Hall (oblique) threw a bullpen session Tuesday, Jack Stern of BrewerFanatic.com reports.

He'll have another mound session later this week. Out since mid-August with a strained right oblique, Hall hopes to return before the conclusion of the regular season.

The Rangers optioned Curvelo to Triple-A Round Rock on Tuesday.

He's being sent out to accommodate the return of Danny Coulombe. Curvelo has posted a 5.50 ERA and 19:10 K:BB over 18 frames out of the Rangers' bullpen this season.

The Rangers activated Coulombe (shoulder) from the 15-day injured list Tuesday.

Coulombe has been shelved since late August with left shoulder fatigue but has been cleared to return to action following a brief rehab assignment. He'll play a key left-handed relief role in the Rangers' bullpen.

The Orioles optioned Wolfram to Triple-A Norfolk on Tuesday.

Wolfram has struck out 31 over 26 innings with the Orioles, but he's also posted a 4.85 ERA and 1.77 WHIP. He's clearing out to make room on the roster for waiver claim Jose Castillo.

Palencia (shoulder) joined the Cubs for their road trip in Pittsburgh and threw off a mound Monday for the first time since landing on the injured list Sept. 8, the Associated Press reports.

Prior to being deactivated after he was diagnosed with a left shoulder strain, Palencia had emerged as the Cubs' closer and converted 22 of 25 save chances while logging a 3.00 ERA and 1.18 WHIP over 51 innings on the season. The right-hander is without a definitive timeline for a return from the IL, but the fact that he's resumed mound work leaves the door open for him to be activated before the regular season comes to an end Sept. 28. In addition to completing another side session or two, Palencia will likely need to face hitters in live batting practice or in a brief minor-league rehab assignment before the Cubs add him back to their bullpen.

Gage (0-1) took the loss in Monday's 8-1 defeat to the Diamondbacks, allowing one earned run on one hit and one walk across one relief inning.

Gage entered the game in the fifth inning and retired three of the four batters he faced, walking one. However, he gave up a double to begin the sixth and was subsequently removed. The right-hander has allowed five runs in his last three appearances, giving up six hits and two walks while hitting one batter in 2.2 innings during that span. He has recorded a 3.97 ERA, 1.50 WHIP and 21:9 K:BB across 22.2 innings in 23 appearances with San Francisco this season.

Peguero allowed two earned runs on one hit and two walks across one-third of an inning in Monday's 8-1 loss to the Diamondbacks.

Peguero entered the game in the sixth inning with a runner on second. The right-hander then walked back-to-back batters before allowing a single and being replaced. Over 11 appearances this season, the 28-year-old owns a 1.84 ERA, 1.02 WHIP and 11:6 K:BB across 14.2 innings.

Hodge allowed a hit and two walks while retiring two batters in the ninth inning of Monday's win over the Pirates before getting lifted for Brad Keller, who recorded the final out of the game.

Hodge got the ninth inning staked to a 4-0 lead, so it wasn't a save opportunity, but he quickly made trouble for himself by loading the bases. The Cubs then turned to Keller for the final out, and he managed to earn his second save of the season by cleaning up Hodge's mess. Hodge continues to struggle with a 5.81 ERA and 1.52 WHIP across 31 innings this year, and Monday's poor effort won't help the righty earn any more high-leverage work in Chicago's bullpen.

Atlanta optioned Diaz to Triple-A Gwinnett on Tuesday.

Diaz has made three relief appearances after being claimed off waivers by Atlanta on Sept. 7, yielding four runs (three earned) with a 5:5 K:BB. The former Reds closer holds an 8.18 ERA over 18 relief outings in the big leagues this season.

Seymour struck out a batter and allowed one earned run on three hits over one inning of relief in Sunday's 10-2 loss to the Dodgers.

Seymour had started in each of his previous three appearances, but after he turned in an 8.68 ERA and 1.71 WHIP across 9.1 innings in those outings, he was moved to the bullpen. The Giants called on Seymour to mop up in the ninth inning of Sunday's blowout loss, and most of the 26-year-old righty's appearances for the remainder of the season are likely to come in lower-leverage spots.
