McDonald allowed one run on six hits and a walk while striking out three over six-plus innings in a no-decision Sunday versus the Dodgers.

McDonald went pitch-for-pitch with Emmet Sheehan over the first six innings. In the seventh, McDonald put three straight batters on base, leading to the lone run on his line, before Spencer Bivens relieved him and put out the fire. McDonald has given up three runs while posting a 4:2 K:BB across eight innings over his two major-league outings this season. If he did enough Sunday to earn another turn through the rotation, that would likely come in a home matchup versus the Rockies in the final series of the season.

Spence (3-6) took the loss Sunday against the Pirates, allowing seven runs (six earned) on nine hits and two walks over 3.1 innings. He struck out one.

Spence struggled out of the gate Sunday, allowing a pair of two-out runs in the opening inning before the Pirates added on with a two-run homer in the second. It's the first start and second appearance for Spence since he was recalled from Triple-A earlier this month. Overall, the right-hander sports a 4.96 ERA with a 1.41 WHIP and 65 strikeouts across 81.2 innings this year.

Manager Pat Murphy said Sunday that the best case scenario for Megill (elbow) is to return for Milwaukee's regular-season finale Sept. 28 against Cincinnati, Adam McCalvy of MLB.com reports.

The best-case timeline, according to Murphy, would mean Megill would throw a bullpen Tuesday and live batting practice Friday. The timeline could be adjusted based on how the right-hander recovers from the throwing sessions, but that would mean he wouldn't return until the postseason. The Brewers are tracking toward a top-two seed in the NL, which would allow them to bypass the wild-card round and give Megill extra time to get healthy.

The Tigers selected Rainey's contract from Triple-A Toledo on Sunday, Evan Petzold of the Detroit Free Press reports.

Rainey began the season with the Pirates, accumulating an ugly 10.57 ERA and 1.70 WHIP over 7.2 innings spanning 11 appearances. He was released in early July and subsequently signed a minor-league deal with Detroit. Since joining the organization, Rainey has been effective with Toledo, posting a 2.52 ERA, 1.12 WHIP and 35:14 K:BB across 25 innings. He'll likely fill a low-leverage spot in the Tigers bullpen over the final week of the campaign. Charlie Morton was designated for assignment Sunday to make room for Rainey on the 28-man active roster and 40-man roster.

Pomeranz (2-2) allowed a run on two hits across an inning of work to take the loss Saturday against the Reds. He struck out two.

The southpaw entered a 2-2 game in the fifth inning after Chicago starter Javier Assad covered four innings, and Pomeranz allowed a solo home run to Spencer Steer. This was the first run allowed by the veteran reliever over his last seven appearances, and he still has a sparkling 2.30 ERA for the season to go along with a 10.0 K/9. Pomeranz should stick in a key relief role for the Cubs as they head into the playoffs.

Poulin struck out one in a perfect 11th inning Saturday to record his first career save in a 5-3 win over the Mets. He struck out one.

After Daylen Lile broke open a 3-3 tie in the top of the 11th with an inside-the-park homer, Poulin got the call in the bottom of the frame to face the Mets' 9-1-2 hitters, which included Francisco Lindor and Juan Soto. The rookie left-hander didn't flinch, firing seven of 12 pitches for strikes and getting Soto on a called strike three to end it. Jose Ferrer had worked the eighth and ninth just to get the game to extras, and Poulin isn't likely to get more closing chances this season, but through his first 22.2 MLB innings he's delivered a 2.78 ERA, 1.37 WHIP and 23:11 K:BB with two wins and five holds in addition to Saturday's save.

Clarke allowed no hits and a walk with no strikeouts over a scoreless inning Saturday against the Blue Jays to record his fifth hold of the season.

The 32-year-old was trusted with the eighth inning of a one-run game Saturday and came through, issuing only a harmless two-out walk before handing the ball off for Carlos Estevez to close. Clarke hasn't been a fixture in high-leverage spots this year, but he's been excellent in the second half, compiling a 1.98 ERA and 0.77 WHIP over 26 outings and 27.1 innings since the All-Star break.

Basso threw a perfect inning with no strikeouts in Saturday's loss to the Pirates.

Basso worked a clean eighth inning Saturday in a game where the Athletics' offense couldn't get going. The left-hander was called up Aug. 27 and has been effective since, tossing nine straight scoreless appearances. It's a small sample, but the 27-year-old's early results are encouraging, especially considering he was primarily used as a starter before this year.

Dreyer struck out one in a perfect inning to earn the save in Saturday's 7-5 win over the Giants.

Tanner Scott had a 23-pitch appearance Friday and was presumably unavailable for Saturday's game. The Dodgers had to dig deep in this game, with Alex Vesia also not pitching and Kirby Yates being deployed in the seventh inning, leading to Dreyer getting a rare chance to close a game out. He's up to four saves this season and has added 10 holds over 64 appearances. He's also pitched to a 2.80 ERA, 1.03 WHIP and 72:22 K:BB through 74 innings, and he's allowed just two runs with an 11:1 K:BB over eight innings in September.

Palencia (shoulder) began a rehab assignment with Triple-A Iowa on Saturday and allowed one unearned run on two hits while striking out two batters in two-thirds of an inning.

Iowa's season will come to an end Sunday, so Palencia may need to face hitters in a simulated game or two to prove his right shoulder strain is no longer a concern before the Cubs bring him back from the injured list. Prior to suffering the injury and landing on the shelf Sept. 8, Palencia led the Cubs with 22 saves. Brad Keller and Andrew Kittredge have been sharing the closer's role in Palencia's absence.
