2026 Fantasy Outlook
Diaz was his dominant self in 2025, ranking second among qualified relievers with a 1.63 ERA and 38% strikeout rate, while tying for fifth with a 0.87 WHIP. Perhaps his most impressive highlight was an absurd 33-game stretch during which he permitted only 1 ER, posting a 0.27 ERA, 0.80 WHIP and 50:11 K:BB across 33.2 innings. Diaz didn't produce as many saves (T-11th) as some of the other full-time closers - he was limited to just five over the final two months as New York crumbled down the stretch - but his stability in the role was among the highest in the league. Given his outstanding performance, the right-hander declined his $18.5M option for 2026, which would have been a $3M pay cut compared to what he earned last year. The Mets extended a 1-year, $22.05M qualifying offer to Diaz, which the 2025 NL Reliever of the Year is expected to decline in favor of a multi-year contract. On average, the 31-year-old has been the second closer off the board in early 2026 drafts. Read Past Outlooks

Diaz rejected the Mets' one-year, $22.025 million qualifying offer Tuesday, Alden Gonzalez of ESPN.com reports.
Analysis
Diaz opted out of the two years and $38 million remaining on his contract with the Mets earlier this month, and now he has passed on the qualifying offer. Neither decision was a surprise, as the closer shouldn't have difficulty netting a big multi-year pact this winter. If he leaves the Mets, New York will receive a draft pick as compensation.

