The Marlins placed Cabrera on the 15-day injured list Monday due to a right elbow sprain.

The team hasn't revealed when Cabrera's elbow began bothering him, but he was knocked around in his last start, allowing six runs (five earned) over four innings in a win over the Mets on Saturday. The right-hander will be evaluated further before a timeline for his return is laid out. Given the nature of the injury, a return before the end of the season seems unlikely, and surgery could be a possibility. If his season is indeed over, Cabrera will finish with a 3.57 ERA and 140:42 K:BB over 128.2 innings covering 24 starts.

The Nationals selected Alvarez's contract from Triple-A Rochester on Monday.

Alvarez is set to make his major-league debut Monday with a start at home against the Marlins, taking the rotation spot of the injured MacKenzie Gore (shoulder). The left-handed Alvarez held a 4.10 ERA and 114:52 K:BB over 123 innings covering 25 starts for Rochester this season. He should receive multiple turns in the rotation while Gore is shelved.

Atlanta manager Brian Snitker said Aug. 14 that Lopez (shoulder) is unlikely to return from the 60-day injured list before the end of the season, MLB.com reports.

Snitker didn't specifically note that Lopez has experienced a setback in his recovery from the arthroscopic right shoulder surgery that he underwent in April. However, with Atlanta well removed from playoff contention heading into the final month of the season, Lopez won't be rushed along in his rehab program. Lopez resumed playing catch about a month ago and could continue throwing in September with the aim of having something close to a normal offseason. The right-hander is under club control through 2027 and should be in the running for a rotation spot next spring.

Weathers (lat) struck out six and allowed two earned runs on four hits and two walks over 2.2 innings in his rehab start with Triple-A Jacksonville on Saturday.

Taking the hill for the first time since June 7, Weathers fell just short of reaching his target of three innings, but he was still able to toss 60 pitches while generating 11 swinging strikes. Per MLB.com, Weathers is expected to make one additional start in the minors before slotting back into the Miami rotation.

Gordon didn't factor into the decision Sunday against the Cubs, allowing two runs on five hits and one walk across six innings. He struck out nine.

Gordon started August with a pair of ugly outings, allowing 17 runs and 23 hits in 7.1 innings. He's rebounded with four straight starts yielding three or fewer runs, including three consecutive quality starts. During that four-game stretch, Gordon has a 2.74 ERA and a 19:6 K:BB across 23 innings. His nine Ks marked a career high. Gordon is tentatively scheduled to face the Padres in his next start.

Boyd didn't factor into the decision Sunday against Colorado, allowing four runs on six hits and one walk with five strikeouts across six innings.

Boyd surrendered at least four runs for a third consecutive start, though he didn't allow a home run and walked fewer than three batters -- both things he wasn't able to do in the first two outings of that stretch. The left-hander has taken three losses in his last five starts, posting a 5.65 ERA and a 24:8 K:BB across 28.2 innings. He's tentatively scheduled to face the Nationals his next time out.

Luzardo allowed two hits and one walk while striking out seven over 6.2 scoreless innings in a no-decision versus Atlanta on Sunday.

Luzardo alternated between good and mediocre in August, but he was able to finish the month on a high note. Philadelphia couldn't maintain a 1-0 lead after Luzardo's exit, costing him the chance to earn his fourth win of the month. He gave up 12 runs over 34.2 innings while posting a 42:8 K:BB, turning things around in a big way after a much more shaky July. He's now at a 4.05 ERA, 1.28 WHIP and 182:52 K:BB through 155.2 innings over 28 starts this season. The left-hander is lined up to make his next start on the road in Miami.

Waldrep allowed one run on four hits and four walks while striking out nine over 5.2 innings in a no-decision versus Philadelphia on Sunday.

Waldrep has yet to give up more than one run in any of his six outings in the majors this season. While he walked a season-high four batters Sunday, his nine strikeouts were also a new high-water mark. The lone run against him came on a Brandon Marsh solo shot in the fourth inning. Through 35.2 innings, the rookie right-hander has a sharp 1.01 ERA, 1.01 WHIP and 33:11 K:BB. He'll look to keep his early success going at home versus Seattle in his next start.

Mazur is listed as the Marlins' probable starting pitcher for Tuesday's game in Washington, Kevin Barral of FishonFirst.com reports.

Mazur will draw a second turn through the rotation after he took a no-decision against the Mets on Thursday following his promotion from Triple-A Jacksonville. In that start, Mazur struck out two batters while allowing two earned runs on four hits and one walk. The upcoming start against the Nationals represents a more favorable matchup than the one with the Mets, but Mazur's lack of a track record of success in the majors coupled with his so-so numbers for Jacksonville this season (4.36 ERA, 1.30 WHIP and 100:30 K:BB in 107.1 innings) make him difficult to rely upon as a streaming option.

Woodruff (5-2) yielded eight runs (five earned) on 10 hits and two walks over 4.1 innings Sunday, striking out three and taking a loss against Toronto.

Woodruff struggled early Sunday and never recovered. The Blue Jays posted three unearned runs in the first inning, and Woodruff would later cough up five more runs, all earned. He set a new career high with eight total runs allowed. After posting a 2.47 ERA in his first eight starts of the year, Woodruff has given up 10 earned runs over 10 frames in his last two outings. The recent struggles have ballooned his ERA to 3.69 with a 66:14 K:BB through 53.2 innings this season. Woodruff is projected to start in Pittsburgh next weekend.
