Matt Gage Bio
Matthew Robert Gage, known professionally as Matt Gage, is an American professional baseball pitcher for the San Francisco Giants of Major League Baseball (MLB). Born on February 11, 1993, in Johnstown, New York, he has built a long professional career through perseverance, bouncing between organizations, independent leagues, and international competition before reaching a stable role in the majors.
A left-handed pitcher, Gage has suited up for the Toronto Blue Jays, Houston Astros, Detroit Tigers, and the San Francisco Giants, in addition to spending time in the minor league systems of several other clubs. Through the 2025 season, he had posted a 4–3 record with a 3.09 earned run average (ERA) and 67 strikeouts in his major league career, the bulk of which came in relief appearances.
Early Life and Background
Matthew Robert Gage grew up in Johnstown, New York, a small community in the Mohawk Valley region of upstate New York. He attended Broadalbin-Perth High School in nearby Broadalbin, where he developed as a pitcher and drew attention from college recruiters for his work on the mound.
After high school, Gage continued his playing career at Siena College, a small school in Loudonville, New York, competing for the Siena Saints baseball program. Over three seasons with the Saints, he logged an 11–16 win–loss record, a 3.99 ERA, and 212 strikeouts in 248⅓ innings, showing the kind of workload expected of a frontline college starter. During the summer of 2013, he played collegiate summer baseball for the Chatham Anglers of the prestigious Cape Cod Baseball League and was named a league all-star, a strong signal that he was on professional scouts’ radar.
Path to Baseball
Gage entered professional baseball when the San Francisco Giants selected him in the 10th round of the 2014 Major League Baseball draft. The Giants assigned him to the Rookie-level Arizona League Giants for the remainder of that season, where he appeared in 13 games, going 2–0 with a 1.89 ERA and 32 strikeouts, a strong first impression for a late-round pick.
Over the next several years, Gage moved steadily through the Giants’ minor league system, pitching for the Class-A Augusta GreenJackets, the Double-A Richmond Flying Squirrels, and the Triple-A Sacramento River Cats. He posted a 9–7 record with a 3.38 ERA for Richmond in 2016 and reached Triple-A in 2017, when he was named a mid-season All-Star. After struggling to a 6.45 ERA across appearances in Richmond and Sacramento in 2018, the Giants released him on July 13 of that year, forcing Gage to navigate the uncertain waters of independent and international baseball before returning to affiliated ball.
Matt Gage Career
Early Career (2014–2018)
Gage’s earliest professional years were spent inside the San Francisco Giants organization, where he climbed from short-season ball to the upper minors. In 2015, he split the year between Augusta and Richmond, finishing 6–7 with a 4.27 ERA and 101 strikeouts in 116 innings, valuable experience for a young starter adjusting to a full professional workload.
His 2016 season at Richmond marked his first extended run as a starting pitcher in the upper minors. He made 23 starts, going 9–7 with a 3.38 ERA and 106 strikeouts in 136 innings, and reached Triple-A Sacramento in 2017. After a down year in 2018, however, the Giants released him in mid-July, ending his first stint with the only organization he had ever known.
Independent and International Baseball (2018–2020)
Released by the Giants, Gage signed a minor league deal with the New York Mets on August 4, 2018, and pitched for the Double-A Binghamton Rumble Ponies and the Triple-A Las Vegas 51s, going 7–11 with a 5.16 ERA in 20 combined appearances. He elected free agency after the season and headed abroad, signing with the Diablos Rojos del México of the Mexican League on April 3, 2019. With the Diablos, he went 10–4 with a 5.57 ERA and 106 strikeouts in 118 innings, showing he could handle a heavy workload against experienced hitters.
The cancellation of the 2020 minor league season due to the COVID-19 pandemic pushed Gage into independent baseball. He played for the Eastern Reyes del Tigre of the Constellation Energy League, recording a 3.07 ERA with 16 strikeouts in 14⅔ innings. That brief stint helped him stay sharp and ready for another chance in affiliated ball.
