O'Brien picked up the save in Tuesday's 3-0 win against the Reds, striking out one in a perfect ninth inning.

With JoJo Romero handling the eighth against the bottom of Cincy's order, O'Brien was entrusted with a three-run lead in the ninth and made quick work of the Reds' 2-3-4 hitters, needing just nine pitches to lock down his fifth save of the year. It marked the right-hander's third save in his last five appearances. The 30-year-old sports a 2.08 ERA, 1.15 WHIP and 41:20 K:BB across 43.1 innings this season.

Akin allowed a hit and struck out two in a scoreless inning to earn a save against the White Sox on Tuesday.

Akin gave up a one-out single to Chase Meidroth before striking out the last two batters he faced to close out the 8-7 win. It was Akin's sixth save in nine chances since the start of August. During that span, he's produced a 3.15 ERA while also adding four holds. For the year, Akin owns a 3.20 ERA with a 56:31 K:BB and six saves through 59 innings.

Hoffman recorded two outs, both by strikeout, to earn a save against the Rays on Tuesday. He gave up a walk and a hit but was not charged with a run.

Hoffman entered a 6-4 game with a runner on third and one out in the ninth inning. The inherited runner scored on an RBI single by Brandon Lowe before Hoffman walked Junior Caminero, but the right-hander rallied to strike out the final two batters he faced. It was Hoffman's 31st save in 38 chances and his first conversion since Sept. 2. He's given up one run over his last 7.2 innings and now owns a 4.64 ERA with an 83:23 K:BB through 64 frames.

Taylor (groin) will be available out of the bullpen for Tuesday's game against the Orioles, Jack Ankony of SI.com reports.

Taylor hasn't pitched since suffering a groin strain during Wednesday's game versus the Rays. After coming away from his bullpen session Monday without any issues, the White Sox have given him the green light to return to game action. The 23-year-old hasn't exactly been effective in his MLB debut, accumulating a 5.68 ERA and 1.52 WHIP across 31.2 innings.

The Giants optioned Winn to Triple-A Sacramento on Tuesday, Shayna Rubin of the San Francisco Chronicle reports.

Winn gave up five earned runs across eight innings during his latest stint in the majors. He'll now return to Triple-A to make room for Trevor McDonald, who will provide San Francisco with a fresh bullpen arm.

Manager Pat Murphy said Tuesday that he expects Mears (back) to return from the injured list Wednesday, Jack Stern of BrewerFanatic.com reports.

Lingering back tightness sent Mears to the injured list in early September, but he now seems to be ready to return to Milwaukee's bullpen without embarking on a rehab assignment. The 28-year-old righty owns a career-best 3.42 ERA and 0.91 WHIP through 52.2 innings on the year, and he'll likely be used in high-leverage situations with Trevor Megill (elbow) is still on the shelf, although Abner Uribe remains the top option for save chances.

Megill (elbow) will be reevaluated Tuesday after feeling soreness following a live batting practice session, Jack Stern of BrewerFanatic.com reports.

Megill felt soreness in his pitching elbow after a bullpen session last week as well. Despite that setback, he was cleared to faced hitters, but given the lingering issues, his return doesn't appear imminent. Abner Uribe has recorded three saves since Megill's last appearance in late August, with Jared Koenig and Aaron Ashby also picking up one each.

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.
