Fantasy Baseball Closer Confidential for Week 10 2026: Jansen and Erceg Are Vulnerable

Three closers just graduated to Secure. One more is on the doorstep. The boys of summer are taking over - and we've triple-checked every grade before ringing the final bell.

The calendar flips to June this week, which means it is time for this column to do what any good teacher does at the end of the school year: review the gradebook one final time, hand out diplomas where they've been earned, send the troublemakers to summer school, and lock the classroom door on a few situations that were never going to get their act together.

Aside from graduations, this is also our spring cleaning edition. We have scrubbed every grade against the full weight of the Closer Confidential criteria - recent performance, news and noise, manager's comments, what's under the hood, the hierarchy behind each arm, and team context. Every number that survived that review earned its place. Every number that didn't has been adjusted accordingly. The save landscape entering June looks more settled at the top than it has at any point this season, and considerably more chaotic at the bottom than we would like.

Buckle up. We have diplomas to hand out and some unpleasant news to deliver before summer vacation officially begins. By "vacation" we mean "dog days." Let's go.

Reviewing the Categories

In the weekly Closer Confidential column, we group closers and committees into three cohorts:

Secure: 90 and Above - Low-to-no risk; good results, strong underlying statistics, in a good bullpen situation

Shaky: 80-89 - Some doubt exists, often with inconsistent supporting skills and stats

Seesaw: 79 and Below - Committees and closers in trouble. The ninth inning is, or should be, in doubt.

Secure Closers

This is Graduation Day. Three closers walk across the stage this week, and we want to explain each one because these are not casual bumps - they are promotions earned by surviving the full criteria review.

Mason Miller remains in a tier of his own. He has 17 saves, the cleanest profile in baseball, and the only thing worth monitoring this month is a modest uptick in May walks compared to April. Through his first 15 appearances he issued three walks total. In May, he issued eight. He is still wildly dominant and his 10-game scoreless streak remains intact, but the column watches the walk rate so you don't have to. Grade unchanged. He is simply not comparable to anyone else on this list.

Cade Smith reaches 20 saves this week - the first reliever in baseball to get there - and has converted 18 consecutive save opportunities. Erik Sabrowski went to the IL with left elbow inflammation, thinning the bullpen around him, but there is no arm in Cleveland that constitutes a hierarchy threat. Smith gets a bump to 95. He is as automatic as anyone not named Mason Miller.

Raisel Iglesias graduates. Two saves this week, nine on the season, and Robert Suarez is a capable but non-threatening backup. The Braves late-inning situation is one of the better-constructed ones in the National League and Iglesias has been a model of consistency all month. Welcome to Secure. And we haven't even mentioned Dylan Lee, who arguably has been better than both Iglesias and Suarez in most metrics this year.

Jhoan Duran graduates- and earns the biggest single-week jump in the tier. This one requires a note because the three-point move is larger than our normal incremental adjustments. The reason is simple: the oblique. We kept Duran in Shaky last week specifically because of his injury history with that muscle group, and we said we needed to see ten consecutive healthy appearances before we'd graduate him. He gave us that and then some. Since returning from the IL on May 5, he has allowed two runs across ten outings - 7 hits, 18 strikeouts, 5 walks - and is a perfect 11-for-11 in save opportunities on the season. The ERA is 1.62. The FIP is 1.87. There is no gap. The three-point move is the oblique penalty being lifted in full. He has earned it. Diploma in hand.

Devin Williams graduates. He came into 2026 with question marks attached - the Mets' bullpen situation looked disorganized, A.J. Minter was hurt, and the role felt tenuous for the first month. It no longer feels tenuous. Williams has been steady, his underlying numbers have trended in the right direction all month, and Luke Weaver and Brooks Raley form a genuine setup infrastructure behind him, with AJ Minter back from injury and ramping up to full form. Williams crosses the stage with honors, and a 90 grade. The Mets' bullpen is no longer a source of ambient concern - it is now one of the more functional late-inning constructions in the NL East.

Seven closers in Secure. That is the most this column has counted at any point in 2026. Remember it, because the Shaky and Seesaw tiers below are going to make you appreciate the top of the market even more.

