The Rays optioned Sulser to Triple-A Durham on Monday, Marc Topkin of the Tampa Bay Times reports.

Sulser hasn't allowed a run in 11.2 innings with the Rays, but he has minor-league options remaining and that works against him. Colin Poche (shoulder) has returned from the 15-day injured list in a corresponding move.

The Rays activated Poche (shoulder) from the 15-day injured list Monday, Marc Topkin of the Tampa Bay Times reports.

Poche has been out all month with left shoulder inflammation but will skip a rehab assignment and go directly back into the big-league bullpen. The left-hander could be in the mix for saves down the stretch as part of an unsettled Tampa Bay closer situation.

Karinchak (shoulder) began a rehab assignment at Triple-A Columbus on Sept. 6 and has struck out seven batters over 4.2 innings across five appearances while giving up two earned runs on two hits and five walks.

Karinchak has been on the injured list all season after reporting shoulder fatigue in spring training and being slow to recover from the issue and return to form. While working out at the Guardians' facility in Arizona in August, Karinchak seemed to turn a corner with his rehab program and was given the green light to report to Triple-A earlier this month. His results have been uneven thus far, but manager Stephen Vogt hasn't dismissed the possibility of Karinchak being an option out of the big-league bullpen before the regular season ends Sept. 29, per MLB.com.

Sims (lat) walked two and recorded a strikeout in one-third of an inning in his first rehab appearance with Triple-A Worcester on Sunday.

Sims is three weeks removed from going on the 15-day injured list with a right lat strain, but he's ramping up in the minors and could be ready to rejoin the Boston bullpen by the end of the week. The right-hander has struggled with Boston since being acquired at the trade deadline, allowing nine runs with a 7:7 K:BB over 10 innings.

Ellard pitched the ninth inning and earned a save against Oakland on Sunday. He struck out one and allowed a solo homer.

Ellard coughed up a solo shot to Shea Langeliers but still escaped with his first career save. The White Sox continue to spread ninth-inning work around the bullpen when a rare save opportunity presents itself. With Jordan Leasure (shoulder) still on the injured list, no active pitcher on the roster has multiple saves this season. Ellard owns a 3.06 ERA with a 22:8 K:BB through 18 MLB appearances.

Green allowed two hits in a scoreless inning Sunday, striking out one and earning a save against the Cardinals.

Green gave up a pair of singles but forced a Jordan Walker pop-out to close out the 3-2 win. Green made his first appearance since coughing up four runs in a loss against the Mets on Sept. 11. It was also his first converted save chance since Aug. 29 after blowing his previous three in September. Green owns a 3.42 ERA with a 44:14 K:BB through 50 innings.

Hader allowed a hit and struck out one without being charged with a run over two-thirds of an inning to earn the save in Sunday's 6-4 win over the Angels.

Hader inherited a bases-loaded situation with one out and let all three inherited runners score, but he was able to avoid a total collapse. Caleb Ferguson was charged with all three runs, so Hader was able to log his third scoreless outing over five appearances in September. The closer has 31 saves in 33 chances this year while pitching to a 3.32 ERA, 0.92 WHIP and 96:22 K:BB through 65 innings.

Clase struck out one batter in a perfect inning and earned a save over the Rays on Sunday.

Clase needed only 12 pitches (nine strikes) to roll through the Rays for his 45th save of the year. The star closer has converted 32 consecutive save chances dating back to May 20. Clase has been remarkably consistent this season, posting a 0.66 ERA with a 61:8 K:BB through 68.1 frames.

Holton worked around a hit and a walk to toss 1.1 scoreless innings of relief and earn a hold in Sunday's 4-2 win over the Orioles. He struck out one.

Holton has been generating fantasy value in multiple ways recently. The lefty earned a win in relief Wednesday, picked up a save on Friday and then recorded his 13th hold of the season Sunday, as he entered in the sixth inning to face the heart of Baltimore's lineup in a close game. Holton lowered his ERA to a stellar 2.17 in the process, and he should continue to be a valuable bullpen weapon for the Tigers.

Basso is listed as the Athletics' scheduled starting pitcher for Wednesday's game against the Cubs at Wrigley Field.

Basso will make another turn through the rotation after he was summoned from Triple-A Las Vegas this past week to replace injured starter Osvaldo Bido (wrist). Through his first two MLB starts, Basso has struck out eight while allowing 10 baserunners over 11.1 scoreless innings, though his outings came against two of MLB's weaker offenses in the Tigers and White Sox. The road matchup with the Cubs will represent the 26-year-old lefty's toughest test to date.
