Milwaukee Brewers pitcher Jacob Misiorowski has drawn growing attention for his powerful fastball and rapid rise in Major League Baseball, but his family remains an important part of his success story. His parents, Tom and Crystal Misiorowski, have supported his baseball ambitions since childhood in Blue Springs, Missouri. One of the most meaningful moments came in June 2025, when Jacob honored his father, who lives with Parkinson’s disease, by wearing specially designed baseball cleats to raise awareness of the condition.
The young right-handed pitcher has become one of Milwaukee’s most recognizable emerging talents. Behind his achievements is a close-knit family that supported him through high school, college, minor league baseball and his eventual arrival in the major leagues.
Who Are Jacob Misiorowski’s Parents?
Jacob Misiorowski’s parents are Tom Misiorowski and Crystal Misiorowski.
The family is from Blue Springs, Missouri, where Jacob spent much of his childhood.
Both parents played important roles in encouraging his interest in sports.
Tom helped develop Jacob’s enthusiasm for baseball, while Crystal provided emotional support throughout his athletic journey.
Their involvement became especially important as Jacob began pursuing competitive baseball.
Despite the demanding schedules associated with professional sports, the family has maintained a close relationship.
Tom and Crystal have also attended important games to celebrate their son’s achievements.
Jacob Misiorowski’s Father, Tom Misiorowski
Tom Misiorowski has been an influential figure in Jacob’s personal life and baseball development.
Before retiring, Tom worked as an electrician.
He shared a strong interest in sports with his son and encouraged Jacob to explore different athletic activities.
One of their favorite childhood traditions involved collecting trading cards.
The two spent time collecting baseball, football and Pokémon cards, creating memories that extended beyond the baseball field.
These activities helped strengthen their relationship during Jacob’s early years.
As Jacob became more serious about baseball, Tom continued supporting his ambitions.
His encouragement helped the young pitcher develop confidence and determination.
Tom Misiorowski’s Parkinson’s Disease Diagnosis
Tom Misiorowski was diagnosed with young-onset Parkinson’s disease in 2014.
At the time, Jacob was still in middle school.
The diagnosis brought significant changes to the family’s everyday life.
Parkinson’s disease is a progressive neurological condition that can affect movement, coordination and other bodily functions.
Tom eventually retired early from his work as an electrician.
Although the diagnosis created challenges, his retirement also allowed him to spend more time with Jacob.
He became increasingly involved in supporting his son’s baseball activities.
For Jacob, watching his father manage the condition provided a personal understanding of perseverance.
Their relationship has remained an important source of motivation throughout his professional career.
Jacob Misiorowski’s Tribute to His Father
In June 2025, Jacob Misiorowski used his growing MLB platform to honor his father and raise awareness about Parkinson’s disease. The Brewers pitcher wore custom New Balance cleats featuring Tom’s initials, “TM,” and a red tulip, a recognized symbol associated with Parkinson’s awareness.
The tribute was developed in connection with the Wisconsin Parkinson Association.
It reflected Jacob’s desire to bring attention to a condition that has affected his family for more than a decade.
The customized footwear carried a deeply personal message.
Rather than simply celebrating his success, Jacob used the opportunity to recognize his father’s experiences.
The gesture attracted attention from baseball fans and highlighted the close relationship between father and son.
It also demonstrated how athletes can use their visibility to support causes connected to their personal lives.
Who Is Jacob Misiorowski’s Mother, Crystal?
Crystal Misiorowski is Jacob’s mother and another important influence in his life.
She helped raise him in Blue Springs and supported his sporting interests from an early age.
As Jacob progressed through competitive baseball, Crystal remained involved in his journey.
Her encouragement became particularly valuable during the difficult stages of player development.
Professional baseball often requires young athletes to spend extended periods away from home.
Players also face challenges involving injuries, performance expectations and uncertain career opportunities.
Crystal provided emotional stability as Jacob navigated those experiences.
She has expressed pride in his determination and the values he developed while growing up in Missouri.
Despite his increasing fame, Jacob has remained closely connected to his family.
Why Does Crystal Call Him Jacob Instead of The Miz?
Jacob Misiorowski is widely known by the nickname “The Miz.”
The nickname has become popular among teammates, broadcasters and Brewers supporters.
However, his mother reportedly continues calling him Jacob.
The small family detail has attracted attention because it highlights the difference between his public identity and his life at home.
While baseball fans recognize him as a powerful pitcher, Crystal continues seeing him as the son she raised.
The nickname has become part of his professional personality, but his family relationships remain rooted in his childhood.
It is a simple reminder of the personal connections behind his growing baseball career.
His Parents Attended His MLB Debut

The occasion marked a major achievement after years of preparation and minor league development.
Tom and Crystal traveled from Missouri to Milwaukee to witness the milestone.
The journey reportedly took approximately seven hours.
They were accompanied by more than 30 relatives and close friends who wanted to support Jacob.
Their presence made the debut particularly meaningful.
For his parents, the game represented the culmination of years spent attending practices, encouraging their son and following his development.
Seeing Jacob take the mound in the major leagues was a memorable family achievement.
