The Phillies activated Ross (back) from the 15-day injured list Tuesday.

Ross has been sidelined since late July with back spasms but is ready to go following a brief rehab assignment. He'll fill a multi-inning relief role.

The Nationals optioned Brzykcy to Triple-A Rochester on Tuesday.

The right-hander reportedly had a chance to enter Washington's high-leverage mix after closer Kyle Finnegan was traded last week, but Brzykcy will instead be demoted after giving up six runs over one-third of an inning Sunday against the Brewers. The 26-year-old has a 9.00 ERA, 1.74 WHIP and 24:12 K:BB across 23 major-league innings this season.

The Nationals recalled Beeter from Triple-A Rochester on Tuesday.

The right-hander was acquired from the Yankees last week and is now receiving his first look with the Nationals. Beeter allowed six earned runs in two appearances with the Yankees this year, but he fared better at Triple-A Scranton/Wilkes-Barre with a 3.54 ERA across 20.1 innings, though he still had an ugly 1.64 WHIP.

The Reds recalled Zulueta from Triple-A Louisville on Tuesday.

Zulueta will provide a fresh relief arm after the Reds' bullpen had to cover 7.1 innings in Monday's win over the Cubs. The right-hander has made two appearances for Cincinnati this season, allowing one run across 2.1 frames.

Cardinals manager Oliver Marmol said Tuesday that Thompson (lat) has suffered another setback, Matt Pauley of KMOX Sports reports.

Marmol didn't offer any additional specifics on Thompson's status, but it's yet another setback with a left lat strain that's kept the hurler out all season. At this stage of the season, the odds of Thompson making it back to pitch this year appear long. The bigger question might be whether he needs surgery, and that is unclear.

The Brewers sent Miller (forearm) to Triple-A Nashville on Tuesday to begin a rehab assignment.

The Brewers acquired Miller from the Diamondbacks at the trade deadline knowing he would still need some time to work his way back from a strained forearm. Miller has been out for nearly a month, so he'll probably need at least a couple rehab appearances before joining the Brewers bullpen. The righty delivered a 1.98 ERA, 0.96 WHIP and 40:11 K:BB while notching 10 saves over 36.1 frames for Arizona before landing on the injured list July 7.

The Pirates are expected to call up Sanders from Triple-A Indianapolis on Tuesday, Alex Stumpf of MLB.com reports.

Sanders made a mechanical adjustment while at Double-A Altoona and has taken off, compiling a 1.91 ERA and 51:20 K:BB over 42.1 frames between Altoona and Indianapolis. The 28-year-old reliever will be making his major-league debut when/if he gets into a game.

Seymour picked up a hold in Monday's 5-4 loss to the Pirates, allowing two earned runs on one home run and one walk while striking out two across two innings.

Seymour retired the side in order in the sixth inning, but he gave up a walk and a subsequent home run in the seventh. Still, the right-hander protected the lead and earned his first hold in five big-league appearances. During that span, he has allowed six earned runs -- including five homers -- on 13 hits and four walks while striking out 11 over 11 innings.

Assad (oblique) struck out two and allowed two runs (one earned) on four hits and one walk across 3.2 innings in his rehab start Wednesday with Triple-A Iowa.

After tossing three scoreless frames in his first rehab outing July 24 in the rookie-level Arizona Complex League, Assad jumped up a few levels for his second outing. The right-hander got stretched out to 53 pitches (32 strikes) in the start and is expected to build upon that workload when he makes his next rehab appearance with Iowa on Wednesday, per MLB.com reports. Though Assad still appears more likely than not to work in long relief or stick around in Iowa's rotation once he's activated from the 60-day injured list, he could be needed to make starts with the big club if he ends up beating Jameson Taillon (calf) and Michael Soroka (shoulder) back from the IL.

Brasier (0-1) allowed a run on two hits while retiring two batters in relief to take the loss in Monday's 3-2 defeat to the Reds.

After Michael Soroka covered two innings before departing with a shoulder injury and Ben Brown worked the next four frames, Brasier came on in the seventh with the game tied 2-2. The veteran reliever allowed an RBI single to TJ Friedl that broke the tie and ultimately saddled him with his first loss of the season. Brasier still has a solid 3.27 ERA and 1.05 WHIP this year, and he should retain a key role in a Chicago bullpen that added Taylor Rogers and Andrew Kittredge before the trade deadline.
