Jonah Heim Bio
Jonah Nathan Heim is an American professional baseball catcher who plays in Major League Baseball (MLB). Born in Buffalo, New York, Heim has played for the Oakland Athletics, Texas Rangers, and Atlanta Braves since making his MLB debut in 2020. He became a starter in Texas and reached the top of the sport when he helped the Rangers win the 2023 World Series, while also earning an All-Star selection and a Gold Glove Award that same season. He is the father of three children and the husband of his wife Mackenzie.
A late-round draft pick who developed slowly in the minor leagues, Heim earned his role behind the plate by sharpening his defense and switch-hitting approach. His journey from Buffalo winters to a championship ring has made him one of the more recognizable catching stories of his generation.
Early Life and Background
Jonah Nathan Heim was born on June 27, 1995, in Buffalo, New York. Growing up in western New York, he became a childhood fan of the New York Yankees and admired catchers such as Jorge Posada and Russell Martin. He often watched minor league baseball at Sahlen Field, home of the Buffalo Bisons, and began playing baseball himself at the age of two. Around the time he turned 12, Heim took up switch hitting and reportedly told his father that hitting from the right side was boring.
Heim attended Kenmore East High School for one year before transferring to Amherst Central High School. The harsh climate in Buffalo limited outdoor play to roughly twenty games each season, and the team played in a stadium without an outfield wall, so home runs often landed in nearby backyards or soccer fields. Despite those conditions, Heim batted .470 and picked off twelve baserunners during his junior year, drawing the attention of scouts and college recruiters. Amherst retired his No. 6 jersey shortly after his 2013 graduation.
Path to Baseball
The Baltimore Orioles selected Heim in the fourth round, 129th overall, of the 2013 MLB Draft. He had committed to play college baseball at Michigan State but chose to turn pro and signed with Baltimore for a $389,700 bonus. He was assigned to the Rookie-level Gulf Coast League Orioles and struggled at the plate, batting .185 with four runs batted in during his first season. Orioles hitting coach Jeff Manto pointed to Heim’s limited outdoor experience as a key reason for the slow start.
Heim split the 2014 season between the GCL Orioles and the Aberdeen IronBirds, batting a combined .196. He returned to full-season ball in 2015 with the Delmarva Shorebirds of the Single-A South Atlantic League and improved to a .252 average, earning a midseason foot injury and a rehab assignment before returning in September. Promoted to the Frederick Keys in 2016, Heim was named a Carolina League All-Star and later described that stretch as a turning point in his offensive development, even though his lifetime average in the Orioles system sat at .216 across eighty-eight games.
Jonah Heim Career
Baltimore Orioles and Tampa Bay Rays (2013-2017)
On August 1, 2016, Baltimore traded Heim to the Tampa Bay Rays in exchange for veteran Steve Pearce. Tampa Bay assigned him to the High-A Charlotte Stone Crabs, where he drove in the winning run in his Florida State League debut. Between Frederick and Charlotte he batted .217 with eight home runs and thirty-three runs batted in across 102 games that year. He opened 2017 in the Low-A Bowling Green Hot Rods, where he batted .268 with nine home runs and fifty-three runs batted in, then earned a promotion back to the Stone Crabs in August.
On December 19, 2017, Heim was traded to the Oakland Athletics as the player to be named later in a deal for Joey Wendle. He split 2018 between the High-A Stockton Ports and the Double-A Midland RockHounds, batting .258 with eight home runs and sixty runs batted in. In 2019 he moved between Midland and the Triple-A Las Vegas Aviators, hitting a combined .310 with nine home runs and fifty-three runs batted in, which prompted Oakland to add him to the 40-man roster on November 1, 2019.
Oakland Athletics Breakthrough (2020)
When Minor League Baseball canceled the 2020 season because of the COVID-19 pandemic, Heim spent the summer at Oakland’s alternate training site, working with major league pitchers during bullpen sessions. On August 24, 2020, the Athletics promoted him to the active roster, and he made his MLB debut the next day, starting behind the plate in a 10-3 win over the Texas Rangers. He recorded his first major league hit, a single off Kyle Gibson, in the seventh inning.
Heim served as a backup to Sean Murphy and appeared in thirteen regular season games, batting .211 with five runs batted in. Oakland included him on the postseason roster, although he did not play in the playoffs as the Athletics beat the Chicago White Sox in the Wild Card Series before being eliminated by the Houston Astros in the American League Division Series.
Texas Rangers Era (2021-2025)
On February 6, 2021, Oakland traded Heim, Khris Davis, and Dane Acker to the Texas Rangers for Elvis Andrus and Aramis Garcia. He hit his first major league home run on April 6, 2021, off Toronto’s Tommy Milone, and on July 31 he blasted his first career walk-off home run against Seattle’s Diego Castillo, then repeated the feat the next day to become the first rookie in MLB history to record walk-off homers in consecutive games. In a 2022 visit to Sahlen Field during the Blue Jays’ pandemic relocation, Heim played a major league series in his hometown of Buffalo. He also hit his first career grand slam on April 14, 2022, off Shohei Ohtani of the Los Angeles Angels.
The 2023 season defined his career. Heim was voted the American League starting catcher for the 2023 MLB All-Star Game and went on to hit .258 with eighteen home runs and ninety-five runs batted in over 131 games. With the Rangers, he won the 2023 World Series and earned the American League Gold Glove Award for catcher. He played another 131 games in 2024 and 124 in 2025, before Texas non-tendered him on November 21, 2025, making him a free agent.
Atlanta Braves and Athletics Return (2026)
On February 10, 2026, Heim signed a one-year, $1.5 million contract with the Atlanta Braves. He appeared in twelve games for Atlanta, slashing .231 with one home run and eight runs batted in before being designated for assignment on May 4, 2026. The Athletics then acquired him in exchange for cash considerations on the same day, beginning a second stint with the organization that first promoted him to the majors.
Driving Style and Strengths

Notable Events and Milestones
His signature stretch came in 2023, when he started the All-Star Game, won a World Series ring with Texas, and earned Gold Glove honors.

Jonah Heim Family
Family Background and Racing Lineage
Heim’s family supported his baseball development from a young age, with his parents moving out of the Kenmore East school district so he could continue playing in a more favorable program. His father is referenced as a sounding board during his early switch-hitting decision, and the family remains connected to the Buffalo community where he grew up.
Personal Life
Heim and his wife Mackenzie have three children. Their son Nash was born in January 2021, their daughter Luxx was born in April 2022, and their son Champ was born in June 2024. Heim also has a tattoo of the Buffalo skyline on his arm, a nod to his hometown.
2025 Season Performance
Heim’s 2025 campaign with the Texas Rangers included 124 appearances, during which he batted .213 with eleven home runs and forty-three runs batted in. His role as the everyday catcher remained intact through most of the year, though his offensive production trended below his 2023 peak. The Rangers finished the season outside the postseason picture.
On November 21, 2025, Texas non-tendered Heim, allowing him to reach free agency for the first time in his career. The move opened the door for him to sign with Atlanta in February 2026 and, after a brief stint with the Braves, return to the Athletics via trade in May 2026, where he continues to serve as a veteran catching option. With his Gold Glove pedigree and World Series experience, Heim remains a viable starting or backup catcher as the 2026 season unfolds.
