Josh Hader Bio
Joshua Ronald Hader, born on April 7, 1994, in Millersville, Maryland, is an American professional baseball pitcher for the Houston Astros of Major League Baseball. A left-handed reliever, Hader has built a reputation as one of the most dominant closers of his era, earning six All-Star selections and three National League Reliever of the Year Awards. He has also pitched in the All-Star Futures Game and represented the United States in international competition.
Over the course of his MLB career, Hader has suited up for the Milwaukee Brewers, the San Diego Padres, and the Houston Astros. He set a major league record in 2021 as the fastest pitcher to reach 400 strikeouts, doing so in fewer innings than any pitcher before him. In 2024, he signed a five-year, $95 million contract with the Astros, establishing himself as one of the highest-paid relievers in baseball.
Early Life and Background
Joshua Ronald Hader grew up in Millersville, Maryland, where he attended Old Mill High School and played for the school’s baseball team. As a senior, he posted a perfect 10–0 win–loss record with a 0.30 earned run average and 125 strikeouts, while also batting above .400 with four home runs. His performance on the mound and at the plate made him one of the most sought-after prep pitchers in the region.
After graduating, Hader planned to enroll at Anne Arundel Community College, but his professional plans changed quickly. The Baltimore Orioles selected him in the 19th round of the 2012 MLB draft, and he chose to begin his pro career rather than attend college. He signed with the Orioles for a $40,000 signing bonus, marking the official start of his journey through professional baseball.
Off the field, Hader was raised in a close family environment. He is the son of Tom Hader and Patricia Hader, who supported his early athletic development. Their encouragement helped shape his work ethic and competitive drive during his formative years in Maryland.
Path to Professional Baseball
Hader’s path to the majors began in the Orioles’ farm system, where he sharpened his skills in the rookie-level Gulf Coast League and the Low-A New York–Penn League. His fastball velocity jumped significantly after high school, climbing from the mid-80s to the mid-90s as he adjusted his workout routine. In 2013, he reached the Single-A South Atlantic League and appeared in the league’s All-Star Game, signaling his emergence as a top pitching prospect.
On July 31, 2013, the Orioles traded Hader to the Houston Astros as part of a deal for pitcher Bud Norris. The Astros assigned him to the Quad Cities River Bandits to finish the 2013 season. The following year, pitching for the High-A Lancaster JetHawks, Hader helped combine on a no-hitter and earned California League Pitcher of the Year honors after leading the league with a 2.70 ERA.
His momentum carried into 2015, when he was selected to represent the United States in the Pan American Games in Toronto. Later that summer, on July 30, 2015, the Astros traded Hader to the Milwaukee Brewers as part of a multi-player package. The trade placed him in a new organization that would soon bring him to the major leagues.

Early Career (2015–2017)
After joining the Brewers, Hader was assigned to the Double-A Biloxi Shuckers of the Southern League, where he finished the 2015 season with a 3.03 ERA. The Brewers invited him to big-league spring training in 2016, and he opened that year back in Biloxi before making his Triple-A debut with the Colorado Springs Sky Sox in June.

He made his MLB debut the following day, launching what would become one of the most successful relief careers of his generation. By the end of the year, he had established himself as a high-leverage option out of the Milwaukee bullpen.
Milwaukee Brewers Breakthrough (2017–2022)
Hader quickly became one of baseball’s most talked-about relievers. On April 30, 2018, he became the first pitcher in major league history to record eight strikeouts in an outing shorter than three innings, fanning eight of the nine batters he faced against the Cincinnati Reds. He earned a trip to the 2018 MLB All-Star Game and finished the year 6–1 with 12 saves and a 2.43 ERA, holding left-handed batters to a league-low .088 average. That performance earned him the National League Reliever of the Year Award, making him the first non-full-time closer to win the honor.
In 2019, Hader opened the season by pitching an immaculate inning against the St. Louis Cardinals, striking out the side on nine pitches. He picked up his second consecutive NL Reliever of the Year Award and finished 3–5 with a 2.62 ERA and 138 strikeouts. He opened the 2020 season with 12 consecutive hitless appearances, the longest such streak in major league history, and led the National League with 13 saves. On May 8, 2021, Hader set another record by reaching 400 strikeouts faster than any pitcher in MLB history, doing so in 234⅔ innings. He closed out a combined no-hitter against the Cleveland Indians on September 11 and finished the year with a career-low 1.23 ERA and 34 saves.
San Diego Padres Era (2022–2023)
Hader opened 2022 with the Brewers, going 25-for-27 in save opportunities with a 1.05 ERA before the trade deadline. On August 1, 2022, Milwaukee sent him to the San Diego Padres in a multi-player deal. He debuted for San Diego the next day and picked up a win against the Colorado Rockies. After a mid-summer slump, the Padres briefly shifted to a closer committee, but Hader bounced back in September and played a key role in the team’s postseason push.
On January 13, 2023, Hader signed a one-year, $14.1 million contract to avoid arbitration. He opened the year with 10 saves in April and was named NL Reliever of the Month. He became a free agent after the 2023 season, opening the door to a new chapter in Houston.

On January 22, 2024, Hader signed a five-year, $95 million contract with the Houston Astros, joining one of the American League’s most consistent contenders. He made his Astros debut early in the season and quickly delivered, recording a career-high 34 saves in 71 appearances while finishing 8–8 with a 3.80 ERA and 105 strikeouts. He set a new franchise record by converting 25 consecutive save opportunities, surpassing Brad Lidge’s previous mark, and was named AL Reliever of the Month in August. On September 13, 2024, he recorded his 30th save of the season as the Astros became the first MLB franchise to reach 5,000 wins.
Hader’s success carried into 2025, when he earned his 200th career save on Opening Day by striking out Juan Soto of the New York Mets. He set another club record on June 27 by converting his 22nd straight save to start the season, breaking a mark that had stood since 1989, and was named AL Reliever of the Month for June. He was selected to the 2025 MLB All-Star Game, his sixth career All-Star nod, before a left shoulder capsule sprain in mid-August ended his season. He made 48 appearances, going 6–2 with a 2.05 ERA, 28 saves, and 76 strikeouts in 52⅔ innings.
