2021 Fantasy Outlook
Hader was literally unhittable to start last season, as he did not allow even one hit over his first 12 appearances. The wheels came off a bit after that, though, and he finished with easily the worst ERA of his career. He still struck out batters with the best of them, averaging over 14 K/9, and recorded 13 saves in just 21 appearances. Hader's fastball remains puzzling, and he threw his slider more last season after having issues with the long-ball the year before. Hader remains an elite late-inning option, but he is getting pricey; and with Devin Williams in tow, the Brewers could elect to trade Hader over the offseason to restock their farm system. He would presumably be the favorite to close wherever he finds himself come Opening Day, but he would be a dominant co-closer or eighth-inning man as well. Read Past Outlooks

Closes out win for 34th save
PMilwaukee Brewers
September 25, 2021
Hader walked one and struck out one in a scoreless inning to earn the save in Saturday's 2-1 win over the Mets.
ANALYSIS
Few relievers have pitched better than Hader this year, and he's been nearly untouchable with a 17.1-inning scoreless streak dating back to the start of August. In that span, he's allowed six hits and 10 walks while striking out 29. For the season, the southpaw is 34-for-35 in save chances with a 1.29 ERA, 0.86 WHIP and 94:24 K:BB across 55.2 innings.

2014
Hader seemed destined to reprise the versatile late-inning role he occupied in 2018, but when both Corey Knebel and Jeremy Jeffress were injured in the spring he was needed to close games. Hader did that about as well as anybody, picking up more saves in 2019 than just two pitchers. He had some issues with the long ball, but he also improved his K:BB and posted minuscule ratios for the third straight year. In most cases those numbers would make Hader a lock to close, but it could be argued he is more valuable pitching in several situations instead of just one, and manager Craig Counsell could use him as such and let Knebel be the primary closer. Hader strikes out batters at a historic pace, using mainly a fastball that comes in from an angle that baffles hitters. That alone makes him an elite relief option, and he should be treated as a top closer even if he isn't getting all the saves for the Brewers.
Hader developed into the best left-handed reliever in the game, and was a huge boon for fantasy owners, putting up useful numbers in the five standard roto categories and elite numbers in some. His 46.7 K% led qualified relievers by a notable margin (Edwin Diaz ranked second at 44.3%). Calls for Hader to be stretched out as a starter need to end -- he is extremely valuable in his current role and threw his fastball 79.5% of the time while utilizing his slider 20.3% of the time. It is not a starter's pitch mix, and he is at his best when throwing max effort. The real question when it comes to fantasy roster building is how many saves we can expect from Hader. Corey Knebel and Jeremy Jeffress are very capable in the ninth inning, so while Hader will undoubtedly be left in to close a couple games per month, he shouldn't be expected to top last year's total. "Finding the next Josh Hader" is a far better movie title than an expectation. Draft the real thing.
Hader entered last season as arguably the top left-handed starting pitching prospect in the game, but he got off to a slow start at the Triple-A level as he struggled to harness his electric stuff. While he was not ready to join the starting rotation in 2017, the Brewers did decide he was good enough to pitch out of the bullpen and called him up as a reliever in June. The move turned out to be a stroke of genius, as he overpowered opposing hitters, particularly of the left-handed variety, who combined to hit .140 while posting just one extra-base hit against Hader. It’s almost certain he won’t be able to pitch in the same manner as last year, when he mainly needed only his mid-90s fastball to get opponents out, but his slider can be devastating as well. The Brewers will at least consider using Hader as a starter again, but his stuff may not play as well in that role, and the team could decide he is plenty useful as one of the best left-handed relievers in the league. That could maximize his value for the 2018 Brewers, but would also put a cap on his fantasy upside.
Hader has rocketed through the upper levels of the minors over the past two seasons, rising from High-A in 2014 to Triple-A in 2016 -- he was even considered for a spot start with the Brewers late in the season, but it never came to fruition. The lanky lefty struck out a ludicrous 161 batters over just 126 innings across Double-A and Triple-A, proving his pitches aren't only capable of fooling the raw youngsters of the lower minors. There are still questions surrounding the quality of his changeup and command, and at 6-foot-3 and 185 pounds, many of the same concerns that surrounded Chris Sale's future durability as a young prospect have resurfaced with Hader. Despite those worries, Hader's prospect stock has ballooned over the past two seasons as he has turned into one of the gems of the Brewers' restocked farm system. He should finally be allowed to test out his plus fastball and plus slider against big league hitters sometime this summer.
A 19th-round pick in 2012, Hader was barely on the prospect radar before the Brewers acquired him as part of last summer's Carlos Gomez trade. Hader was sharp in Double-A, as he posted a 3.03 ERA in 104 innings between the Brewers and Astros systems, but he really shined in the Arizona Fall League, where had one of the best performances of any pitcher, posting a 0.56 ERA with 19 strikeouts in 16 innings. Hader has an unorthodox delivery and there are questions about his durability, but he has shown huge upside over the past calendar year or so and he's now one of the top prospects in the Brewers' system. Beginning the 2016 season as a 22-year-old, Hader will probably start in Triple-A. The Brewers have a glut of fringey starters right now, so a lot would have to happen for Hader to arrive in the major leagues in 2016, with mid-2017 seeming like a better estimated time of arrival.
Acquired from Baltimore in the 2013 Bud Norris trade, Hader earned a promotion to Double-A last season as a 20-year-old after posting outstanding numbers in the hitter-friendly California League. In 22 games (15 starts) with High-A Lancaster, the 6-foot-3, 160-pound lefty went 9-2 with a 2.70 ERA, 1.11 WHIP and 112:38 K:BB over 103.1 innings. While his big league future as a starter or long man out of the bullpen remains unclear due to his skinny frame and potential for breaking down deeper in outings, how Hader performs this season -- likely in Double-A with a potential promotion to Triple-A if things go well -- should better determine his path to the majors.
Hader, a 19-year-old left-handed starter, was acquired by the Astros in the trade that sent Bud Norris to Baltimore. Between both clubs, he accumulated 22 starts in Low-A ball, posting a 2.77 ERA with a 95:54 K:BB ratio over 107.1 innings while earning South Atlantic League All-Star honors. Hader needs to work on the command of his three pitches - a low-90s fastball, changeup and curve - but he has plenty of time to do that as he grows into his 6-foot-3, 160-pound frame. He has the stuff to advance quickly through the Astros' system, but he's likely a few seasons away from contributing in Houston.
