Colorado transferred Darnell (hip) to the 60-day IL on Sunday.

The Rockies placed Darnell on the 15-day IL on Friday due to left hip inflammation, an injury that interim manager Warren Schaeffer acknowledged that the reliever had been dealing with "for a while," per MLB.com. While the Rockies haven't revealed that Darnell is dealing with anything more significant than swelling in the hip, the club evidently determined that the right-hander wasn't on track to return before the end of the season. Darnell will close his rookie campaign with a 3.86 ERA, 1.46 WHIP and 5:7 K:BB in 11.2 innings out of the Colorado bullpen.

The Rockies optioned Gilbreath to Triple-A Albuquerque on Sunday.

Gilbreath's stay with the big club lasted just two days, with the reliever making his lone appearance in Friday's 9-0 loss to Pittsburgh. He'll cede his spot on the 26-man active roster to right-hander McCade Brown, who was called up from Double-A Hartford to start Sunday's series finale versus the Pirates.

Atlanta placed Bummer on the 15-day injured list Sunday due to left shoulder inflammation.

The left-hander threw 1.1 scoreless innings Saturday against the Mets, which is presumably when he suffered the injury since that was his first appearance in nearly a week. Bummer will be eligible to be reinstated Sept. 8, though it's unclear if he's expected to be healthy by that point.

Atlanta recalled Stratton from Triple-A Gwinnett on Sunday.

The veteran right-hander was optioned to Gwinnett on Tuesday but will quickly return to Atlanta with Aaron Bummer (shoulder) landing on the injured list. Stratton has given up seven earned runs over 8.2 innings in the majors this year and should fill a low-leverage relief role.

Atlanta recalled Suero from Triple-A Gwinnett on Sunday.

The right-hander was optioned to Gwinnett in late July and will make his return to Atlanta a month later. Suero has surrendered six earned runs over five frames in the majors this year but has a 1.39 ERA in 42 relief appearances at Triple-A.

Thompson (shoulder) is scheduled to pitch for Triple-A Reno on Tuesday, MLB.com reports.

This is expected to be Thompson's final step before activation. The right-hander could immediately be added to Arizona's unsettled closer mix once he rejoins the roster.

Duran recorded his 23rd save of the season in Saturday's 6-4 win over the Nationals, giving up two hits in a scoreless ninth inning. He struck out one.

One night after blowing his first save as a Phillie, Duran was back on the mound, and the Nats nearly got to him again as back-to-back one-out hits put runners on the corners. The right-hander buckled down and struck out James Wood before getting CJ Abrams to fly out to end the game. Over nine appearances with his new club, Duran has delivered a 1.17 ERA, 0.78 WHIP and 9:0 K:BB in 7.2 innings while converting seven of eight save chances.

Mlodzinski improved to 3-7 and struck out five without allowing a baserunner across two scoreless innings of relief in Saturday's 5-1 win over the Rockies.

Mlodzinski had made a four-inning start in his last appearance Sunday against the Cubs, but he's since shifted back to the bullpen after the Pirates recalled Johan Oviedo from Triple-A Indianapolis and added him to the rotation earlier this week. The right-hander entered Saturday's game in the fifth inning after starter Mike Burrows was pulled in an apparent attempt to limit his workload. Mlodzinski was excellent in his two innings, generating 14 called or swinging strikes on 35 total pitches. He has allowed only three earned runs across six appearances and 14.2 innings since the start of August, while also maintaining an 18:3 K:BB.

Beeks served as the opener in Saturday's win over the Reds, striking out one in a perfect first inning.

The left-hander tossed 16 pitches to retire the side in order before handing the ball off to Nabil Crismatt, who worked the bulk of the innings. Beeks lowered his ERA to 3.99 with the outing and has now allowed just two runs across his last 11 appearances (11.2 innings).

Morejon struck out two over 1.1 perfect innings to earn the save in Saturday's 5-1 win over the Dodgers.

Morejon got the last out in the top of the eighth inning and remained in the game for the ninth after the Padres padded their lead. Both Robert Suarez and Mason Miller pitched Thursday and Friday, so Morejon likely would have been in contention for a more conventional save opportunity anyway. He's on a 10-inning scoreless streak with a 10:2 K:BB in that span. For the season, Morejon has maintained a stellar 1.81 ERA, 0.80 WHIP and 60:12 K:BB over 59.2 innings while adding three saves, 18 holds, three blown saves and a 9-4 record as one of the Padres' top relievers.
