Jonah Heim

Jonah Nathan Heim (born June 27, 1995) is an American professional baseball catcher for the Athletics of Major League Baseball (MLB). He has previously played in MLB for the Texas Rangers and Atlanta Braves.

Born in Buffalo, New York, Heim attended Amherst Central High School, where the cold weather limited how often he played outdoors. The Baltimore Orioles selected him in the fourth round of the 2013 MLB draft, and he took several years to develop his offensive abilities in the Orioles' farm system. Heim was traded twice in the minor leagues, first to the Tampa Bay Rays and then to Oakland, where he made his MLB debut in 2020. The following year, the Athletics traded Heim to Texas, where he became the Rangers' starting catcher, represented the team at the 2023 MLB All-Star Game, and was a member of the 2023 World Series champions.

Early life Jonah Nathan Heim was born June 27, 1995, in Buffalo, New York. A childhood fan of the New York Yankees of Major League Baseball (MLB), Heim's favorite players were catchers like Jorge Posada and Russell Martin, and he grew up watching the Buffalo Bisons, the Toronto Blue Jays' Triple-A affiliate, although they were part of the Cleveland Guardians organization at the time, play at Sahlen Field. Heim began playing baseball when he was two years old, and around the age of 12, he took up switch hitting, telling his father, "hitting from the right side is boring".

Heim attended Kenmore East High School for one year before his parents moved out of the school district, requiring him to transfer to Amherst Central High School. The harsh climate in Buffalo meant that Heim could only play 20 outdoor baseball games in a season, and the team's stadium lacked an outfield wall, so home runs landed in nearby backyards or soccer fields. After batting .470 and picking off 12 baserunners during his junior year of high school, Heim was invited to play in several national exhibition games, where he caught the attention of professional scouts and college recruiters.

Career Baltimore Orioles The Baltimore Orioles selected Heim out of high school in the fourth round, 129th overall, of the 2013 MLB draft. At the time, Heim had committed to playing college baseball with the Michigan State Spartans, but he turned down the commitment and joined the Orioles on a $389,700 signing bonus. After signing, Heim was assigned to the Rookie-level GCL Orioles of the Gulf Coast League. He struggled in his rookie season, batting .185 with four runs batted in (RBI) in 27 games. Heim's poor hitting continued in the 2014 season, but Baltimore hitting coach Jeff Manto was unconcerned with the catcher's development, attributing it in part to his limited playing time in high school. Heim split the season between the GCL Orioles and the Aberdeen IronBirds of the Low–A New York–Penn League, batting .196 with one home run and seven RBI in 46 games.

Heim began the 2015 season with the Delmarva Shorebirds of the Single–A South Atlantic League, where he split time at catcher with Alex Murphy. He improved offensively to start the season, batting .258 with 10 extra-base hits and 16 RBI in 36 games before going on the injured list with a foot injury in May. He did not begin a rehab assignment until the end of August and returned to Delmarva on September 1. Heim finished the season batting .252 with one home run and 18 RBI in 45 minor league games. where he was named a Carolina League All-Star. Although he had a lifetime .216 batting average in 88 games for the Orioles organization, Heim cited his time in Frederick as a turning point for his offensive development.

Tampa Bay Rays On August 1, 2016, the Orioles traded Heim to the Tampa Bay Rays in exchange for veteran utility player Steve Pearce. From there, he was assigned to the High–A Charlotte Stone Crabs, where he recorded the game-winning RBI in his Florida State League debut. Between Frederick and Charlotte, Heim batted .217 in 2016, with eight home runs and 33 RBI in 102 games. There, he added an additional eight RBI on the season while batting .218 in 16 games. He spent 2018 with both the High–A Stockton Ports and the Double–A Midland RockHounds, batting .258 with eight home runs and sixty RBIs in 119 total games between both teams. He split the 2019 season between Midland and the Triple–A Las Vegas Aviators, hitting a combined .310/.385/.477/.862 with nine home runs and 53 RBIs. On November 1, 2019, Heim was added to the Athletics' 40-man roster.

On June 30, 2020, Minor League Baseball canceled the 2020 season due to the effects of the COVID-19 pandemic. As a result, Heim was one of several Athletics prospects who began the pandemic-shortened season at an alternate training site as a member of the Oakland taxi squad. While not participating in games, he spent the first part of the season working with MLB pitchers during bullpen sessions and batting practice. On August 24, the Athletics optioned backup catcher Austin Allen and promoted Heim to the active roster in his place. Heim spent the remainder of the season as a backup for Sean Murphy. He appeared in 13 regular season games, all but one of which he started at catcher. In that time, he batted .211 with no extra-base hits and five RBI. Heim was named to the Athletics' postseason roster, but he did not appear in any playoff games for Oakland. Oakland was eliminated by the Houston Astros in the 2020 American League Division Series (ALDS). After the MLB season, Heim planned to rejoin the Toros del Este for the 2020–21 Dominican Winter League season, but he recanted due to concerns surrounding the COVID-19 pandemic.

Uniquely, in July 2021, the Rangers played the Toronto Blue Jays in Heim's hometown of Buffalo, New York due to the Blue Jays' temporary relocation to Sahlen Field as a result of not being able to play at the Rogers Centre during the pandemic, resulting in Heim getting the opportunity to play a major-league series in front of a hometown crowd. Heim went 2-for-7 in the two games he played, while the Rangers were swept by the Blue Jays. Over 82 games in 2021, Heim hit .196/.239/.358/.598 with 10 home runs and 32 RBI.
