Jacob Barnes Bio
Jacob Andrew Barnes is an American professional baseball pitcher who has spent more than a decade moving between Major League Baseball (MLB) organizations and the upper levels of the minor leagues. Since making his MLB debut in 2016, he has appeared for the Milwaukee Brewers, Kansas City Royals, Los Angeles Angels, New York Mets, Toronto Blue Jays, Detroit Tigers, New York Yankees, St. Louis Cardinals, and Washington Nationals, establishing himself as a steady relief arm. A free agent after the 2025 season, Barnes is a veteran right-handed reliever known for his durability and willingness to pitch in a wide variety of bullpen roles.
Early Life and Background
Jacob Andrew Barnes was born on April 14, 1990, and grew up in the St. Petersburg, Florida area. He attended St. Petersburg High School, where he developed as a pitcher and drew the attention of college recruiters. After completing his prep career, Barnes enrolled at Florida Gulf Coast University, where he joined the Florida Gulf Coast Eagles college baseball program and refined his game on the mound.
During his time at Florida Gulf Coast, Barnes worked his way into the Eagles’ weekend rotation and showed enough promise to be considered a professional prospect. In 2011, his junior year, he posted a 1–4 win–loss record with a 4.58 earned run average (ERA) across 55 innings pitched. That performance, combined with his size and arm strength, was enough to convince an MLB organization that he was ready for the next step.
Path to Professional Baseball
Following his junior season, Barnes was selected by the Milwaukee Brewers in the 14th round of the 2011 Major League Baseball draft. He signed with the organization and was assigned to the rookie-level Helena Brewers, where he made his professional debut and went 2–1 with a 2.12 ERA over 29 2/3 relief innings. The quick adjustment to pro ball signaled that Barnes could handle a relief role, which would become his calling card.
Barnes climbed the Brewers’ minor league ladder steadily. In 2012, he pitched for the Wisconsin Timber Rattlers, going 4–7 with a 3.84 ERA in 25 games including seven starts. The next year, he joined the Brevard County Manatees and turned in a strong 9–6 record and 3.08 ERA in 21 games, 14 of them starts, showing that he could both start and relieve effectively. By 2015, he was pitching for the Biloxi Shuckers and produced a 4–5 record and 3.36 ERA in 39 games with six starts, which earned him a spot on the Brewers’ 40-man roster after the season.
Jacob Barnes Career
Early Career (2016–2017)
Barnes opened 2016 with the Triple-A Colorado Springs Sky Sox and was dominant, posting a 1.21 ERA across 17 appearances. That performance convinced the Brewers to promote him to the majors on June 2, 2016, and he made his MLB debut the following day. Working exclusively out of the bullpen, Barnes went 0–1 with a 2.70 ERA in 26 2/3 innings during his first taste of the big leagues, giving Milwaukee a reliable late-inning option.
In 2017, Barnes returned to Milwaukee for his first full major league season and established himself as a regular in the Brewers’ bullpen. He appeared in 73 games, all in relief, and finished 3–4 with a 4.00 ERA. The heavy workload showed that the Brewers trusted him in a variety of situations, setting the stage for what would become a long career as a journeyman reliever.
Milwaukee Brewers Tenure (2018–2019)
Barnes began 2018 in Milwaukee’s bullpen, but a rough start to May, in which he posted a 12.00 ERA over his first four outings, led to a brief option to Colorado Springs on May 12. He was recalled on May 27 and finished the season back in the majors, regaining his form as a middle reliever.
His final stretch in Milwaukee came in 2019. After compiling a 6.86 ERA in 19 2/3 innings, Barnes was designated for assignment by the Brewers on August 1, 2019, ending his time in the organization that had drafted and developed him.
Kansas City Royals (2019)
On August 3, 2019, Barnes was claimed off waivers by the Kansas City Royals. His stay in Kansas City was brief, as the Royals designated him for assignment on November 4 and released him two days later, sending him back into free agency heading into the 2020 season.
Los Angeles Angels (2020)
Barnes signed a minor league deal with the Los Angeles Angels on January 22, 2020, and had his contract selected to the 40-man roster on July 23. He appeared in 18 games for the Angels that season and posted a 5.50 ERA, a campaign shortened by the unique circumstances of the 2020 schedule.
New York Mets (2021)
On October 30, 2020, Barnes was claimed off waivers by the New York Mets. He struggled to find consistency in 19 appearances, putting up a 6.27 ERA in 18 2/3 innings, and was designated for assignment on June 14, 2021, ending his brief Mets tenure.
Toronto Blue Jays (2021)
Barnes was traded to the Toronto Blue Jays on June 19, 2021, in exchange for Troy Miller. He made nine appearances for Toronto and posted a 6.00 ERA before being designated for assignment on July 26.

Detroit Tigers and New York Yankees (2022)
On December 1, 2021, Barnes signed a minor league contract with the Detroit Tigers with an invitation to spring training. He made the Tigers’ opening day roster, but was designated for assignment on June 13, 2022, and released on June 18. A quick stop with the Seattle Mariners organization followed, and he returned to the Tigers on a second minor league deal on July 26, pitching for the Toledo Mud Hens before being released on August 26.
On August 31, 2022, Barnes signed a minor league contract with the New York Yankees and was assigned to the Scranton/Wilkes-Barre RailRiders. The Yankees promoted him to the majors on October 1, only to designate him for assignment the next day and outright him back to Triple-A. He elected free agency on October 24.
St. Louis Cardinals and Washington Nationals (2023–2024)
After a spring 2023 stint in the Texas Rangers and Philadelphia Phillies systems, Barnes signed a minor league deal with the St. Louis Cardinals on July 19, 2023. He pitched to a 1.53 ERA across 11 appearances for the Triple-A Memphis Redbirds, earning a call-up to the majors on August 22. In 13 games for St. Louis, he recorded a 5.93 ERA before being removed from the 40-man roster after the season and electing free agency.
On February 16, 2024, Barnes signed a minor league contract with the Washington Nationals. After seven scoreless appearances for the Triple-A Rochester Red Wings, he was added to Washington’s major league roster on April 23. In 63 appearances for the Nationals, Barnes compiled an 8–3 record and a 4.36 ERA with 55 strikeouts across 66 innings, easily his most extensive and productive major league workload to that point.
