Halvorsen (elbow) has resumed throwing from 60 feet and is hoping to return from the injured list prior to the end of the season, MLB.com reports.

This marks Halvorsen's first notable progress since he was sidelined in early August with an elbow injury. He hopes to pitch in a game before the season is over, but Halvorsen is expected to be at full strength shortly after the campaign ends if he cannot return.

Fairbanks picked up the save Tuesday against the White Sox, throwing a perfect ninth inning. He did not record a strikekout.

Fairbanks snapped a streak of five consecutive outings allowing at least one hit. During that stretch, he surrendered four runs on nine hits, including three home runs, with eight strikeouts across five innings. Wednesday's save was Fairbanks' 25th of the campaign, tying his most saves in a season during his seven-year career. He has a 3.15 ERA in 54.1 innings this season.

Walker allowed a hit and a walk in a scoreless inning to earn the save in Tuesday's 5-3 win over the Diamondbacks.

Walker imploded versus the Cardinals on Saturday, and while he wasn't that sharp Tuesday, he was able to get the job done. He's converted five of six save chances over his last seven appearances, and he's been scored on in just two of 14 outings since the start of August. For the season, Walker has a 3.86 ERA, 1.18 WHIP and 55:15 K:BB through 56 innings, and he's converted 15 of 20 save opportunities.

Munoz secured the save Tuesday against the Cardinals, striking out one and allowing one hit in a scoreless ninth inning.

Munoz recorded his 34th save of the season in his third straight scoreless outing. The All-Star right-hander owns a 1.63 ERA, 1.05 WHIP and 71:25 K:BB through 55.1 innings on the campaign. Munoz is third in the major leagues in saves for the year, and he's established a strong grip on the Seattle closer role.

Pagan secured the save Tuesday against the Padres, striking out one in a clean ninth inning.

It was Pagan's first save of the month of September and his 27th of the year. The 34-year-old right-hander has been rather shaky of late -- he has a 5.02 ERA in 15 appearances since the start of August -- but he appears to still have the trust of manager Terry Francona as the team's closer. Through 60.2 innings, Pagan has a 3.26 ERA, 0.94 WHIP and 73:20 K:BB.

Jax will serve as the Rays' opening pitcher for Wednesday's game against the White Sox, Ryan Bass of FanDuel Sports Network Sun reports.

With Ryan Pepiot unavailable for his scheduled start Wednesday due to fatigue, the Rays will turn to Jax to lead off what's expected to be a bullpen game. The 30-year-old right-hander has given up eight earned runs in just 12 innings since being acquired from the Twins at the trade deadline and isn't expected to pitch past the first inning during what will be his second opening assignment in seven days.

Ferrer recorded one out to earn the save against Miami on Tuesday, allowing a hit without a walk or strikeout.

Ferrer came into a 7-4 game with a runner on second base. That runner would score, adding another run to Cole Henry's final line, but Ferrer would walk away with his eighth save of the year. Ferrer has now delivered 15.2 straight innings without giving up an earned run, lowering his ERA from 5.03 to 3.89 in the process. He's converted all eight of his save chances since stepping into the closer role for Washington.

Bowlan will serve as the Royals' opening pitcher for Wednesday's game against the Guardians, Anne Rogers of MLB.com reports.

The Royals are seemingly going to rely on their bullpen to get through Wednesday's contest, and they'll start by sending out Bowlan for the first handful of outs. The 28-year-old owns a 3.57 ERA and 1.13 WHIP through 35.1 innings on the season and has five appearances of at least two innings, so there's a chance he remains in Wednesday's contest past the first frame before getting the hook.

Bellozo was pulled from Tuesday's game against the Nationals with right triceps tightness, Kevin Barral of FishonFirst.com reports.

Bellozo gave up two hits and struck out a batter across two-plus innings out of the bullpen Tuesday before his triceps forced him out during the ninth. The severity of his injury remains unknown, though the Marlins will presumably stay away from using Bellozo in relief over the next couple of days.

The Padres optioned Jacob to Triple-A El Paso on Tuesday.

Michael King (knee) was activated from the 15-day injured list and is starting Tuesday, so Jacob was optioned to make room. Jacob made three appearances after being recalled Sept. 2, allowing one earned run on two hits with a 3:3 K:BB across 3.1 innings.
