Spiers is likely to enter the Reds' rotation in place of the injured Julian Aguiar (shoulder), Charlie Goldsmith of The Cincinnati Enquirer reports.

Aguiar had been slated to make his final start of the season Wednesday in Cleveland, but that assignment should fall to Spiers, who will be on seven days' rest after throwing 46 pitches over three relief innings last week against Atlanta. It will be Spiers' first start since Aug. 20, when he allowed 10 runs (nine earned) across 4.1 frames in Toronto.

Walker pitched a perfect inning and earned the save in Monday's 6-3 win over the Diamondbacks.

Walker has rebounded with a pair of saves since he took a walk-off loss versus the Orioles last Thursday. The right-hander is up to 10 saves this year, which is impressive considering he took over the closing job in mid-August and the Giants haven't exactly been a dominant team. He's added 22 holds with a 1.94 ERA, 0.84 WHIP and 99:17 K:BB across 79 innings in his second major-league campaign.

Kilian (0-1) took the loss Monday, allowing six runs (five earned) on eight hits and four walks over 5.2 innings against the Phillies. He struck out three.

Kilian was called up earlier in the day and then tossed 5.2 innings in a bulk-relief role. It was his first major-league appearance of 2024 after having appeared in six big-league contests over the previous two seasons. Kilian has now allowed 28 earned runs across 22.1 career big-league innings.

Banks will serve as the Phillies' opening pitcher for Tuesday's game against the Cubs, Matt Gelb of The Athletic reports.

Banks will be asked to work an inning or so before turning the ball over to a bulk reliever. Gelb notes that Kolby Allard or Taijuan Walker will likely be used in long relief Tuesday.

The Cubs claimed Paredes off waivers from the Brewers on Monday, Sahadev Sharma of The Athletic reports.

Paredes will remain in the division after the Brewers booted him from their 40-man roster after he posted a 1.74 ERA and 14:10 K:BB over 20.2 innings in the big leagues. The 28-year-old does not have any minor-league options remaining, so he will be added to the Cubs' 28-man active roster.

The Cubs recalled Hollowell from Triple-A Iowa on Monday, Sahadev Sharma of The Athletic reports.

Hollowell was claimed off waivers from the Diamondbacks in August and will now get his first stint in the majors with the Cubs. The 26-year-old holds a 4.94 ERA and 45:21 K:BB across 31 innings this season at the Triple-A level.

The Cubs optioned Wingenter to Triple-A Iowa on Monday, Sahadev Sharma of The Athletic reports.

Wingenter has made five relief appearances for the Cubs this season, allowing two runs with a 3:2 K:BB over six frames. He had pitched both of the last two days, so the Cubs are replacing him with a fresh arm in Gavin Hollowell, who was recalled from Triple-A in a corresponding move.

The Cubs recalled Kilian from Triple-A Iowa on Monday, Maddie Lee of the Chicago Sun-Times reports.

Right-hander Nate Pearson is serving as the Cubs' opening pitcher for Monday's game in Philadelphia, but he's likely to cover only an inning or two before turning the contest over to the bullpen. Kilian will be available out of the bullpen and may end up taking on a bulk-relief role for the Cubs, as his final start with Iowa came six days earlier. Kilian made three appearances (one start) for the Cubs in 2023 but has pitched exclusively in the minors in 2024, turning in a 3.22 ERA, 1.15 WHIP and 38:14 K:BB over 44.2 innings with Iowa.

The Cubs placed Lopez on the 15-day injured list Monday with a right groin strain, Sahadev Sharma of The Athletic reports.

Lopez returned from the same injury just last week, so he evidently must have suffered a setback. The injury ends what was a nice bounce-back season for Lopez, who collected a 2.89 ERA and 50:19 K:BB over 53 innings covering 52 appearances for the Mets and Cubs. He'll be a free agent this offseason.

Martinez (5-6) was charged with a blown save and the loss after allowing one run on three hits and no walks over one-third of an inning Sunday against the Brewers.

Arizona held an 8-0 lead after two and a half frames Sunday, but Martinez and the rest of the bullpen were unable to maintain the advantage. The right-hander entered with two outs in the eighth inning and the Diamondbacks leading 9-7, and he proceeded to give up three runs (two inherited runners) on two singles, a double and a wild pitch. A.J. Puk picked up a save Friday in Milwaukee, which combined with Martinez's save Sept. 4 account for Arizona's only saves so far this month. Martinez should be the favorite for saves in the final week of the regular season, but the lefty Puk is also in the mix.
