Welcome to the RP Roundup, my daily fantasy baseball article reviewing every reliever performance from the previous day.
CLE 4 – DET 6
| Cleveland Guardians | |||||||
|---|---|---|---|---|---|---|---|
| Matt Festa | 0.2 IP | 0 ER | 1 H | 0 BB | 1 K | 1 Whiffs | 9% CSW |
| Franco Aleman | 1.0 IP | 0 ER | 0 H | 1 BB | 1 K | 2 Whiffs | 29% CSW |
- Franco Aleman — Four-Seamer down 1.1 MPH (95.1 vs. 96.2 season avg). This is not as fun. If the stuff ticks back up again, then we’ll talk.
| Detroit Tigers | |||||||
|---|---|---|---|---|---|---|---|
| Jacob Waguespack – W (1) | 2.0 IP | 0 ER | 2 H | 1 BB | 0 K | 0 Whiffs | 24% CSW |
| Drew Sommers – HLD (8) | 0.2 IP | 0 ER | 1 H | 1 BB | 1 K | 2 Whiffs | 33% CSW |
| Kyle Finnegan – HLD (13) | 1.0 IP | 1 ER | 1 H | 1 BB | 0 K | 1 Whiffs | 18% CSW |
| Tyler Holton – HLD (11) | 0.1 IP | 0 ER | 0 H | 0 BB | 0 K | 1 Whiffs | 50% CSW |
| Kenley Jansen – SV (14) | 1.0 IP | 1 ER | 1 H | 2 BB | 0 K | 1 Whiffs | 10% CSW |
- Kenley Jansen had some impressively poor command here, as only 9 of his 29 pitches were in the zone. Maybe (hopefully?) just a one-off, but something to keep an eye on.

PIT 0 – MIA 2
| Pittsburgh Pirates | |||||||
|---|---|---|---|---|---|---|---|
| Yohan Ramírez | 3.0 IP | 0 ER | 0 H | 1 BB | 5 K | 4 Whiffs | 35% CSW |
- Yohan Ramírez — Four-Seamer down 0.8 MPH (95.8 vs. 96.6 season avg). The sweeper and fastball were more than good enough here, despite a small velo dip.
| Miami Marlins | |||||||
|---|---|---|---|---|---|---|---|
| Michael Petersen – HLD (19) | 1.0 IP | 0 ER | 1 H | 0 BB | 2 K | 5 Whiffs | 38% CSW |
| Pete Fairbanks – SV (18) | 1.0 IP | 0 ER | 0 H | 0 BB | 1 K | 2 Whiffs | 25% CSW |
- Pete Fairbanks — Slider usage 50% (+28 pts vs. 22% usual). Fairbanks used his slider as a strike getter here, as he had trouble commanding the fastball.
CHC 8 – WSN 6
| Chicago Cubs | |||||||
|---|---|---|---|---|---|---|---|
| Ryan Rolison – W (7) | 1.1 IP | 0 ER | 1 H | 0 BB | 1 K | 2 Whiffs | 38% CSW |
| Trent Thornton – HLD (4) | 1.0 IP | 0 ER | 0 H | 0 BB | 2 K | 0 Whiffs | 20% CSW |
| Ryan Zeferjahn | 0.2 IP | 2 ER | 3 H | 1 BB | 0 K | 1 Whiffs | 26% CSW |
| Jacob Webb – SV (8) | 1.1 IP | 0 ER | 1 H | 0 BB | 2 K | 8 Whiffs | 50% CSW |
- Trent Thornton — Four-Seamer up 1.8 MPH (96.8 vs. 95.0 season avg). The velocity increase brings his fastball closer to average. The curveball does the bulk of the heavy lifting.
- Cubs fans getting their first taste of the Ryan Zeferjahn rollercoaster.
- Jacob Webb may not give back the closer role when Palencia (who had a rough AA outing yesterday) returns at this point.

| Washington Nationals | |||||||
|---|---|---|---|---|---|---|---|
| Tom Cosgrove | 0.2 IP | 0 ER | 1 H | 0 BB | 1 K | 1 Whiffs | 10% CSW |
| Max Kranick | 1.0 IP | 1 ER | 2 H | 2 BB | 0 K | 4 Whiffs | 20% CSW |
| Orlando Ribalta | 1.0 IP | 1 ER | 1 H | 1 BB | 0 K | 1 Whiffs | 27% CSW |
| Miles Mikolas | 3.0 IP | 1 ER | 1 H | 0 BB | 2 K | 2 Whiffs | 28% CSW |
- Tom Cosgrove — Four-Seamer down 1.1 MPH (87.1 vs. 88.2 season avg); Four-Seamer usage 50% (+27 pts vs. 23% usual)
- Miles Mikolas — Four-Seamer up 1.2 MPH (94.4 vs. 93.2 season avg). For those wondering…no.