Shaky Closers

The spring cleaning in this tier cuts in both directions - a few arms scrubbed their way to better grades, a few more got scrubbed down.

Andrés Muñoz drops three spots, and the column wants to be precise about why, because this is exactly the kind of move that the Closer Confidential criteria is designed to produce before the rest of the world catches on. Four blown saves is the headline. But the number underneath it is what concerns us more: his four-seam fastball is posting a .477 wOBA against. His sinker is at .538. Those are not unlucky numbers. Those are contact-quality numbers, and the primer we run this column by says explicitly that declining underlying metrics are a downgrade signal we'd rather act on early than late. The slider is still elite. But he is living dangerously on two of his three pitches, and the grade reflects it.

Louis Varland and Tanner Scott each drop two points, for the same underlying reason: neither of them is in a situation that fully qualifies as "good" by our criteria. The Dodgers used Treinen and Hurt for ninth-inning saves this week with Scott unavailable, and Dave Roberts has confirmed he is not saving Scott exclusively for save opportunities. That is a committee in practice, even if it is not labeled as one. Varland was deployed in the eighth inning while Tyler Rogers took the ninth earlier this week. The Blue Jays do not have a clearly defined closer role. Both arms remain talented. Both grades come down two points each to reflect the situation they are actually in.

Gregory Soto earns a promotion and a mention at the bottom of this section, because the quiet story of Week 10 in Pittsburgh deserves more than a table entry. He earned a win on Friday with a perfect ninth inning as Bryan Reynolds hit the walk-off homer, then came back Saturday to get the final four outs for his seventh save in a wild 10-9 game over the Twins. Two appearances in two days, neither yielding a run. He is now 4-0 with a 1.98 ERA through the season and has been, without much fanfare, one of the more reliable ninth-inning arms in the National League. He moves up to 84.

Riley O'Brien stays put despite the four blown saves on his season ledger, and we are going to explain that decision because this is the kind of call the column's gut component is designed to handle. Four blown saves is a real number. But his ERA, his WHIP, and his underlying contact metrics do not paint the picture of a closer in trouble - they paint the picture of a closer who has had four bad pitches in a season full of otherwise quality outings. He bounced back with two saves this week. The grade holds at 85. We will revisit if the saves total gets worse without the underlying view improving.

Seranthony Domínguez gets a quiet bump to 81. He has been scoreless in his last three outings and the White Sox are not a team that generates much save competition. Small move, earned. I still like Grant Taylor best in this pen, but writers don't make these decisions ...

Seesaw Situations

This is where the spring cleaning got the most unpleasant. We ran every situation in this tier through all six criteria and sent several closers straight to summer school with no diploma and no apology.

The biggest story - and it is not close - is in Detroit. Kenley Jansen is on the IL with pelvic inflammation. Kyle Finnegan, the nominal next man up, left Wednesday's outing against the Mets after warming up in the bullpen with right groin tightness of his own. He was not placed on the IL but his availability is genuinely uncertain. Drew Anderson, who has been used as a tertiary option, was sent out on one day of rest Friday night and blew a save when Miguel Vargas hit a walk-off two-run home run. Every one of the top three arms is either injured, health-questionable, or overworked. Finnegan drops 12 points to 58 under our spring cleaning review. This is the most broken ninth-inning situation in baseball and there is nothing in any of the six criteria - not recent performance, not news, not the underlying view, not the hierarchy, not the team context - that argues for holding him higher. Do not roster anyone in this situation unless your league is very, very deep.

Lucas Erceg drops 12 points as well, and we owe the readers who acted on our enthusiastic endorsement last week a frank acknowledgment: we were wrong, and we are correcting it in full. At Week 9, we wrote "go check right now, I'll wait." Since that endorsement was printed, Erceg has blown a save against the Cardinals with an unearned run that still required him to allow contact in a situation he should have closed. He now has five blown saves on the season, a 5.06 ERA, and a 1.69 WHIP. The Royals are 22-32 and fading. He drops from 79 to 67. The column was early on the optimism and we are early on the reversal. That is the job.

