A first-round pick in the 2016 MLB draft by the Washington Nationals, Dunning has built a reputation for durability and steady performance, with his career highlight coming as a member of the 2023 World Series champion Texas Rangers.

Early Life and Background
Dane Anthony Dunning was born and raised in Green Cove Springs, Florida, the son of John Dunning, his American father, and Misu Dunning, his Korean mother. Growing up in a supportive household, Dunning was introduced to baseball at a young age and developed his skills throughout his childhood in northeast Florida. His older brother, Jake Dunning, also went on to pitch in Major League Baseball, creating a clear baseball lineage within the family that helped shape Dane’s early ambitions.
Dunning attended Clay High School in Green Cove Springs, where he emerged as one of the top pitching prospects in the region. His performance on the high school mound drew attention from college scouts across the country. After graduating, Dunning chose to play college baseball at the University of Florida, where he suited up for the Florida Gators and continued to develop his craft against some of the best competition in NCAA Division I baseball.
Path to Professional Baseball
At the University of Florida, Dunning split his time between the starting rotation and the bullpen, showing the kind of versatility that would later become a hallmark of his professional career. As a freshman, he appeared in 17 games, and by his sophomore year he had transitioned into a starting role, finishing with a 4.03 ERA across 16 appearances. His junior season saw him return to a relief role, where he posted a 2.29 ERA and pitched 15.1 innings in the 2016 NCAA Division I baseball tournament, allowing only one run.
Following his junior season, Dunning was selected by the Washington Nationals in the first round of the 2016 MLB draft, validating his years of work in college. He split his first professional season between the Gulf Coast League Nationals and the Auburn Doubledays, posting a combined 3–2 record and a 2.02 ERA across eight games. On December 7, 2016, the Nationals traded Dunning, along with Reynaldo López and Lucas Giolito, to the Chicago White Sox in exchange for Adam Eaton, beginning the next chapter of his career.
Dane Dunning Career
Early Career (2017–2019)
Dunning began his professional journey in the White Sox system, where he was assigned to the Kannapolis Intimidators in 2017. After posting a 0.35 ERA across 26 innings, he was promoted to the Winston-Salem Dash, where he finished the year with a 6–8 record and 3.51 ERA in 22 starts. In 2018, Dunning split time between Winston-Salem and the Birmingham Barons, pitching to a combined 6–3 record and 2.71 ERA in 15 starts, showing continued growth as a prospect.
On March 18, 2019, Dunning underwent Tommy John surgery after suffering a torn ulnar collateral ligament, a procedure performed by Dr. James Andrews. The injury forced him to miss the entire 2019 season, but the White Sox added him to their 40-man roster on November 20 to protect him from the Rule 5 draft, signaling their confidence in his long-term potential.
Chicago White Sox Era (2020)
Dunning made his Major League Baseball debut on August 19, 2020, in a game against the Detroit Tigers, where he struck out seven batters and allowed just one walk in 4.1 innings, earning the win in a 5–3 victory. With the 2020 Chicago White Sox, he appeared in seven games and compiled a 2–0 record with a 3.97 ERA and 35 strikeouts across 34 innings, capping a successful first taste of the big leagues.
Texas Rangers Era (2021–2025)
On December 7, 2020, the White Sox traded Dunning and Avery Weems to the Texas Rangers in exchange for Lance Lynn, marking the start of his longest MLB tenure. During the 2021 season, Dunning finished with a 5–10 record and a 4.51 ERA, recording 114 strikeouts across 117.2 innings. The following year, he went 4–8 with a 4.46 ERA and 137 strikeouts over 153.1 innings, but his season ended early after he underwent surgery to repair a torn labrum in his right hip.
Dunning’s 2023 campaign was his most accomplished, as he made 35 appearances, including 26 starts, posting a 12–7 record and a 3.70 ERA with a career-high 140 strikeouts across 172.2 innings. The Rangers went on to defeat the Arizona Diamondbacks in the 2023 World Series, giving Dunning his first championship ring. He was also named the Texas Rangers Pitcher of the Year for 2023. In 2024, Dunning appeared in 26 games with 15 starts, finishing 5–7 with a 5.31 ERA and 91 strikeouts over 95 innings.
In 2025, Dunning experienced a turbulent season with Texas, being removed from the 40-man roster and sent to the Triple-A Round Rock Express on March 25. He was recalled on April 28, designated for assignment on April 30, sent back to Round Rock on May 3, and recalled again on June 23 before being optioned once more on June 28 to make room for Nathan Eovaldi. He was recalled again on July 1, marking an up-and-down year at the MLB level.
Atlanta Braves Era (2025)
On July 17, 2025, the Rangers traded Dunning to the Atlanta Braves in exchange for José Ruiz and cash considerations. In seven appearances for Atlanta, he struggled to a 10.80 ERA with 11 strikeouts across 10 innings. On October 1, Dunning was removed from the 40-man roster and sent outright to the Triple-A Gwinnett Stripers, and he elected free agency the following day, becoming a free agent.
Driving Style and Strengths
Dunning relies on command, pitch mix, and composure rather than overpowering velocity, making him effective at inducing weak contact and limiting walks. His ability to work deep into games has been a defining trait, and he has shown resilience after recovering from both Tommy John surgery and hip surgery to return to the mound at the major league level.
Notable Events and Milestones
Dunning’s signature moment came in 2023, when he helped the Texas Rangers win the World Series and was named the organization’s Pitcher of the Year. His MLB debut in 2020, where he struck out seven Tigers in 4.1 innings, also stands as one of the most memorable early milestones of his career.
