Erik Miller Bio
Erik Christopher Miller (born February 13, 1998) is an American professional baseball pitcher for the San Francisco Giants of Major League Baseball (MLB). A left-handed reliever who came up through the Philadelphia Phillies organization, Miller made his MLB debut in 2024 and has been a steady presence in the Giants’ bullpen. He wears jersey number 68 for San Francisco.
Miller first gained attention as a hard-throwing lefty at De Smet Jesuit High School before spending three seasons at Stanford University. The Phillies drafted him in 2019, and after a trade in January 2023, he advanced through the Giants’ minor league system before reaching the major leagues.
Early Life and Background
Erik Christopher Miller grew up in the St. Louis area and attended De Smet Jesuit High School in Creve Coeur, Missouri, where he developed into one of the region’s top pitching prospects. During his junior year in 2015, he went 5–1 with a 3.58 ERA, and as a senior in 2016, he posted a 3–4 record with a 3.14 ERA.
Although several professional scouts expressed interest in Miller, he told them directly by email that he would not sign if drafted and intended to honor his college commitment. As a result, he went unselected in the 2016 Major League Baseball draft and enrolled at Stanford University.
Path to Baseball
Miller joined the Stanford Cardinal and quickly became a fixture in their rotation. As a freshman in 2017, he appeared in 17 games, making 13 starts and four relief appearances, going 5–2 with a 3.65 ERA. That summer he pitched for the Newport Gulls of the New England Collegiate Baseball League.
During his sophomore season in 2018, Miller started 13 games and went 4–4 with a 4.07 ERA, striking out 52 batters over 48 and 2/3 innings. He followed that with a stint in the Cape Cod Baseball League with the Orleans Firebirds. In his junior year of 2019, he started 15 games and logged a 3.15 ERA with 97 strikeouts across 80 innings, cementing his status as a top college pitching prospect.
Erik Miller Career
Early Career (2019–2020)
The Philadelphia Phillies selected Miller in the fourth round of the 2019 MLB draft and signed him for $428,300. He made his professional debut that year, splitting time between the Rookie-level Gulf Coast League Phillies, the Low-A Williamsport Crosscutters, and the Single-A Lakewood BlueClaws. Across 11 games and seven starts covering three clubs, Miller went 1–0 with a 1.50 ERA and recorded 52 strikeouts over 36 innings, an outstanding 13.0 strikeouts per nine innings.
Miller did not appear in any games in 2020 after the minor league season was canceled because of the COVID-19 pandemic. The Phillies invited him to major league spring training in 2021 as a non-roster invitee, but he began the year on the injured list and pitched only 12 and 2/3 innings during the regular season. After the season he represented the Phillies in the Arizona Fall League with the Peoria Javelinas.
Phillies Organization Breakthrough (2022)
Miller opened 2022 with the Reading Fightin Phils of the Double-A Eastern League, where his performance earned him a spot representing the Phillies at the 2022 All-Star Futures Game. In mid-August he was promoted to the Lehigh Valley IronPigs of the Triple-A International League. Over 32 games and seven starts between the two affiliates, he went 1–1 with a 3.54 ERA, 62 strikeouts, and 31 walks in 48 and 1/3 innings, posting 11.5 strikeouts per nine innings.
His repertoire during this stretch drew attention from evaluators. Miller threw a fastball that could reach 98 mph, complemented by a low-80s slider and a changeup. The combination of velocity and breaking-ball depth positioned him as a potential late-innings reliever.
San Francisco Giants Era (2023–Present)
On January 9, 2023, the Phillies traded Miller to the San Francisco Giants in exchange for Yunior Marte, launching the next phase of his career. In 54 appearances split between the Double-A Richmond Flying Squirrels and Triple-A Sacramento River Cats, he posted a 2.45 ERA with 88 strikeouts and 15 saves over 62 and 1/3 innings. On November 14, 2023, the Giants added Miller to their 40-man roster to protect him from the Rule 5 draft.
Miller was optioned to Triple-A Sacramento to begin the 2024 season, but a wave of injuries in the Giants’ bullpen led to his recall and a place on the Opening Day roster. He made 73 appearances during his rookie campaign, going 4–5 with a 3.88 ERA and 87 strikeouts across 67 and 1/3 innings. He began the 2025 season strong, making 36 appearances with a 4–1 record and a 1.50 ERA over 33 innings, before a left elbow sprain later specified as a mild UCL sprain sent him to the injured list on July 5, 2025. He was transferred to the 60-day injured list on August 21.
Driving Style and Strengths
Miller relies on a power left-handed arsenal anchored by a fastball that can touch 98 mph, paired with a low-80s slider and a changeup. His high strikeout rates at every level reflect the swing-and-miss quality of his breaking ball, and his performance in high-leverage minor league innings demonstrated the composure needed for late-inning work.
Notable Events and Milestones
Among the highlights of Miller’s rise were his selection to the 2022 All-Star Futures Game, his 2023 trade to the Giants, and his MLB debut in 2024. He reached the major leagues after being added to San Francisco’s 40-man roster to shield him from the Rule 5 draft, a milestone that signaled the organization’s belief in his long-term potential.
Erik Miller Career Wins
While Miller’s major league role has been primarily as a reliever, his career win totals reflect his development across the minor leagues and his growing presence in the Giants’ bullpen. Through June 19, 2026, his MLB line showed an 8–6 record, a 3.38 ERA, and 137 strikeouts.
Minor League Highlights
Miller’s professional win total began in 2019 with a 1–0 record across three affiliates and a 1.50 ERA. Across his time in the Phillies system, including a 1–1 mark with a 3.54 ERA in 2022 and a 2.45 ERA over 54 appearances with Richmond and Sacramento in 2023, he consistently delivered high strikeout totals and limited damage. His first MLB victory came during his rookie season with the Giants in 2024, when he went 4–5 with a 3.88 ERA across 73 appearances.
Other Wins and Performances
Miller’s summer collegiate stints with the Newport Gulls and the Orleans Firebirds gave him early exposure to competitive environments beyond the Pac-12 schedule. His invitation to the Arizona Fall League with the Peoria Javelinas after 2021 and his appearance in the All-Star Futures Game in 2022 underscored his standing among baseball’s top prospects.

2025 Season Performance
Miller opened the 2025 season as a key left-handed option in the Giants’ bullpen and quickly delivered one of the most efficient stretches of his career. Through 36 appearances, he posted a 4–1 record and a 1.50 ERA with 22 strikeouts over 33 innings, giving San Francisco a dependable bridge to the late innings.
His momentum was interrupted on July 5, 2025, when he was placed on the injured list with a left elbow sprain that was later identified as a mild UCL sprain. On August 21, the Giants transferred him to the 60-day injured list, ruling him out for the remainder of the season.
Looking ahead, Miller remains a core part of San Francisco’s relief plans once he recovers. His combination of upper-90s velocity and a sharp slider positions him for a full bounce-back, with the Giants expected to carefully manage his return from the UCL injury.
