Fantasy baseball closer breakouts, sleepers, waiver wire add/drop analysis for Week 21 of 2026 include Kodai Senga, Hogan Harris, Mason Montgomery, Jordan Romano, Steven Cruz, and more.
The closer landscape has begun to shift in fantasy baseball. With the trade deadline now several weeks behind us, some new high-leverage options have begun to claim ninth-inning roles.
In this piece, we will look at five relief pitchers who have seen their first value increase over the last week of action and determine if they are worth picking up in standard leagues.

Kodai Senga, New York Mets
New York Mets relief pitcher Kodai Senga earned his second save in five days Friday, tossing a scoreless ninth in a 4-1 win over Washington. He allowed one hit and struck out one, and the usage was notable after Daniel Duarte handled the eighth. Senga also converted a save Monday in Atlanta and has now put together four straight scoreless relief appearances. His season numbers are still rough at a 7.95 ERA and 1.68 WHIP, so there is obvious risk attached.
But Devin Williams (shoulder) is on the 15-day injured list and isn't expected back until September, leaving save chances up for grabs. Senga has gotten two of them already, and Friday's ninth-inning assignment only adds to the intrigue. Yahoo still has him rostered in just 16% of leagues. Managers chasing saves in deeper formats should have him on the radar while the Mets sort out the back end.

Hogan Harris, Athletics
Athletics relief pitcher Hogan Harris worked a scoreless ninth Friday, August 14, to finish an 8-3 win over the Texas Rangers. It wasn't a save situation, but the usage keeps him at the front of a bullpen that has bounced around much of the season. Harris has 11 saves, including back-to-back conversions in Boston on August 8 and 9, and RotoBaller currently lists him as the Athletics' closer.
There are rough edges. Harris has walked 34 batters in 53 innings and carries a 1.55 WHIP, but he's also struck out 70 with a 3.57 ERA. That's enough swing-and-miss to keep him useful while he gets the bulk of the ninth-inning work. Harris is rostered in only 13% of Yahoo leagues, even though RotoBaller ranks him 23rd among closers for Week 21. He's best suited for 15-team leagues, but anyone digging for saves should know the job is leaning his way.

Mason Montgomery, Pittsburgh Pirates
Pittsburgh Pirates relief pitcher Mason Montgomery picked up his fourth save of the season Friday, getting the final out of an 8-4 win over the Boston Red Sox. Kirby Yates opened the ninth with no save opportunity but gave up three straight two-out singles, bringing Montgomery in with two runners aboard and the tying run on deck. The left-hander struck out Adley Rutschman to finish it.
Three of Montgomery's four saves have now come over his last seven appearances. Montgomery has been rolling lately, posting a 1.32 ERA, 0.66 WHIP, and 27 strikeouts across his last 13 2/3 innings. Pittsburgh still hasn't settled on one closer, with Gregory Soto and Luke Weaver also getting late-inning looks. Montgomery keeps finding his way into save chances, though, and the strikeouts give him something to offer even when the ninth goes elsewhere. At 10% rostered on Yahoo, he's worth chasing in deeper leagues for managers who need saves.

Steven Cruz, Kansas City Royals
Kansas City Royals relief pitcher Steven Cruz picked up his fourth save Friday, August 14, working a scoreless ninth in a 7-6 win over the Los Angeles Angels. Cruz allowed one hit and struck out one, freezing Mike Trout for the final out. It was another ninth-inning chance for the right-hander, who has now recorded all four of his saves over his last 15 appearances.
Cruz has been much better than his 4.17 season ERA suggests lately, posting a 2.40 ERA and 0.87 WHIP across those 15 outings. Alex Lange has moved into lower-leverage work, while Cruz has been getting the ninth more often. The job isn't completely secure yet, but Cruz is clearly the arm to chase from this bullpen right now. Yahoo managers haven't moved much yet, either, with Cruz rostered in just 6% of leagues. He's worth grabbing in deeper formats for anyone looking to add saves.

Jordan Romano, Colorado Rockies
Colorado Rockies relief pitcher Jordan Romano has 12 saves this season, including eight since the Rockies selected his contract on July 4. He converted his latest chance Wednesday against Arizona, working around a two-out walk in a scoreless ninth to finish a 6-4 win. Romano has gone eight-for-nine in save opportunities with Colorado and owns a 3.09 ERA with 14 strikeouts in 11 2/3 innings for the club.
The walks are still something fantasy managers have to live with. Romano has issued seven of them during his Rockies stint, contributing to a 1.54 WHIP, but Colorado keeps handing him the ninth. RotoBaller currently lists the bullpen as solid with Romano on top, and he sits 25th in its Week 21 closer rankings. Even so, Yahoo has him rostered in just 12% of leagues. Romano fits best as an add in 15-team formats, especially for managers who need another steady path to saves.