SEA 1 – NYY 4
| Seattle Mariners | |||||||
|---|---|---|---|---|---|---|---|
| José A. Ferrer – HLD (11) | 1.0 IP | 0 ER | 0 H | 0 BB | 2 K | 3 Whiffs | 31% CSW |
| Michael Rucker – L (4) | 0.1 IP | 4 ER | 3 H | 1 BB | 1 K | 1 Whiffs | 20% CSW |
| Eduard Bazardo | 0.2 IP | 0 ER | 2 H | 0 BB | 0 K | 1 Whiffs | 11% CSW |
| Seranthony Domínguez | 1.0 IP | 0 ER | 0 H | 1 BB | 0 K | 2 Whiffs | 12% CSW |
- José A. Ferrer — Sinker up 1.0 MPH (98.4 vs. 97.4 season avg)
- Michael Rucker — Four-Seamer up 0.8 MPH (96.9 vs. 96.1 season avg). Rucker finally got a chance to pitch in a meaningful leverage spot, and well, it did not go well.
| New York Yankees | |||||||
|---|---|---|---|---|---|---|---|
| Tim Hill – W (4) | 1.1 IP | 0 ER | 0 H | 0 BB | 0 K | 0 Whiffs | 0% CSW |
| Brent Headrick – HLD (18) | 1.0 IP | 0 ER | 0 H | 0 BB | 2 K | 3 Whiffs | 44% CSW |
| David Bednar – SV (27) | 1.0 IP | 0 ER | 1 H | 0 BB | 2 K | 7 Whiffs | 42% CSW |
- David Bednar’s fastball looked great here, and the splitter did its thing as usual.
BOS 3 – TOR 5
| Boston Red Sox | |||||||
|---|---|---|---|---|---|---|---|
| Tyron Guerrero | 1.0 IP | 0 ER | 0 H | 0 BB | 1 K | 1 Whiffs | 33% CSW |
| Seth Martinez | 1.0 IP | 1 ER | 2 H | 0 BB | 1 K | 4 Whiffs | 45% CSW |
- Seth Martinez has a good sweeper, but that’s about it. Nothing to see here.
| Toronto Blue Jays | |||||||
|---|---|---|---|---|---|---|---|
| Chase Lee – W (1) | 1.2 IP | 0 ER | 1 H | 2 BB | 0 K | 0 Whiffs | 28% CSW |
| Brendon Little – HLD (3) | 0.1 IP | 0 ER | 0 H | 0 BB | 1 K | 1 Whiffs | 33% CSW |
| Braydon Fisher – HLD (12) | 1.0 IP | 0 ER | 0 H | 1 BB | 0 K | 2 Whiffs | 27% CSW |
| Spencer Miles – SV (1) | 1.0 IP | 0 ER | 1 H | 0 BB | 0 K | 0 Whiffs | 29% CSW |
- Spencer Miles — Sinker up 2.0 MPH (98.2 vs. 96.2 season avg). Miles got a nice velocity boost here (#SaveChanceEnergy), and I do see a patch to reliever success with his sinker/slider (curveballs meh).
NYM 0 – ATL 4
| New York Mets | |||||||
|---|---|---|---|---|---|---|---|
| Jefry Yan | 0.2 IP | 1 ER | 0 H | 3 BB | 0 K | 3 Whiffs | 20% CSW |
| Chayce McDermott | 1.1 IP | 2 ER | 2 H | 1 BB | 1 K | 4 Whiffs | 28% CSW |
- Jefry Yan — Sinker down 1.2 MPH (96.8 vs. 98.0 season avg). The command may be even worse than I thought.
- Chayce McDermott — Four-Seamer down 1.0 MPH (94.9 vs. 95.9 season avg). Boo
| Atlanta Braves | |||||||
|---|---|---|---|---|---|---|---|
| Didier Fuentes – HLD (13) | 1.0 IP | 0 ER | 0 H | 0 BB | 1 K | 3 Whiffs | 43% CSW |
| Dylan Lee – HLD (27) | 1.0 IP | 0 ER | 0 H | 0 BB | 1 K | 3 Whiffs | 42% CSW |
| Raisel Iglesias | 1.0 IP | 0 ER | 0 H | 0 BB | 1 K | 1 Whiffs | 21% CSW |
- Raisel Iglesias had a nice clean inning here, but I still get the sense the walls may be closing in, especially with the way Fuentes (not to mention Lee) has been throwing.

