Rumbelow was optioned to Double-A Arkansas on Tuesday, Ryan Divish of The Seattle Times reports.

Rumbelow made just one appearance during his most recent stint with the Mariners, allowing one run across three innings of relief against the Astros last week. He now owns an unremarkable 6.75 ERA across 13.1 big-league innings this season. The 26-year-old should be back in the majors when a fresh bullpen arm is needed.

Chapman received a second PRP injection in his left knee Tuesday, Bryan Hoch of MLB.com reports.

Manager Aaron Boone said this was part of the original plan after Chapman received the first injection last week. The Yankees still intend to re-evaluate him in a week or two, after which there will hopefully be a more concrete timetable for his return. Until then, Boone will mix and match between Dellin Betances, Zach Britton and David Robertson in the ninth inning.

Mengden fired four scoreless innings in a loss to the Astros on Monday, allowing four hits and two walks while recording two strikeouts.

The right-hander had just been summoned from Triple-A Nashville earlier in the day, with an eye on having him log a start Thursday in place of Sean Manaea (shoulder). However, the 64 pitches Mengden threw Monday likely scuttles that plan, Jane Lee of MLB.com reports, although the veteran is still a likely candidate to take Manaea's rotation spot should the latter be sidelined for a prolonged period of time.

Manaea (shoulder) will be evaluated by Dr. Neal ElAttrache on Tuesday, Susan Slusser of the San Francisco Chronicle reports.

Manaea landed on the disabled list Sunday with a left shoulder impingement, and after getting an MRI on Monday, he'll leave it to Dr. ElAttrache to determine the extent of the injury. The fact that Manaea is scheduled to see one of the top surgeons in pro sports is not good news, as it likely suggests that he's dealing with a serious injury. More news on Manaea's availability moving forward should emerge later this week.

Santos was designated for assignment by the Blue Jays on Monday, Shi Davidi of Sportsnet.ca reports.

Santos was dropped from the team's 40-man roster to free up a spot for Murphy Smith, whose contract was selected from Triple-A Buffalo in a corresponding roster move. The 27-year-old Santos compiled a solid 2.85 ERA across 41 innings with the Bisons this season, though his 7.20 ERA across 20 big-league innings likely rendered him expendable. He'll likely report back to Buffalo should he pass through waivers untouched.

Devenski (hamstring) will make a minor-league rehab appearance with Double-A Corpus Christi on Thursday, Jake Kaplan of The Athletic Houston reports.

Devenski, who has been on the DL since Aug. 3 with a hamstring issue, has already made five rehab appearances -- three with the Hooks and two with Triple-A Fresno -- struggling to a 7.71 ERA across 4.2 innings in those outings. He'll make one more appearance with Corpus Christi later in the week, and if everything goes off without a hitch he'll likely be cleared to rejoin the Astros on Saturday when rosters expand.

Barnes was recalled from Triple-A Buffalo on Monday, Mike Wilner of Sportsnet 590 The Fan reports.

Barnes will rejoin the big club to offer a fresh arm out of the bullpen after the team used five relievers during Sunday's loss. The right-hander owns a 4.50 ERA across 32 innings with the Blue Jays this season.

Mengden was recalled from Triple-A Nashville on Monday, Julian McWilliams of The Athletic Bay Area reports.

Mengden will swap places with Sunday's spot starter, Chris Bassitt, who was sent to Nashville in a corresponding move. The right-hander figures to offer length out of the bullpen during the team's upcoming series against the Astros which starts Monday, though he could also be an option to start in place of the injured Sean Manaea (shoulder) on Friday if he goes unused in relief. Mengden, who was sent to the minors after a three-week stint on the disabled list with a sprained foot -- despite his serviceable 4.47 ERA across 16 starts with the A's -- compiled a 2.98 ERA across nine starts (45.1 innings) with the Sounds before being summoned back to the big club.

Beeks is likely to serve as the long man in Wednesday's scheduled "bullpen day" once probable opener Diego Castillo exits, Marc Topkin of the Tampa Bay Times reports.

The young lefty has enjoyed a solid month after a rough Rays debut July 28, an outing in which he allowed eight earned runs on 10 hits over 3.1 innings to the Orioles. Beeks has bounced back to the tune of a 2.96 ERA and 22 strikeouts over 24.1 August frames while being utilized exclusively as a long reliever.

Lopez (0-4) allowed five runs on five hits and three walks across four innings Sunday to take the loss against Cleveland. He struck out four.

Lopez coasted through the first three innings but was knocked around for five runs on four hits, two walks and a wild pitch in the fourth. He escaped the inning but was lifted prior to the fifth, with his pitch count already sitting at 79. Lopez was coming off a tough-luck loss to the Rays in his previous outing, but overall he's posted an ugly 7.91 ERA through three starts with his new club. He's tentatively scheduled to start this weekend against the Orioles, but his place in the rotation could be in jeopardy if he fails to attain a better result.
