Weiner of ArizonaSports.com reports.

Burgos was struck in the right arm by a 108.6 mph line drive off the bat of Alejandro Osuna with two outs in the top of the ninth inning, ultimately exiting the game as a result. The right-hander underwent X-rays, which came back negative, but he will undergo additional testing Tuesday.

Adam was diagnosed with a left quadriceps tendon rupture following Monday's 4-3 loss to the Orioles, Dennis Lin of The Athletic reports.

Adam went down with what appeared to be a significant left leg injury with one out in the top of the seventh inning. It is now understood to be a quad issue, and the right-hander will now be sidelined for the foreseeable future. Adam is likely done for the season, and in his absence, Adrian Morejon may be thrust into a more prominent role in the back end of San Diego's bullpen.
