Jacob Misiorowski is an American professional baseball pitcher for the Milwaukee Brewers in Major League Baseball (MLB). Born Jacob Walter Misiorowski on April 3, 2002, in Blue Springs, Missouri, he has become one of baseball’s most exciting young pitchers. Beyond his performances on the mound, Jacob Misiorowski’s family includes his fiancée, Elle Nicas, his father, Tom Misiorowski, and his mother, Crystal Misiorowski.
As of now, Jacob Misiorowski is engaged to his longtime girlfriend, Elle Nicas, following their engagement in January 2026. The couple has no publicly confirmed children, while information about his siblings remains limited. His parents have played an important role in his baseball journey, particularly his father, whose experience living with Parkinson’s disease inspired Jacob to become involved in charitable awareness campaigns.
Jacob Misiorowski’s Girlfriend: Who Is Elle Nicas?
Jacob Misiorowski’s girlfriend and fiancée is Elle Nicas, his longtime romantic partner. Their relationship became increasingly visible as the Milwaukee Brewers pitcher gained recognition in Major League Baseball.
Elle is originally from Missouri and attended Grain Valley High School, the same school as Jacob. Both graduated in 2020, and their relationship dates back to their younger years.
Like Jacob, Elle has an athletic background. She played softball during high school, specializing as a catcher.
In July 2026, baseball reporter Russell Dorsey revealed that Misiorowski had described Elle as an exceptionally talented softball player who could throw a ball at speeds in the low 70s in miles per hour.
Her athletic ability became a subject of interest among baseball fans because Jacob is famous for throwing some of the fastest pitches in Major League Baseball.
Despite their growing public recognition, the couple has generally maintained a relatively private relationship.
Elle occasionally attends Milwaukee Brewers games and supports her partner during important professional milestones.
She accompanied Jacob to the 2025 MLB All-Star Game red-carpet event, and photographs from the occasion showed them celebrating his selection.
In July 2026, Sports Illustrated published a feature describing the close relationship between Jacob, Elle and their families.
Brewers manager Pat Murphy observed the pitcher leaving American Family Field with Elle, her parents and his mother following an impressive performance against the Philadelphia Phillies.
The moment highlighted the strong support system surrounding Misiorowski as his baseball career continued developing.
What Does Jacob Misiorowski’s Fiancée Elle Nicas Do?
Elle Nicas has a professional background in education.
According to reporting published by Sports Illustrated and TV Insider, she became a fifth-grade teacher at Matthews Elementary School in Grain Valley, Missouri, in July 2024.
Her appointment was announced through the school’s social media account, where she expressed enthusiasm about helping students develop academically and personally.
Before becoming a teacher, Elle attended Grain Valley High School and participated in the school’s softball program.
Although she is now publicly recognized as the partner of a professional baseball player, Elle has continued maintaining a comparatively private personal life.
Outside her work and baseball-related activities, she enjoys sewing, embroidery and collecting Pokémon cards.
In an October 2026 interview with MLB.com, Jacob explained that his fiancée enjoys embroidery and has encouraged him to participate in the hobby.
He admitted that he does not have the patience for sewing but appreciates their shared interest in Pokémon collectibles.
The couple has reportedly spent time collecting and organizing Pokémon cards together, an activity that reflects Jacob’s interests outside professional baseball.
Jacob Misiorowski’s Wife: Is He Married?
As of now, Jacob Misiorowski is not publicly known to be married. He is engaged to his longtime girlfriend, Elle Nicas.
The couple announced their engagement in January 2026, following Jacob’s memorable rookie season with the Milwaukee Brewers.
On January 12, 2026, Misiorowski shared a photograph on Instagram showing Elle’s hand wearing an engagement ring.
The photograph included flowers in the background, and Jacob accompanied the image with a red heart emoji.
The Milwaukee Brewers and several of his former minor league organizations congratulated him on the engagement.
In a February 2026 interview with WISN, Jacob discussed the proposal and explained that he had kept the occasion relatively simple.