BAL 5 – MIN 2
| Baltimore Orioles | |||||||
|---|---|---|---|---|---|---|---|
| Josh Walker – HLD (1) | 1.0 IP | 0 ER | 0 H | 0 BB | 1 K | 0 Whiffs | 25% CSW |
| Yennier Cano – HLD (11) | 1.0 IP | 0 ER | 1 H | 1 BB | 1 K | 2 Whiffs | 32% CSW |
| Andrew Kittredge – SV (6) | 1.0 IP | 0 ER | 0 H | 0 BB | 1 K | 1 Whiffs | 22% CSW |
- Josh Walker — Sinker up 0.9 MPH (93.0 vs. 92.1 season avg)
- The slider has been looking better lately for Andrew Kittredge, but it was the sinker that was responsible for the Whiff and CSW% here. Low upside, but it does appear that Kittredge is the favorite for saves here.
| Minnesota Twins | |||||||
|---|---|---|---|---|---|---|---|
| Kody Funderburk | 1.0 IP | 0 ER | 2 H | 1 BB | 1 K | 6 Whiffs | 41% CSW |
| Tommy Nance | 1.0 IP | 0 ER | 1 H | 0 BB | 2 K | 3 Whiffs | 44% CSW |
| Taylor Rogers | 1.0 IP | 0 ER | 0 H | 1 BB | 2 K | 1 Whiffs | 39% CSW |
- Kody Funderburk holds a 0.51 ERA, 0.79 WHIP, and 32% K rate over 17.2 IP since the start of July. He has just one hold over this span, but that could change the way he’s been throwing.
CIN 5 – CHW 4
| Cincinnati Reds | |||||||
|---|---|---|---|---|---|---|---|
| Luis Mey | 2.0 IP | 0 ER | 0 H | 0 BB | 2 K | 3 Whiffs | 52% CSW |
| Pierce Johnson | 1.0 IP | 0 ER | 0 H | 0 BB | 1 K | 1 Whiffs | 38% CSW |
| Tejay Antone | 1.0 IP | 0 ER | 1 H | 0 BB | 0 K | 1 Whiffs | 33% CSW |
| Brock Burke – W (5) | 1.0 IP | 0 ER | 0 H | 0 BB | 2 K | 1 Whiffs | 17% CSW |
| Emilio Pagán – SV (14) | 1.0 IP | 0 ER | 0 H | 0 BB | 1 K | 2 Whiffs | 12% CSW |
- Luis Mey’s stuff was down a bit here, but the command was much improved, so we’ll take it.
| Chicago White Sox | |||||||
|---|---|---|---|---|---|---|---|
| Bryan Hudson | 0.0 IP | 3 ER | 3 H | 0 BB | 0 K | 0 Whiffs | 20% CSW |
| Grant Taylor – BS (4) | 2.0 IP | 0 ER | 1 H | 1 BB | 2 K | 3 Whiffs | 31% CSW |
| Sean Newcomb – L (3) | 1.0 IP | 0 ER | 0 H | 0 BB | 0 K | 0 Whiffs | 20% CSW |
- Bryan Hudson — Four-Seamer up 0.8 MPH (92.9 vs. 92.1 season avg).
- Sean Newcomb — Four-Seamer down 1.4 MPH (93.2 vs. 94.6 season avg). That’s not great.
PHI 0 – STL 2
| Philadelphia Phillies | |||||||
|---|---|---|---|---|---|---|---|
| Alex McFarlane – L (1) | 1.0 IP | 1 ER | 1 H | 1 BB | 1 K | 3 Whiffs | 35% CSW |
| Tim Mayza | 1.0 IP | 1 ER | 1 H | 0 BB | 1 K | 2 Whiffs | 31% CSW |
- Alex McFarlane’s command was not great here, but the stuff is worth the Phillies giving him an extended look, especially with their right-handed bullpen depth thin at the moment.
| St. Louis Cardinals | |||||||
|---|---|---|---|---|---|---|---|
| George Soriano – W (6) | 1.0 IP | 0 ER | 1 H | 1 BB | 2 K | 2 Whiffs | 35% CSW |
| Caleb Ferguson | 0.0 IP | 0 ER | 0 H | 3 BB | 0 K | 2 Whiffs | 14% CSW |
| Ryne Stanek – HLD (22) | 1.0 IP | 0 ER | 0 H | 0 BB | 0 K | 0 Whiffs | 0% CSW |
| Riley O’Brien – SV (30) | 1.0 IP | 0 ER | 0 H | 0 BB | 1 K | 1 Whiffs | 50% CSW |
- Caleb Ferguson — Sinker down 1.2 MPH (91.1 vs. 92.3 season avg). And no command? Oof.
