The Baltimore Orioles selected Hader in the 19th round of the 2012 MLB draft, with the 582nd overall selection.[3][4] He signed with the Orioles for a $40,000 signing bonus, rather than attend Anne Arundel.[1][3] Beginning his professional career, Hader's fastball velocity increased, from 84–88 miles per hour (135–142 km/h) as a high school player, to 94–95 miles per hour (151–153 km/h) as he changed his workout routine.[5]
Hader began the 2017 season with Colorado Springs. The Brewers promoted him to the major leagues on June 9.[17] He made his major league debut on June 10.[18]
Hader began 2018 in the Milwaukee bullpen. On April 30, Hader became the first pitcher ever to record eight strikeouts in an outing that was less than three innings long. He recorded a 2+2⁄3-inning save against the Cincinnati Reds, in which he faced nine batters, recording eight strikeouts and one walk.[19] Owning a 1.21 ERA with 83 strikeouts in 44 innings, Hader was named to the 2018 MLB All-Star Game.[20] Hader appeared in the 2018 All-Star Game at the top of the eighth inning. During his appearance, he gave up hits to Rangers'Shin-Soo Choo and Astros' George Springer before Mariners'Jean Segura hit a home run to left field to give the American All-Stars a 5–2 lead.[21][22] After giving up a single to Boston Red Sox baseman Mitch Moreland, Hader was replaced after 26 pitches, allowing four hits and one out over five batters.[23]
Hader during a game in 2019
In 2018, Hader was 6–1 with 12 saves and a 2.43 ERA. He had 143 strikeouts in 81+1⁄3 innings. Among MLB pitchers who threw at least 20 innings, Hader held left-handed batters to the lowest batting average (.088).[24] He won the National League Reliever of the Year Award,[25] becoming the first non-full-time closer to win the award.
Hader began the 2019 season as the Brewers' closer following injuries to fellow relievers Jeremy Jeffress (shoulder strain) and Corey Knebel (Tommy John surgery). On March 30, Hader pitched an immaculate inning to earn the save against the St. Louis Cardinals, striking out Tyler O'Neill, Dexter Fowler, and Yairo Munoz on nine consecutive strikes, seven of which were swinging strikes.[26] Hader received the NL Reliever of the Month Award for both May and June.[27] In the 2019 National League Wild Card Game, Hader blew the save for the Brewers, giving up a three-run single to Juan Soto of the Washington Nationals, which, coupled with an error from right fielder Trent Grisham, led to Washington's go-ahead run scoring on the play and resulted in the Brewers eventually losing the game.[28] Hader finished his 2019 season with a 3–5 record, a 2.62 ERA, and 138 strikeouts over 72+2⁄3 relief innings. He won his second consecutive NL Reliever of the Year Award.[29]
Hader began the 2020 season with 12 consecutive hitless appearances, the longest such streak in major league history.[30] Hader finished the season with a 3.79 ERA and an NL-leading 13 saves in 15 chances.
On May 8, 2021, Hader reached 400 strikeouts faster than any other pitcher in MLB history, doing so in 234+2⁄3 innings pitched, breaking the prior record of 236 innings, which had been set by Craig Kimbrel in 2014.[31] For July, Hader was named NL Reliever of the Month, the fourth time he won the award.[32] On September 11, Hader pitched the ninth inning to close out a combined no-hitter against the Cleveland Indians. [33] He finished the 2021 season with 34 saves in 35 opportunities; he recorded a career-low 1.23 ERA with 102 strikeouts in 58+2⁄3 innings.
After beginning the 2022 season with 25 saves in 27 appearances and a 1.05 ERA, Hader’s pitching declined during the summer, and on August 1, the Brewers traded him to the San Diego Padres for Taylor Rogers, Dinelson Lamet, Esteury Ruiz, and Robert Gasser.[34] He made his Padres debut the following day, earning the win against the Colorado Rockies.[35] However, his struggles continued, including a stretch of earning only two saves in 13 appearances, with an increased ERA of 6.52. On August 20, the Padres announced that they would use a closer committee to give Hader a 'little break' from save chances.[36] He regained his all-star form in September, and was instrumental in the Padres' postseason run.[37]
On January 13, 2023, Hader signed a one-year, $14.1 million contract with the Padres, avoiding salary arbitration.[38] Hader was named the NL Reliever of the Month for April after recording 10 saves and holding opposing batters to an .093 batting average while allowing only one run in 13.0 innings pitched.[39] He became a free agent following the season.