Josh Hader is almost here. The latest word from Houston is that he is expected to be activated in the first week of June - likely available for the Pittsburgh series starting Tuesday. He has made seven rehab appearances and posted a 1.29 ERA with 11 strikeouts across seven innings. The rehab outings that were a mess a few weeks ago have been replaced by a version of Hader that looks very much like the six-time All-Star who dominated this position for years. If you held him, you are about to be rewarded. Bryan King holds at 73 in the interim - a short-term number we expect to retire soon.

Abner Uribe's suspension situation deserves a column mention because it affects the Milwaukee committee in ways that are not fully captured by a grade. Uribe was suspended one game by MLB for his WWE-style crotch chop directed at the Cardinals' dugout Tuesday after an inning-ending strikeout, though he is appealing and currently available to pitch. The committee has shifted toward Trevor Megill as the primary arm, with Uribe's status subject to the appeal. We move Megill to primary in the table and drop Uribe's listing to next option. The grade holds at 79 for the committee.

The Uribe note in the column: He apologized to his teammates, his manager, and Brewers fans. He did not apologize to the Cardinals, citing Cardinals manager Oli Marmol's alleged gestures toward the Brewers' dugout suggesting he was going to order hit batters. Pat Murphy called it unacceptable and said he was embarrassed. Uribe's explanation - "I have my teammates' back, always" - is the kind of thing that gets a reliever fined and earns him a statue in right field at the same time. The column takes no position.

Tony Santillan replaces Graham Ashcraft as Cincinnati's primary entry. Santillan is now the active closer with Ashcraft as next in line. The grade adjusts slightly downward to 75 to reflect the uncertainty in a role that has changed multiple times this season.

Rico Garcia and Anthony Nunez are now explicitly sharing saves in Baltimore while Helsley works his way back. Both have three saves each. Nunez blew a save Monday, which keeps this entry comfortably in Seesaw territory. Garcia remains the primary name but the committee is real and active.

Colorado's situation flipped back toward Juan Mejia at the top of the depth chart, displacing Antonio Senzatela, who we had bumped up last week based on his long-relief usage and solid ERA. This is the Rockies. Do not overthink it.

One More Thing

The Hader return is the most important fantasy baseball event of the next seven days. He has been almost flawless in seven rehab outings, he is the same pitcher who has dominated this role for the better part of a decade, and the fantasy managers who held a roster spot for him all month are about to see that patience rewarded in the form of the best saves rate in the American League. If he is somehow still available in your league at this point - he should not be, but stranger things have happened - this is your last window to add him before the activation is official.

Questions About Closers, Answered

Who are the most secure closers heading into Week 10?

Mason Miller, Cade Smith, David Bednar, Aroldis Chapman, Raisel Iglesias, Jhoan Duran, and Devin Williams all sit at 90 or above - the most Secure closers the column has counted at any single moment in 2026. The top of the market has never looked better. The bottom has rarely looked worse.

Which graduation from Shaky to Secure is most meaningful for fantasy managers?

Jhoan Duran's move is the most impactful because it comes with the largest shift - from 87 to 90 - and carries the most backstory. Ten clean appearances since returning from the oblique IL stint was the threshold we set publicly, and he met it. He is 11-for-11 on the season with a 1.62 ERA and a 1.87 FIP. He is no longer a hold with a question mark. He is a closer.

Should I drop Lucas Erceg or Kyle Finnegan?

Erceg: yes, in all but the deepest formats. Five blown saves, a 5.06 ERA, and a team going nowhere. Finnegan: yes, without hesitation. Jansen on the IL, Finnegan's own groin questionable, and a committee that has now blown saves in consecutive days using three different pitchers. Detroit is the worst ninth-inning situation in baseball and it is not close.

Is the Hader return priced in?

No. Fantasy managers have been cautious about Hader all month because the rehab outings in mid-May were rough. The last seven have not been rough. They have been dominant. His price on the waiver wire reflects the caution, not the current form. Act accordingly.

What should I do with Tanner Scott and Louis Varland?

Hold both, but with open eyes. Scott is still the primary closer in Los Angeles when he is available, and the Dodgers will play a lot of close games in June. Varland is still the primary closer in Toronto by depth chart. But neither is in a situation this column can grade above 84, and fantasy managers who carry both are taking on real volatility for middling reward. If a Secure-tier closer becomes available, one of these two is the logical drop candidate.