He also indicated that their wedding was likely to take place during a future baseball offseason.
However, the couple has not publicly confirmed an exact wedding date.
Therefore, Elle should currently be described as Jacob Misiorowski’s fiancée rather than his wife.
Jacob Misiorowski’s Children: Does He Have a Son or Daughter?
As of now, Jacob Misiorowski and his fiancée, Elle Nicas, have no publicly confirmed children.
Available official MLB biographies, interviews and reliable sports reports do not identify the Milwaukee Brewers pitcher as the father of a son or daughter.
Misiorowski has not publicly announced the birth of a child or discussed fatherhood in established media interviews.
Although he has spoken about his relationship with Elle and the importance of his parents, the couple has not publicly revealed any plans regarding children.
Consequently, there is insufficient verified information to establish whether Jacob Misiorowski has children.
Jacob Misiorowski’s Parents: Meet Tom and Crystal Misiorowski
Jacob Misiorowski’s parents are Tom Misiorowski and Crystal Misiorowski, who raised him in the Grain Valley area of Missouri.
Both parents supported his interest in baseball from childhood and continued following his development through high school, college and professional competition.
Their commitment became particularly visible on June 12, 2025, when Jacob made his Major League Baseball debut for the Milwaukee Brewers.
Tom and Crystal traveled approximately seven hours from Missouri to Milwaukee to watch their son pitch against the St. Louis Cardinals.
More than 30 relatives and friends also attended the game, celebrating a milestone that had taken years of hard work to achieve.
Tom Misiorowski: Jacob Misiorowski’s Father
Tom Misiorowski is Jacob Misiorowski’s father and one of the most influential people in his life.
Tom previously worked as an electrician before being forced to retire early because of Parkinson’s disease.
He was diagnosed with the condition in 2014, when Jacob was still a young teenager.
Parkinson’s disease is a progressive neurological disorder that can affect movement, coordination and several other physical functions.
According to MLB.com, Tom has undergone medical treatments involving neurological devices to help manage the condition.
Although the diagnosis significantly changed the family’s circumstances, Tom remained closely involved in his son’s childhood and baseball development.
In an August 2025 interview, Jacob explained that his father’s early retirement allowed them to spend more time together during his teenage years.
However, he also acknowledged the considerable physical difficulties his father experienced.
Despite these challenges, Tom continued supporting Jacob’s baseball ambitions and remained present during important career moments.
The two also shared interests outside baseball, particularly collecting sports trading cards.
In an October 2026 MLB interview, Jacob recalled collecting baseball and football cards with his father during childhood.
That hobby eventually developed into Jacob’s well-known enthusiasm for Pokémon cards, which he continues collecting as a professional athlete.
How Jacob Misiorowski Honors His Father Tom’s Parkinson’s Battle
Jacob Misiorowski’s relationship with his father became a significant public story during his rookie season in 2025.
On June 25, 2025, the pitcher wore specially designed baseball cleats during a game against the Pittsburgh Pirates.
The footwear featured his father’s initials, “TM,” alongside a red tulip, a widely recognized symbol associated with Parkinson’s disease awareness.
The gesture was intended to honor Tom and encourage greater public understanding of the condition.
During an interview following the game, Jacob became emotional while discussing his father’s health and the importance of supporting families affected by Parkinson’s disease.
He explained that his father had experienced significant difficulties but continued finding ways to remain involved in his life.
In August 2025, Jacob announced a partnership with the Wisconsin Parkinson Association, an organization supporting individuals and families affected by the condition.
The partnership included fundraising activities, public awareness campaigns and opportunities for fans to contribute to charitable initiatives.
Jacob also participated in autograph-signing events organized to support the association.
His involvement continued into 2026, when the organization hosted another fundraising event featuring the Brewers pitcher.
His father’s experience has therefore become an important source of motivation for Jacob’s charitable work away from baseball.
Crystal Misiorowski: Jacob Misiorowski’s Mother
Crystal Misiorowski is Jacob Misiorowski’s mother and a dedicated supporter of his professional baseball career.
