Bryce Miller Bio
Bryce Austen Miller (born August 23, 1998) is an American professional baseball pitcher for the Seattle Mariners of Major League Baseball (MLB). He made his MLB debut in 2023 and has since developed into a dependable starting pitcher in the Mariners’ rotation. Known for his strikeout ability and early-career control, Miller has already set multiple franchise and league records within his first seasons in the majors.
Early Life and Background
Bryce Austen Miller grew up in New Braunfels, Texas, where he attended New Braunfels High School. He played for the New Braunfels Unicorns baseball team alongside Jordan Westburg, a childhood friend who grew up in the same neighborhood. Both players graduated from the school in 2017, and their parallel journeys would eventually carry them both to professional baseball.
During his high school years, Miller’s favorite baseball player was Lance Berkman, a former MLB slugger. That admiration for established big-league talent helped shape Miller’s competitive approach as he prepared for the next level of the sport.
Path to Baseball
After high school, Miller began his college baseball career at Blinn College, a community college in Texas. In 2018, he posted a 7–1 record with five saves across twenty relief appearances, drawing attention from MLB scouts. The Miami Marlins selected him in the thirty-eighth round of the 2018 MLB Draft, but Miller chose not to sign, opting instead to continue his development.
He transferred to Texas A&M University, where he played for the Aggies baseball team for three seasons. Miller served as a reliever in his first two years, leading the team with three saves during the shortened 2020 season, before converting to a starting pitcher in 2021. He also gained valuable summer experience with the Brazos Valley Bombers of the Texas Collegiate League in 2018 and 2020, and with the Falmouth Commodores of the Cape Cod Baseball League in 2019.
Bryce Miller Career
Early Career (2018–2021)
Miller’s professional career began after the Seattle Mariners selected him in the fourth round with the 113th overall pick of the 2021 MLB Draft. He signed with the team for a $400,000 bonus and made his professional debut with the Single-A Modesto Nuts, where he logged 9 1/3 innings across five games with a 4.82 ERA.
In 2022, Miller split his season between Modesto, the High-A Everett AquaSox, and the Double-A Arkansas Travelers. Across 27 appearances and 26 starts, he posted a combined 7–4 record with a 3.16 ERA and 163 strikeouts in 133 2/3 innings, cementing his reputation as a rising pitching prospect.
MLB Debut and Rookie Season (2023)
Miller began the 2023 season back with Arkansas, where he struggled to a 0–2 record and a 6.41 ERA in four April starts. On May 1, the Mariners announced that he would be promoted to the major leagues to start against the Oakland Athletics. In that debut, he carried a perfect game into the sixth inning before giving up a one-out single to Tony Kemp, finishing with six innings, one earned run, and 10 strikeouts, a Mariners franchise record for most strikeouts in a debut.
His first three MLB starts were historically efficient. Miller allowed only eight baserunners across those outings, breaking an MLB record that had stood since 1901 for fewest baserunners allowed in a pitcher’s first three starts (minimum 15 innings pitched). He also posted the lowest WHIP in first three starts in MLB history at 0.421. On May 24, he became the first pitcher since 1901 to pitch at least six innings while allowing four or fewer hits in each of his first five career appearances.
A blister on his finger sent Miller to the injured list on July 3. He returned on July 16 to pick up his sixth win of the season, though his performance cooled late in the year. He closed 2023 with an 8–7 record, a 4.32 ERA, and 119 strikeouts in 131 1/3 innings.
Second Season Surge (2024)
Miller’s second MLB season in 2024 marked a clear step forward. He finished with a 12–8 record, a 2.98 ERA, and 171 strikeouts across 180 1/3 innings. His 2.98 ERA ranked eighth in the majors, and his 1.068 walks and hits per inning pitched ranked fourth. Seven times during the season, he pitched seven innings while allowing zero or one run, showcasing his growing consistency as a frontline starter.
Seattle Mariners Era (2023–Present)
Since his promotion in May 2023, Miller has remained with the Seattle Mariners. Through his first two-plus major league seasons, he has built a 27–22 record, a 3.79 ERA, and 407 strikeouts. Wearing jersey No. 50, he continues to anchor a young Mariners rotation and remains a central part of the club’s long-term pitching plans.
Driving Style and Strengths
Miller is recognized for his control, efficiency, and ability to generate swings and misses. He has shown particular strength in limiting baserunners and going deep into starts, often allowing fewer than one baserunner per inning. His transition from college reliever to professional starter has highlighted his adaptability and his command of multiple pitches.
Notable Events and Milestones
Miller’s most celebrated moments came in the opening weeks of his MLB career. His debut strikeout record, his record-low baserunner total through three starts, and his place as the first pitcher since 1901 to pitch six innings with four or fewer hits in each of his first five appearances stand out as signature early achievements.

2025 Season Performance
Heading into the 2025 season, Bryce Austen Miller is expected to remain a key piece of the Seattle Mariners’ starting rotation. Building on his strong 2024 finish, he enters the year with momentum and an established role in the team’s plans.
His career totals, including 27 wins, 407 strikeouts, and a 3.79 ERA, reflect a pitcher who has steadily improved since his 2023 debut. If he can build on his 2.98 ERA from 2024, Miller has a strong chance to position himself as one of the Mariners’ top arms in the American League.
