Bivens allowed one earned run on three hits and one walk across 1.1 innings in Tuesday's 5-1 loss to the Padres.

Bivens entered the game with one out and the bases loaded in the fourth. He walked one batter, forcing in a run, but prevented the Padres from doing further damage. The right-hander ran into trouble in the fifth, giving up two singles, a double and a run before being pulled with two outs and a runner on. The 31-year-old has appeared in 10 games since the All-Star break, posting a 6.89 ERA, 2.11 WHIP and 11:6 K:BB across 15.2 innings during that span.

Lawrence (elbow) walked one and struck out three in a scoreless frame in his first rehab appearance with Single-A Bradenton on Tuesday.

Lawrence is finally game-ready again after missing nearly four months with right elbow inflammation. He'll likely require a handful of rehab outings before rejoining the Pirates bullpen. Lawrence had permitted just one run with a 15:6 K:BB over 11.1 frames before getting injured.

Mayza (lat) allowed two hits and struck out one in two-thirds of an inning in his first rehab appearance with Single-A Bradenton on Tuesday.

Mayza has been shelved since late April with a left lat strain but is gearing up for a return to the Pittsburgh bullpen. Given the amount of time he's missed, he'll likely require a few more rehab appearances before being activated from the 60-day injured list. The veteran lefty had yielded only three runs with an 8:1 K:BB over 9.1 innings for Pittsburgh before getting hurt.

O'Brien earned the save in a 7-4 win over the Marlins on Tuesday. He did not allow a hit but walked two and also struck out two in a scoreless inning.

O'Brien was called upon for the save chance after JoJo Romero pitched against the heart of the Miami order in the eighth. Things did not begin well for O'Brien, who walked consecutive batters to open up the inning, but he rebounded with back-to-back strikeouts before getting a groundout to end the game. O'Brien now has two saves to Romero's three since the departure of Ryan Helsley at the deadline. O'Brien has found his footing this season, posting a 1.56 ERA, 1.18 WHIP and 34:17 K:BB in 34.2 innings.

Gibaut (shoulder) has been scheduled to undergo arthroscopic surgery, MLB.com reports.

Gibaut was pulled off a rehab assignment earlier this month when his arm didn't respond well following an outing. No date for the surgery was provided, nor was an expected timeline for his recovery.

Saalfrank struck out one in a perfect inning to earn the save in Tuesday's 6-5 win over the Guardians.

Saalfrank took a blown save in Colorado on Saturday, allowing two runs in two-thirds of an inning. He bounced back with a sharp outing Tuesday, needing just nine pitchers to retire the Cleveland trio of Jose Ramirez, Kyle Manzardo and Carlos Santana. It's interesting that Saalfrank got the nod for this save when fellow left-hander Jalen Beeks had pitched just once over the previous four days. Arizona's bullpen has turned into a full-blown committee throughout the year between injuries and ineffectiveness. Saalfrank has been a breath of fresh air, pitching to a 1.72 ERA, 1.09 WHIP and 10:5 K:BB over 15.2 innings while picking up two saves and one hold. It's unclear if this outing is a signal that the 28-year-old will be competing for more save chances down the stretch, but he has taken care of business in lower-leverage spots to earn a larger role.

Santillan struck out two over a perfect inning to earn the save in Tuesday's 6-4 win over the Angels.

Emilio Pagan pitched Saturday and Sunday, but he's been held out of save opportunities Monday and Tuesday. Santillan got the job done on 12 pitches Tuesday after Scott Barlow converted the save Monday. Santillan has had mixed results in August, allowing three runs over 7.2 innings with a 9:6 K:BB, though he's also picked up five holds and a blown save. He remains in the high-leverage mix, and if the Reds' bullpen becomes a committee, that would likely increase his save share. For the season, Santillan has a 2.79 ERA, 1.09 WHIP and 57:22 K:BB with four saves and 27 holds across 58 innings.

Kittredge tossed a scoreless ninth inning to record the save in the second game of Tuesday's doubleheader against the Brewers.

Regular closer Daniel Palencia secured the save in the first game Tuesday, but the Cubs didn't use him for the nightcap, instead turning to Kittredge to protect a 4-1 lead. The veteran righty breezed through the top of the ninth inning on 10 pitches, giving him his second save in the last three days. Palencia is still the top option out of the Chicago bullpen, but it appears that Kittredge has earned some trust in late-game situations when needed.

Iglesias picked up the save in Tuesday's 11-10 win over the White Sox, throwing a clean ninth inning with no strikeouts.

That's now 12 consecutive scoreless innings for Iglesias, who has successfully converted each of his nine save chances during that span. The veteran right-hander had briefly lost his grip on the closer job at one point amid a dismal start to the campaign -- he had a 6.75 ERA through June 5 -- but he's been well back on track for over two months now. Over his last 28.2 innings, Iglesias boasts a 1.57 ERA, 0.63 WHIP and 32:4 K:BB.

Palencia recorded his 17th save of the season in the first game of Tuesday's doubleheader against the Brewers, giving up a hit and a walk while striking out one in a scoreless ninth inning.

The right-hander hit triple digits on the radar gun with nine of his 17 pitches (11 strikes), but it was a 90.5 mph slider that got William Contreras to ground into a game-ending double play. Palencia has had a bumpy beginning to August, allowing runs in three of his six appearances while blowing one of four save chances, but his job as the Cubs' closer is in no jeopardy. On the season, Palencia sports a 1.81 ERA, 0.94 WHIP and 47:12 K:BB through 44.2 innings.
