The Rockies optioned Bird to Triple-A Albuquerque on Monday.

The transaction frees a roster spot for the return of Antonio Senzatela (elbow), who is back from the 60-day injured list to make his season debut Monday against the Diamondbacks. Bird holds a 4.95 ERA and ugly 28:25 K:BB over 36.1 frames with the big club in 2024.

Holmes will start Tuesday's game against the Reds in Cincinnati, David O'Brien of The Athletic reports.

Atlanta will bring Holmes back from the bullpen to fill the rotation spot vacated by Reynaldo Lopez (shoulder), who was placed on the 15-day injured list last Wednesday. Holmes has previously made four starts for Atlanta, but he's worked exclusively in relief for the past month and hasn't covered more than two innings or 33 pitches in any of his last eight appearances. With that in mind, Holmes will likely be on a restricted pitch count Tuesday and could struggle to reach the five innings he would need to qualify for a win.

Rodriguez (elbow) threw 30-pitch bullpen sessions at Oracle Park on Thursday and Sunday, MLB.com reports.

After being placed on the 15-day injured list Aug. 15 with a right elbow flexor strain, Rodriguez was shut down for two weeks before he was cleared to begin a throwing program Sept. 3. He looks to be building up his pitch count through side sessions and should soon be ready to face hitters before likely heading out on a brief minor-league rehab assignment. Rodriguez could make it back from the IL during the final week of the regular season.

Moreta (elbow) is throwing from 60 feet, MLB.com reports.

Moreta underwent Tommy John surgery in mid-March, with this marking his first activity since. He is projected to return in June of 2025.

Kittredge (4-5) allowed one run on two hits and a walk while striking out one over two-thirds of an inning to take the loss Sunday versus the Blue Jays.

This outing brought an end to Kittredge's 11.2-inning scoreless streak, a span in which he logged three wins and three holds. He's mostly been able to limit any struggles this season to two or three outings at a time, which has helped him remain a steady setup man for a Cardinals team that is often in tight games. Kittredge is now at a 2.97 ERA, 1.16 WHIP, 61:20 K:BB, one save and 33 holds over 63.2 innings.

Iglesias (5-2) took the loss Sunday against the Dodgers, allowing five runs on four hits and a walk while striking out one in just two-thirds of an inning.

Iglesias was working in a tie game and retired two of the first three hitters he faced with Will Smith hitting a triple. Atlanta opted to intentionally walk Shohei Ohtani to get to Mookie Betts, who put the Dodgers ahead with a base hit. Iglesias was unable to get the final out, as Freddie Freeman singled home another two runs and Teoscar Hernandez mashed a two-run homer. It was a truly shocking performance from Iglesias who had not allowed an earned run since June 16 and hadn't allowed more than two hits since April 24. Iglesias is still having a career year with a 1.87 ERA, 0.72 WHIP and 64:12 K:BB in 62.2 innings and needs four more saves to set a new career high.

Kopech (6-8) got the win over Atlanta on Sunday, allowing one hit and one walk while striking out two in a scoreless inning.

Kopech pitched the bottom of the eighth with the game tied 2-2 and kept things tied despite allowing two baserunners. The Dodgers would then go on to score seven runs in the top of the ninth to put Kopech in line for the win. The 28-year-old righty has pitched scoreless outings in seven of his last eight appearances but has also allowed at least one baserunner in five of those. For the year, Kopech sports a 3.59 ERA, 1.16 WHIP and 83:32 K:BB in 62.2 innings.

Doval (5-3) allowed two runs (one earned) on two hits and struck out one over one inning, taking the extra-inning loss versus the Padres on Sunday.

Doval worked the 10th inning but couldn't keep the Padres in check. He had appeared to stabilize his performance after returning from a stint at Triple-A Sacramento in August, but he's faded again in September, allowing nine runs (eight earned) over 6.2 innings this month. Doval is now at a 5.17 ERA, 1.65 WHIP and 71:36 K:BB with 22 saves and three holds over 54 innings, but he could be out of the high-leverage picture by the end of the campaign given his current trend.

Roupp allowed two hits and two walks while striking out four over five scoreless innings in a no-decision versus the Padres on Sunday.

Roupp has allowed two runs on seven hits and two walks over 10 innings across two starts since he joined the Giants' rotation. He was efficient Sunday, throwing 74 pitches (51 strikes) in this outing. He may continue to stretch out over the remainder of the campaign, which gives him a chance to be in the conversation for a rotation spot next year. Overall, Roupp has pitched to a 3.02 ERA, 1.25 WHIP and 40:21 K:BB through 41.2 innings over 21 appearances this year.

Morejon allowed an unearned run over one inning without giving up a hit or a walk, earning the save in Sunday's 4-3 extra-inning win over the Giants.

Regular closer Robert Suarez worked the ninth inning and took a blown save, but the Padres were able to gain the lead in the 10th. Morejon then closed things out, earning his second career save, both of which have come over his last 15 appearances. In that span, he's allowed seven runs (six earned) across 13.2 innings. The southpaw is at a 3.00 ERA, 1.27 WHIP and 67:20 K:BB with 10 holds through 60 innings this year, emerging as an option for high-leverage work in a talented Padres bullpen.