- Riley O’Brien — Sinker down 1.2 MPH (96.8 vs. 98.0 season avg). O’Brien is now up to 30 saves, but how much longer can he survive with the diminished stuff/command?

TEX 2 – LAA 3
| Texas Rangers | |||||||
|---|---|---|---|---|---|---|---|
| Chase Silseth | 1.0 IP | 0 ER | 0 H | 0 BB | 2 K | 4 Whiffs | 45% CSW |
- Chase Silseth — Four-Seamer usage 73% (+34 pts vs. 38% usual). It worked here, but this isn’t the answer.
| Los Angeles Angels | |||||||
|---|---|---|---|---|---|---|---|
| Tayler Saucedo | 0.2 IP | 1 ER | 1 H | 1 BB | 1 K | 4 Whiffs | 27% CSW |
| Luke Murphy – HLD (3) | 1.2 IP | 0 ER | 2 H | 1 BB | 0 K | 1 Whiffs | 15% CSW |
| José Fermin – W (4) | 1.1 IP | 0 ER | 0 H | 0 BB | 3 K | 3 Whiffs | 50% CSW |
| Samy Natera Jr. – SV (3) | 1.0 IP | 0 ER | 0 H | 0 BB | 2 K | 1 Whiffs | 36% CSW |
- José Fermin — Sinker down 1.4 MPH (95.0 vs. 96.4 season avg). I’ll take lower velocity from Fermin if it has him locating like this.
- Samy Natera Jr. didn’t even have his best stuff here pitching on back-to-back days, but still made it work. I may be nitpicking because the fastball is so good, but I’d love to see more sliders from him still.
COL 3 – ARI 2
| Colorado Rockies | |||||||
|---|---|---|---|---|---|---|---|
| Jimmy Herget – HLD (6) | 1.0 IP | 0 ER | 1 H | 0 BB | 0 K | 1 Whiffs | 21% CSW |
| Brennan Bernardino – HLD (9) | 1.0 IP | 0 ER | 0 H | 0 BB | 1 K | 1 Whiffs | 23% CSW |
| Jordan Romano – SV (11) | 1.0 IP | 0 ER | 1 H | 0 BB | 1 K | 1 Whiffs | 35% CSW |
- Jordan Romano — Four-Seamer down 0.9 MPH (93.1 vs. 94.0 season avg). I just don’t think we can expect this to continue, right? The rest of season schedule after this weekend is not great either.

| Arizona Diamondbacks | |||||||
|---|---|---|---|---|---|---|---|
| Kevin Ginkel – L (4) | 1.0 IP | 1 ER | 1 H | 0 BB | 2 K | 6 Whiffs | 46% CSW |
| Taylor Clarke | 1.0 IP | 0 ER | 0 H | 0 BB | 1 K | 1 Whiffs | 22% CSW |
| Juan Morillo | 1.0 IP | 0 ER | 1 H | 1 BB | 0 K | 0 Whiffs | 9% CSW |
- This might be the best Kevin Ginkel’s slider has looked all year, but Goodman got him on a fastball up in the zone for a leadoff triple.
TBR 12 – ATH 4
| Athletics | |||||||
|---|---|---|---|---|---|---|---|
| Brady Basso | 2.0 IP | 1 ER | 3 H | 0 BB | 2 K | 3 Whiffs | 28% CSW |
| Elvis Alvarado | 1.0 IP | 2 ER | 1 H | 1 BB | 1 K | 2 Whiffs | 19% CSW |
| Yunior Tur | 2.0 IP | 3 ER | 2 H | 0 BB | 3 K | 4 Whiffs | 33% CSW |
- Elvis Alvarado left a 1-0 fastball down to Mesa here for a two-run home run, and I think we need to treat the A’s relievers similarly to the Rockies and just stay away, especially at home.
