The Reds optioned Moll to Triple-A Louisville on Tuesday, Charlie Goldsmith of Fox 19 Now Cincinnati reports.

The Reds have a bullpen game Tuesday against the Blue Jays and needed a reliever who can provide more length than Moll, who has covered just 18.1 frames in his 23 appearances this season. Reiver Sanmartin is taking Moll's spot on the roster.

The Reds selected Sanmartin's contract from Triple-A Louisville on Tuesday, Charlie Goldsmith of Fox 19 Now Cincinnati reports.

Sanmartin hasn't pitched in the majors since 2023 but has had a nice season at Louisville, collecting a 2.79 ERA and 44:17 K:BB over 58 innings. He could be asked to eat multiple innings during a bullpen game Tuesday versus the Blue Jays.

Barlow will serve as the Reds' opening pitcher in Tuesday's contest versus the Blue Jays, Gordon Wittenmyer of The Cincinnati Enquirer reports.

Nick Lodolo was scheduled to start but was scratched due to an illness, so the Reds will go with an impromptu bullpen game Tuesday. Barlow will likely pitch an inning or two before being followed by a slew of relievers.

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.
