Hader was born in Millersville, Maryland, to Tom and Patricia Hader. He attended Old Mill High School in his hometown, where he emerged as a standout baseball player. During his senior year at Old Mill High School, Hader compiled an impressive 10-0 win-loss record with a remarkable 0.30 earned run average and 125 strikeouts. He also contributed at the plate, maintaining a batting average above .400 while hitting four home runs. After graduating from high school, Hader initially prepared to enroll at Anne Arundel Community College before beginning his professional baseball career.
Hader worked extensively on his mechanics and endurance during his formative years. His dedication to improvement laid the foundation for the significant velocity gains he would later achieve as a professional pitcher. The work ethic and competitive drive he developed during these early years would later distinguish him among professional pitchers.
Path to Major League Baseball
The Baltimore Orioles selected Hader in the 19th round of the 2012 MLB draft with the 582nd overall selection. He signed with the Orioles for a $40,000 signing bonus rather than attend Anne Arundel Community College. Beginning his professional career, Hader played for the Gulf Coast Orioles and the Aberdeen Ironbirds of the Single-A New York-Penn League. He allowed only 14 hits and nine walks while striking out 48 batters in 28 and two-thirds innings during his debut professional season.
The Houston Astros acquired Hader on July 31, 2013, when the Orioles traded him along with L. J. Hoes to Houston in exchange for Bud Norris. His development accelerated with the Astros organization, as he played for the Quad Cities River Bandits and the Lancaster JetHawks of the High-A California League. In 2014, Hader combined with two other pitchers to throw a no-hitter on May 13. That same year, he was named California League Pitcher of the Year after posting a 9-2 record with a league-leading 2.70 earned run average and 112 strikeouts over 103 and one-third innings. In 2015, Hader was selected to play for the United States national baseball team at the Pan American Games in Toronto before the Astros traded him to the Milwaukee Brewers organization.
Joshua Ronald Hader Career
Milwaukee Brewers Breakthrough (2017-2022)
Hader made his major league debut with the Brewers on June 10, 2017, after being promoted from the Colorado Springs Sky Sox of the Triple-A Pacific Coast League. His 2018 season marked a breakthrough, as he posted a 6-1 record with 12 saves and a 2.43 earned run average while striking out 143 batters in 81 and one-third innings. His dominance against left-handed hitters was particularly striking, as he held them to a .088 batting average, the lowest among qualified pitchers. Hader earned his first All-Star selection that season and was named National League Reliever of the Year, becoming the first non-full-time closer to win the award.
The 2019 season saw Hader emerge as the Brewers’ primary closer following injuries to Jeremy Jeffress and Corey Knebel. On March 30, he pitched an immaculate inning against the St. Louis Cardinals, striking out Tyler O’Neill, Dexter Fowler, and Yairo Munoz on nine consecutive strikes. Hader collected NL Reliever of the Month honors for both May and June in 2019 before finishing the season with a 3-5 record, a 2.62 earned run average, and 138 strikeouts in 72 and two-thirds relief innings. He earned his second consecutive Reliever of the Year award that year. In 2020, Hader opened the season with an unprecedented streak of 12 consecutive hitless appearances, the longest such streak in major league history. He finished the season leading the National League with 13 saves in 15 opportunities despite a 3.79 earned run average.
The 2021 season proved to be historic for Hader. On May 8, he became the fastest pitcher in major league history to reach 400 strikeouts, accomplishing the feat in just 234 and two-thirds innings, breaking Craig Kimbrel’s previous record of 236 innings. For July, he was named NL Reliever of the Month for the fourth time in his career. On September 11, 2021, Hader pitched the ninth inning to close out a combined no-hitter against the Cleveland Indians. He finished the season with a career-low 1.23 earned run average, 34 saves in 35 chances, and 102 strikeouts in 58 and two-thirds innings, earning him his third Reliever of the Year award.
San Diego Padres (2022-2023)
After beginning the 2022 season with 25 saves in 27 appearances and an outstanding 1.05 earned run average, Hader experienced a decline in performance during the summer months. On August 1, the Brewers traded him to the San Diego Padres in exchange for Taylor Rogers, Dinelson Lamet, Esteury Ruiz, and Robert Gasser. He made his Padres debut the following day, earning the win against the Colorado Rockies. However, his struggles continued through mid-August, with his earned run average rising to 6.52. The Padres announced they would use a closer committee to give Hader a break from save opportunities. He rebounded strongly in September and played an instrumental role in the Padres’ postseason run.
On January 13, 2023, Hader signed a one-year, $14.1 million contract with the Padres, avoiding salary arbitration. He was named National League Reliever of the Month for April after recording 10 saves while holding opposing batters to a .093 batting average and allowing only one run in 13 innings pitched. Following the 2023 season, Hader became a free agent.
Houston Astros Era (2024-Present)
On January 22, 2024, Hader signed a five-year, $95 million contract with the Houston Astros. He earned his first win as an Astro on April 30, making his first two-inning appearance since 2019 and his first appearance of at least four outs since August 14, 2020. On August 10, 2024, against the Boston Red Sox, Hader converted his 25th consecutive save opportunity, surpassing Brad Lidge’s franchise record of 24, and ultimately extended that streak to 29 total saves. For the month of August, he surrendered only one earned run over 13 and one-third innings with a 0.68 earned run average and was named American League Reliever of the Month, his seventh career monthly award.
On September 13, 2024, Hader recorded his 30th save while helping the Astros achieve their 5,000th franchise win by defeating the Los Angeles Angels 5-3. He finished the 2024 season with 71 regular season appearances, an 8-8 record, a 3.80 earned run average, 34 saves, and 105 strikeouts in 71 innings. He ranked ninth in the American League in appearances and second in both games finished and saves.
Pitching Style and Strengths
Hader features a mid-to-high 90s fastball that has become his signature offering. His strikeout ability stands as his greatest weapon, as evidenced by his record-setting pace to 400 career strikeouts and his consistent ability to record more than a strikeout per inning throughout his career. His dominance against left-handed batters, including a historically low .088 batting average against them in 2018, showcases his ability to retire hitters from both sides of the plate. Hader has demonstrated the capacity to pitch multiple innings when needed and excels in high-pressure situations, making him a reliable option for closing duties.
Notable Events and Milestones

His 2018 All-Star selection came amid controversy following the discovery of problematic social media posts from his past, yet he still appeared in the game and performed. His 2021 combined no-hitter stands as a career highlight, as does his record-setting 400th strikeout, achieved faster than any pitcher in major league history. With the Astros in 2024, he broke Brad Lidge’s franchise record with 29 consecutive saves and reached the 200-career save milestone on Opening Day 2025.

2025 Season Performance
The 2025 season began with a milestone achievement for Hader as he recorded his 200th career save on Opening Day against the New York Mets at Minute Maid Park.