Arizona Diamondbacks and Toronto Blue Jays (2021–2022)
On February 9, 2021, Gage signed with the Arizona Diamondbacks organization and converted to a full-time relief role. He appeared in 43 games split between the Double-A Amarillo Sod Poodles and Triple-A Reno Aces, going 4–1 with a 4.14 ERA and 58 strikeouts in 45⅔ innings, demonstrating the kind of swing-and-miss stuff that plays in shorter outings.
On November 29, 2021, he signed a minor league contract with the Toronto Blue Jays and was invited to spring training. He opened 2022 with the Triple-A Buffalo Bisons, posting a 1.08 ERA in 16⅔ innings before the Blue Jays promoted him to the majors on June 6, 2022. That night, he made his MLB debut with a scoreless inning of relief against the Kansas City Royals, recording his first major league strikeout against Kyle Isbel. He finished his rookie year with 11 appearances, a 1.38 ERA, and 12 strikeouts in 13 innings for Toronto.
Houston Astros and Dodgers (2023–2024)
The Blue Jays designated Gage for assignment in late January 2023 and released him in early February, but the Houston Astros claimed him off waivers on February 13, 2023. He began the year with the Triple-A Sugar Land Space Cowboys, going 1–1 with a 4.82 ERA in 34 games, then was recalled on May 2 to replace the injured Luis García. In five appearances for Houston, he posted a 2.70 ERA with eight strikeouts in 6⅔ innings before being designated for assignment in January 2024 to make room for Josh Hader on the 40-man roster.
Gage was claimed by the New York Yankees in late January 2024 and then traded a week later to the Los Angeles Dodgers, along with Christian Zazueta, in exchange for Caleb Ferguson. He spent most of 2024 in the minors with the Triple-A Oklahoma City Baseball Club, going 1–3 with a 4.29 ERA in 20 games, and was traded to the New York Mets on July 7. Called up briefly in late July, he did not appear for the Mets’ big league club and elected free agency in November.
Detroit Tigers and San Francisco Giants (2024–Present)
On December 21, 2024, Gage signed a minor league deal with the Detroit Tigers and opened 2025 with the Triple-A Toledo Mud Hens. He posted a 1–1 record and 1.67 ERA with 28 strikeouts and three saves in 32⅓ innings, earning a call-up on June 12, 2025. He made six scoreless appearances for Detroit, striking out three over 5⅔ innings, before being designated for assignment following the promotion of Dietrich Enns on June 26. He cleared waivers and elected free agency on July 1.
On July 2, 2025, Gage signed a minor league contract with the San Francisco Giants, returning to the organization that first drafted him. After five scoreless appearances for the Triple-A Sacramento River Cats, the Giants selected his contract on July 18, and he made his first career MLB start on July 27, 2025, against the New York Mets. Serving as an opener, he retired Brandon Nimmo, Francisco Lindor, and Juan Soto on 10 pitches in a single inning. Across 27 appearances for the Giants in 2025, he went 0–1 with a 3.91 ERA and 24 strikeouts in 25⅓ innings, finishing the year with 0–1 record, 3.19 ERA, and 27 strikeouts in 31 innings over 33 total appearances between Detroit and San Francisco.
Driving Style and Strengths
Since transitioning to a relief role in 2021, Gage has shown he can handle short bursts of high-leverage work, leaning on a low-to-mid-90s fastball and a sharp breaking ball to generate swings and misses. He has excelled in shorter outings, posting ERAs under 2.00 in two of his last three Triple-A stints and limiting left-handed hitters throughout his career. His ability to miss bats, combined with his poise under pressure, has made him a useful left-handed option out of the bullpen.
Notable Events and Milestones
Gage’s biggest milestone came on June 6, 2022, when he made his MLB debut for the Toronto Blue Jays and recorded a scoreless inning against the Kansas City Royals, earning his first big league strikeout against Kyle Isbel. His first career MLB start came on July 27, 2025, when he served as an opener for the San Francisco Giants against the New York Mets and retired the heart of the Mets’ order on 10 pitches. His journeyman path, spanning affiliated ball, the Mexican League, independent baseball, and now his original organization, stands as a defining story of his career.