MIL 2 – SDP 11
| Milwaukee Brewers | |||||||
|---|---|---|---|---|---|---|---|
| Bryse Wilson | 2.1 IP | 3 ER | 5 H | 0 BB | 2 K | 4 Whiffs | 33% CSW |
| Gary Sánchez | 1.0 IP | 0 ER | 2 H | 0 BB | 0 K | 1 Whiffs | 21% CSW |
- Bryse Wilson — Sinker down 0.9 MPH (91.5 vs. 92.4 season avg). Nope.
| San Diego Padres | |||||||
|---|---|---|---|---|---|---|---|
| Wandy Peralta | 1.0 IP | 0 ER | 1 H | 0 BB | 0 K | 0 Whiffs | 7% CSW |
| Griffin Canning | 2.0 IP | 1 ER | 3 H | 1 BB | 2 K | 7 Whiffs | 31% CSW |
- Griffin Canning — Four-Seamer up 1.0 MPH (95.5 vs. 94.5 season avg). I still believe there’s a solid reliever future for Canning, it just may not be this season.
HOU 1 – SFG 4
| Houston Astros | |||||||
|---|---|---|---|---|---|---|---|
| Enyel De Los Santos | 0.2 IP | 1 ER | 2 H | 0 BB | 0 K | 1 Whiffs | 36% CSW |
| Bennett Sousa | 1.1 IP | 0 ER | 1 H | 0 BB | 3 K | 5 Whiffs | 58% CSW |
| AJ Blubaugh | 1.0 IP | 0 ER | 1 H | 0 BB | 1 K | 2 Whiffs | 28% CSW |
- Bennett Sousa went 16/19 sliders here, which is probably for the best, with the fastball still a bit down from his 2025 numbers.
| San Francisco Giants | |||||||
|---|---|---|---|---|---|---|---|
| Carson Seymour – HLD (2) | 2.0 IP | 0 ER | 1 H | 0 BB | 2 K | 4 Whiffs | 30% CSW |
| Reiver Sanmartin – HLD (1) | 0.1 IP | 0 ER | 0 H | 0 BB | 0 K | 2 Whiffs | 40% CSW |
| JT Brubaker – SV (2) | 1.0 IP | 0 ER | 0 H | 0 BB | 0 K | 0 Whiffs | 29% CSW |
- Carson Seymour — Sinker up 1.1 MPH (96.8 vs. 95.7 season avg).
- JT Brubaker — Sinker up 0.8 MPH (94.4 vs. 93.6 season avg). Brubaker got the call in the ninth with Smith down for the night, and the increased velocity is nice, but the stuff still grades out terribly.
KCR 4 – LAD 5
| Kansas City Royals | |||||||
|---|---|---|---|---|---|---|---|
| Steven Cruz | 1.1 IP | 1 ER | 1 H | 1 BB | 1 K | 1 Whiffs | 12% CSW |
| Nate Pearson | 1.0 IP | 0 ER | 0 H | 0 BB | 2 K | 3 Whiffs | 55% CSW |
| Lucas Erceg – L (4) | 0.1 IP | 0 ER | 1 H | 2 BB | 0 K | 1 Whiffs | 14% CSW |
- Steven Cruz — Four-Seamer up 1.1 MPH (99.5 vs. 98.4 season avg); Four-Seamer usage 33% (-26 pts vs. 59% usual). A walk, a hit by pitch, and an opposite-field bloop single were responsible for the run here, but the stuff was still solid.
- Nate Pearson got the ninth inning again in an interesting development. Maybe he’s just the sole closer here at the moment? At his best, Pearson’s fastball and breakers are good enough for success in this role…but can the command be consistent enough?
- Lucas Erceg — Four-Seamer up 0.9 MPH (98.0 vs. 97.1 season avg). Does it matter?
| Los Angeles Dodgers | |||||||
|---|---|---|---|---|---|---|---|
| Alex Vesia | 1.0 IP | 0 ER | 0 H | 1 BB | 1 K | 1 Whiffs | 33% CSW |
| Evan Phillips – BS (2) | 0.1 IP | 2 ER | 3 H | 1 BB | 1 K | 3 Whiffs | 31% CSW |
| Jack Dreyer | 0.2 IP | 0 ER | 0 H | 0 BB | 1 K | 1 Whiffs | 33% CSW |
| Edgardo Henriquez | 1.0 IP | 0 ER | 0 H | 0 BB | 1 K | 2 Whiffs | 30% CSW |
| Seth Halvorsen – W (1) | 1.0 IP | 0 ER | 0 H | 1 BB | 0 K | 0 Whiffs | 18% CSW |
- Seth Halvorsen — Four-Seamer up 1.8 MPH (100.7 vs. 98.9 season avg). They can’t keep getting away with this.
