Pitcher Josh Hader was a 19th-round pick of the Baltimore Orioles in the 2012 amateur draft, out of a high school in nearby Millersville, MD. The scout was Dean Albany. Signing shortly after having been drafted, he went 2-0, 1.88 with two saves in 17 relief outings between the GCL Orioles and Aberdeen IronBirds, striking out 48 batters in 28 2/3 innings. He was converted to starting in 2013 and pitched well for the Delmarva Shorebirds of the South Atlantic League in spite of a 3-6 record in 17 starts. His ERA was a solid 2.65 in 85 innings, with 79 strikeouts. On July 31st, he was traded to the Houston Astros, alongside OF L.J. Hoes, in return for P Bud Norris.
Pitching for the Lancaster JetHawks on May 13, 2014, Hader combined with two relievers on a 1-0 no-hitter against the Bakersfield Blaze; he pitched six hitless frames before turning the ball to J.D. Osborne, who went two innings, and Daniel Minor, who earned the save with a perfect 9th inning. Hader went 9-2, 2.71 in 22 games for Lancaster, very nice numbers in light of Lancaster's status as perhaps the best hitting environment in the minor leagues. He was promoted to the Corpus Christi Hooks of the AA Texas League late in the season, going 1-1 in 5 starts to finish with a combined record of 10-3, 3.29 in 27 games, 19 of them starts. He pitched 103 inning and struck out 112 opponents. After the season, he was named the California League's Pitcher of the year for his work at Lancaster.
He was back with Corpus Christi at the start of 2015 and was 3-3, 3.17 in 17 games, including 10 starts. On July 30th, the Astros traded Hader and three other prospects, Brett Phillips, Adrian Houser, and Domingo Santana, to the Milwaukee Brewers for OF Carlos Gomez and P Mike Fiers. The Astros also acquired slot No. 76 in the 2015-16 international pool. He finished the year with the Biloxi Shuckers of the Southern League, where he went1-4, 2.79 in 7 starts. He was at Biloxi again at the start of 2016 and went2-1, 0.95 in 11 starts to earn a promotion to the AAA Colorado Springs SkySox. He found the going tougher there, as he was just 1-7, 5.22 in 14 starts,
In 2017, Hader made it to the big leagues in June after making 12 starts at Colorado Springs, where the results were again unspectacular: 3-4, 5.37 in 12 starts. The Brewers used him as a reliever, however, with outstanding returns: in 35 games his ERA was just 2.08, and he struck out 68 batters in 47 2/3 innings, while allowing just 25 hits. He went 2-3 and formed an outstanding bullpen tandem with closer Corey Knebel as Milwaukee made an unexpected run at the postseason, falling just short. He was named to the 2017 Topps All-Star Rookie Team after the season.
In 2018, Knebel went down with an injury after only a few games, and after veteran Matt Albers struggled in trying to take over as the closer, Hader got his first chance to save a game against the New York Mets on April 14th; the Mets had won 9 straight games, but were trailing the Brewers 4-1 in the bottom of the 8th when Hader entered the game and proceeded to strike out the next five batters in order before inducing Jay Bruce to fly out harmlessly to end the game. He had another equally impressive two-inning save on April 17th in a 2-0 win over the Cincinnati Reds. At that early point of the season, he had struck out 25 of the 41 batters he had faced; he was in the top 10 in the National League for strikeouts even though he had pitched just 11 2/3 innings! On April 30th, he had another tremendous performance to record a save, again against the Reds: he replaced Brandon Woodruff with one out in the 7th and faced 9 batters, retiring 8 of them on strikeouts, the only blemish being a five-pitch walk to Tucker Barnhart with one out in the 8th. That earned him another save in a 6-5 win. He needed just 37 pitches to accomplish this, or an average of just over four per batter! No pitcher since 1900 had ever struck out 8 batters in fewer than three innings. He finished May with 66 strikeouts, the most by a reliever before June as per Elias Sports Bureau; Scott Williamson (65 in 2000) had held the record previously. He cooled down slightly after that, with an ERA of 2.00 in June and 2.84 in the first half of July to finish the first half at 1.50 with 89 Ks in 48 innings. He was named to the All-Star team for the first time but struggled in the game, giving up a three-run homer to pinch-hitter Jean Segura, one of four hits in just a third of a inning before giving way to Brad Hand. However, with the greater scrutiny placed on him due to his emerging celebrity, light was placed on tweets he had sent out as a 17-year-old, containing highly offensive racist, misogynistic and homophobic language. He had to apologize after the game and explained that he was highly immature and stupid at the time. He was ordered by Major League Baseball to undergo sensitivity training and take part in its diversity and inclusion initiatives. The Brewers also took steps to distance themselves from his comments and to underline how seriously they were taking the matter. A meeting was set up with MLB Vice-President Billy Bean, GM David Stearns and manager Craig Counsell, followed by a meeting with teammates.
In spite of that hiccup at the All-Star game, Hader continued to pitch extremely well for the Brewers. He finished the season with a record of 6-1, 2.43 and 12 saves in 55 games. He logged 81 1/3 innings and struck out 143 batters (against 30 walks), the most strikeouts in a major league history by a left-handed reliever. He was named the recipient of the Trevor Hoffman Award as the best reliever in the National League. In the postseason, he did not allow any runs in 10 innings over 7 appearances, being a major reason why the Brewers made it to the threshold of a World Series appearance, only being eliminated by losing Game 7 of the NLCS against the Los Angeles Dodgers.
