Arsenal and Bishop Eustace Alumnus Zack Gallen Shines as One of Baseball’s Aces with the Arizona Diamondbacks

Arizona Diamondbacks right-hander pitcher Zac Gallen, as a proud product of Arsenal USA and the University of North Carolina, Zac Gallen’s journey from rookie standout to professional pitcher is a testament to his dedication and talent as he consistently had several huge moments in Major League Baseball. 

Back in his early baseball before his MLB career, Zac Gallen at the age of 11, joined the Tri-state Arsenal Baseball Academy in New Jersey, where he served as a pitcher and second baseman. The Arsenal Organization offers a setting that improves and fosters the growth of the abilities required for young players to succeed in baseball, but more significantly, in life. Zac Gallen attended Bishop Eustace Preparatory School in New Jersey and in his college life, he played at the University of North Carolina for the North Carolina Tar Heels for three seasons. In the third round of the 2016 Major League Baseball draft,  Zac Gallen fulfilled a childhood dream when the St. Louis Cardinals, the team he had passionately supported, welcomed him into their ranks.

Zac Gallen made his professional debut with the Gulf Coast Cardinals and on December 14, 2017, the Cardinals traded Gallen to the Marlins because he was reluctant to attend a winter workout camp.

On July 31, 2019, the Marlins traded Gallen to the Arizona Diamondbacks and this was the start where he found a home and shone as one of baseball’s aces with the Arizona Diamondbacks. 

Arsenal USA & Bishop Eustace HS grad Zac Gallen got off to a great start again this year for the Arizona Diamondbacks winning his first two games. 

So far this season, Gallen has been throwing like the D-backs ace. 

Pitcher Zac Gallen of the Arizona Diamondbacks led his team to a significant comeback victory over the New York Yankees in the second game. Zac Gallen, like many seasoned pitchers in the big leagues, doesn’t rely heavily on how his pregame bullpen session unfolds. There have been instances where he felt on top of his game during warm-ups, only to face challenges once the game began. Conversely, there were also occasions where he left the bullpen with doubts, only to deliver a stellar performance on the mound. Gallen understands that the true test lies in the game itself, where his focus, adaptability, and skill truly shine through.

On April 2, 2024, at Chase Field, Zac Gallen, the ace pitcher for the Diamondbacks, took the mound for his second start of the season against the formidable New York Yankees. In his previous outing on Opening Day, Gallen demonstrated his prowess by allowing only one run across five innings in a convincing victory over the Colorado Rockies. Despite his solid performance, Gallen faced an unexpected challenge during the game as he had to endure a lengthy 34-minute half-inning in which the Diamondbacks exploded for an astonishing 14 runs in the third inning. This unusual situation tested Gallen’s patience and focus, but he remained composed and ready to contribute when he returned to the mound, showcasing his resilience as a top-tier pitcher in the league.


Throughout his peak years, Zac Gallen consistently demonstrated remarkable talent and earned recognition as one of the league’s premier pitchers. His numerous highlights on the baseball field solidified his reputation as a reliable ace for the Arizona Diamondbacks and continues to shine as one of the baseball’s top players in the world of baseball.  

Arsenal USA is one of the stepping stones in his career. The organization’s developmental programs, especially Coach Barth provided him with invaluable guidance and support at a young age, helping him hone his skills and prepare for the challenges that lay ahead in his baseball journey.