Diaz returned to action last season after missing all of 2023 due to a torn ACL. The right-hander didn't pitch at the level of his remarkable 2022 campaign, but his 38.9 percent strikeout rate ranked 2nd among relief pitchers and was right in line with his career average (40.1 percent). Diaz only posted 20 saves, but he missed some time near midseason (shoulder injury, 10-game suspension) and finished most of the games he appeared in when healthy. He worked through a rough patch in May and had notable home (1.74 ERA) and road (5.96 ERA) splits, but his stability as the Mets closer was never in question. On average, the 31-year-old has been selected as the third closer off the board in early 2025 drafts. He warrants an early pick thanks to his 30-save and 100-strikeout upside.
Diaz missed all of last season after suffering a complete tear of his right patellar tendon while celebrating during the World Baseball Classic last March. The veteran closer threw several bullpen sessions towards the end of last season, but the Mets didn't rush him back since they weren't in playoff contention. The last we saw Diaz pitch in the majors, he struck out 118 batters over 62 innings for a strikeout rate north of 50%, but achieving those types of numbers again will depend on several factors. The obvious one is health, while the other two are Diaz's velocity and effectiveness of his slider. The slider didn't play well during his "down" season in 2019 and his ratios suffered. However, if the soon-to-be 30-year-old is throwing triple-digit heaters and wiping hitters out with the slider - look out. Monitor Diaz during spring training, but don't wait to long in the draft room to click his name, as he'll be among the top 3 closers off board soon enough.
Diaz made the best of a contract year, as no relief pitcher in 2022 came close to his 50.2% strikeout rate, 25.2% SwStr%, 17.1 K/9 or 42.6% K-BB%. His 1.31 ERA ranked fourth among qualified relievers, while his 0.90 FIP and 1.11 SIERA were also the best in the league. Diaz's name was scattered across many Statcast leaderboards, as he posted a 99th percentile rating, or better, in multiple pitching metrics. However, he was "merely" league average in HardHit% and BB%. One main reason why Diaz was so good last season can be attributed to a pitch mix change. He threw his fastball far less often - a roughly 20% difference from his most recent seasons - while using his slider as his primary offering (58% pitch usage) for the first time in his career. Diaz allowed just 17 hits - 16 of which were singles - on his slider for a .114 BA on the pitch. Expect the soon-to-be 29-year-old to be among the top two closers drafted in 2023 now that the Mets re-signed him for 5 years at $102 million.
Diaz was the highest-leveraged reliever in baseball as measured by gmLI, which measures a pitcher's average Leverage Index upon entering a game. He rarely gave up hard contact, as his 21.3% hard hit percentage was fifth-best among qualified relievers and in the 99th percentile. This was a vast improvement over his 48.1% hard hit percentage in 2019, which was third-worst. Diaz was 32-for-38 in save chances with a 3.45 ERA (2.84 SIERA) and 1.05 WHIP over 62.2 innings. He averaged a career best 98.8 mph on his fastball, though his slider carried a .119 XBA and .164 XSLG as his put-away pitch. Most importantly, Diaz maintained his ability to miss bats with a 12.8 K/9 and 16.5% SwStr%. The soon-to-be 28-year-old is entering his final year of arbitration before he becomes a free agent in 2023. He's poised to close another season for the Mets and be drafted among the top 10 options for saves.
Diaz's 2019 campaign, which saw his ERA spike from 1.96 to 5.59, served as a valuable reminder that even the best relievers in baseball aren't particularly reliable from season to season. The righty looked like he was in line for another disappointing season at the start of last year, when he allowed runs in two of his first three appearances. He allowed just three total earned runs the rest of the way, however, finishing the year with a stellar 1.75 ERA, a number he backed up with a career-high 45.5 K%. It wasn't all positive for his fantasy profile, however, as his early struggles combined with his poor 2019 season meant he was removed from the closer role for most of the year and wound up finishing with just six saves. While he may not have his manager's full faith heading into 2021, he's clearly closer material most of the time, making him a risky but very high-ceiling option during draft season.
Diaz struck out 39% of the hitters he faced in 2019 and had a 30 K-BB%, both of which are elite rates for any relief pitcher. The problem was what happened with the other 61% of hitters he faced last season. Despite having both velocity and a strikeout rate in the 99th percentile last season, Diaz was in the second percentile of hard-hit rate and the 11th percentile of exit velocity by batters. Those type of outcomes are what drove his .281 BABIP from his record-breaking 2018 season up to .377 this past season. Both his fastball and slider had negative run values for the first time in his career, and that mainly came from his inconsistent command of both pitches. Diaz's struggles were a great reminder of two things: reliever volatility, and the difference between command and control. He threw strikes, but not where they needed to be. Elite seasons are often followed up by steps backward. Jump back in on Diaz.
Diaz ended 2018 as the top closer and looks to be one of the first off the board in 2019 after an offseason trade to the Mets. Here's the thing: amassing another 61 save chances with 57 conversions is a long shot. Last year, Diaz tied for the second-most saves in history. Even with comparable skills, 15-20 fewer is a fair expectation. Speaking of skills, they're elite. His 18.9 SwStr% was bested by only Josh Hader, and just barely at that. His K-BB% was tops in the league. Diaz throws a 98-mph fastball almost two-thirds of the time, complemented by a 90-mph slider. There's really nothing to point to in terms of luck as Diaz's BABIP, HR/FB and LOB% were all within expected ranges. The skills, hence strikeouts and ratios, are real and repeatable and thus worthy of chasing aggressively. Just don't count on another 50-save season.
The road was a bit rocky for Diaz in 2017, with the Mariners temporarily relieving him of closer duties on a couple occasions, but when it was all said and done Diaz tied for fourth in the American League in saves. He converted 21 of 23 save opportunities in the second half and struck out 32 percent of the batters he faced overall using a combination of high-90s fastballs and high-80s sliders. Diaz can be his own worst enemy with the walks, and the uptick in home runs last season is a concern, although he was better in that regard down the stretch (two homers allowed in his final 30.1 innings). His stuff is electric most of the time and there aren't any proven options behind him in the Seattle bullpen, so Diaz should be given every chance to remain in the closer role throughout 2018. However, he's not exactly a "safe" investment given the slip in performance from 2016 and the general year-to-year unpredictability of major-league relievers.
Seattle's save chances were dominated in the first half by Steve Cishek. However, after Cishek landed on the disabled list, Diaz, once a top starting pitching prospect, took the reins and never looked back. He dazzled in the bullpen over the final two-plus months, going 18-for-21 in save chances. Diaz ranked sixth in second-half K/9 (14.3) among arms with 20-plus appearances, behind Ken Giles, Kenley Jansen, Dellin Betances, Craig Kimbrel and Aroldis Chapman. On the season, he finished fourth among relievers with an 18.5 swinging-strike percentage. While his his walk rate was a sparkling 2.6 BB/9, he has bouts of inefficiency and must aim to get ahead in more at-bats. Still, the right-hander, who turns 23 in March, boasts outstanding peripherals (33.6 K-BB%) and electric stuff. Even with some correction perhaps coming, Diaz could deliver numbers befitting a top-five fantasy closer at a discount relative to bigger names.
It is a sad state of affairs when a pitcher who finished the previous season with a 4.57 ERA in 104.1 innings at Double-A has a claim as the best prospect in a farm system, but that is where the Mariners are at. Diaz is not nearly as bad as that ERA suggests — he had a 1.70 ERA in 37 innings at High-A Bakersfield before his promotion and his 3.22 FIP at Double-A Jackson suggests he was pretty unlucky in Southern League play. His 145:46 K:BB in 141.1 innings illustrates his potential to be an average or better bat misser with an average command profile in the big leagues, essentially serving as a true No. 3 starter who should benefit from playing half his games in Safeco Field. Diaz should spend most, if not all of his age-22 season at Triple-A Tacoma, potentially getting some late-season spot starts with the Mariners, but more likely figuring into the rotation plans in 2017.
A third-round pick out of Puerto Rico in the 2012 draft, Diaz held his own at Low-A Clinton last year as a 20-year-old after dominating in rookie ball in 2013. He has a low-to-mid-90s fastball, a good slider, and a developing changeup. His control needs some work, but he has plenty of time to hone those skills. He will also continue to fill out. His 6-foot-2, 178-pound frame is about 20 pounds more than his draft weight, but he's bound to get bigger and stronger still. The organization's co-starting pitcher of the year in 2014 (along with Jordan Pries), Diaz is a ways away, but he has plenty of upside and is worth keeping an eye on.

PFree Agent  
November 14, 2025
The Blue Jays met with Diaz's agents at the general managers' meetings, Ken Rosenthal of The Athletic reports.
Analysis
The Blue Jays are known to be shopping for late-inning relief help, so it's no surprise they would touch base with Diaz's agents. It's not clear at this point how high up Diaz is on Toronto's wish list, but the club has said it's open to moving Jeff Hoffman to a setup role if it can land a marquee ninth-inning weapon. Diaz would certainly qualify, having posted a 1.63 ERA and 38 percent strikeout rate for the Mets in 2025.
