2020 Fantasy Outlook

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. Read Past Outlooks

Notches sixth save

PNew York Mets

September 24, 2020

Diaz gave up a run on two hits in the ninth inning Thursday against the Nationals but escaped with his sixth save of the season. He struck out one batter.

ANALYSIS
Diaz's streak of consecutive scoreless appearances ended at 10, but he eventually shut the door, making him 4-for-4 in save chances this month. The right-hander has a sparkling 1.80 ERA overall this season, though he lost the closer role for a while early on and it took Seth Lugo returning to the rotation for him to get it back. Diaz faces an uncertain future with the organization.

Stat Review

How does Edwin Diaz compare to other relievers?

This section compares his stats with all relief pitcher seasons from the previous three seasons (minimum 30 innings)*. The bar represents the player's percentile rank. For example, if the bar is halfway across, then the player falls into the 50th percentile for that stat and it would be considered average.

* Exit Velocity, Barrels/BBE %, Balls Hit 95+ MPH %, and Spin Rate are benchmarked against 2019 data (min 30 IP). See here for more exit velocity/barrels stats plus an explanation of current limitations with that data set.

Past Fantasy Outlooks

2019

2018

2017

2016

2015

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.