She raised Jacob alongside her husband, Tom, in Missouri and has remained closely involved throughout his development as an athlete.
Crystal became especially visible during her son’s Major League Baseball debut on June 12, 2025.
She traveled from Missouri to Milwaukee with Tom and watched from the stands as Jacob delivered an impressive performance against the St. Louis Cardinals.
During the game, Crystal participated in an interview with the Brewers’ television broadcast, discussing her son’s work ethic and the emotions surrounding his arrival in Major League Baseball.
She expressed pride in his dedication and the commitment required to reach the sport’s highest level.
Crystal has continued attending games throughout Jacob’s professional career.
In July 2026, Sports Illustrated reported that she had made an approximately eight-hour drive from the Kansas City area to Milwaukee to watch an important start against the Philadelphia Phillies.
After the game, she was seen accompanying Jacob, his fiancée, Elle, and Elle’s parents.
Brewers manager Pat Murphy publicly praised the family’s closeness and the positive influence of their support.
Although Crystal has appeared in several baseball-related interviews, detailed information about her occupation and educational background has not been widely documented in reliable sources.
Jacob Misiorowski’s Siblings: Does He Have Brothers or Sisters?
Information about Jacob Misiorowski’s siblings remains limited. As of now, reliable public sources have not confirmed whether the Milwaukee Brewers pitcher has brothers or sisters.
His official MLB biography identifies his father, Tom, but does not provide information about siblings.
Most established sports reports about his family focus on his parents, his fiancée and their involvement in his baseball career.
Although dozens of relatives and friends attended his MLB debut, the available reporting does not establish whether any of those individuals were his siblings.
It would therefore be inaccurate to describe Jacob as an only child or identify specific brothers or sisters without additional verified information.
His sibling relationships, if any, have not been publicly documented in sufficient detail.
Jacob Misiorowski’s Grandmother and Extended Family
Jacob Misiorowski has also shared meaningful experiences with members of his extended family, including his grandmother.
During his time at Crowder College in Neosho, Missouri, Jacob regularly visited his grandmother, who lived close enough for him to spend time with her away from baseball.
In an October 2026 MLB feature, his former college teammate Adamo Stornello recalled how Jacob frequently visited his grandmother for home-cooked meals and family time.
Those visits allowed him to maintain a connection to home while adjusting to the demands of college baseball.
Although his grandmother’s name was not provided in the report, her involvement reflects the importance of extended family relationships during Jacob’s development.
His fiancée’s parents have also become part of his support network, occasionally attending Milwaukee Brewers games alongside Crystal Misiorowski.
How Jacob Misiorowski’s Family Influenced His Baseball Career
Jacob Misiorowski’s family has played an important role in his development from a young athlete in Missouri to a Major League Baseball pitcher.
He attended Grain Valley High School, where he became one of the area’s most promising baseball players.
During his junior season in 2019, he recorded a 9-2 win-loss record with a 1.48 earned run average and received All-State recognition.
However, the COVID-19 pandemic interrupted his senior season in 2020.
Misiorowski initially committed to playing college baseball at Oklahoma State University but later decided to attend Crowder College in Missouri.
In an October 2026 interview with MLB.com, he explained that financial considerations influenced the decision because his family did not have the resources to comfortably meet the revised costs of his original college plans.
Attending Crowder College proved to be a turning point in his career.
During the 2022 season, he posted a 10-0 record with a 2.72 ERA and 136 strikeouts across 76 innings.
His performances attracted professional scouts, leading the Milwaukee Brewers to select him in the second round of the 2022 MLB Draft with the 63rd overall pick.
Misiorowski progressed through the organization’s minor league system before making his MLB debut on June 12, 2025.
He pitched five hitless innings against the St. Louis Cardinals, immediately attracting national attention.
He subsequently earned selection to the 2025 MLB All-Star Game after only five major league appearances.
His success continued in 2026, when he established himself as one of Milwaukee’s leading starting pitchers and helped the Brewers reach the World Series.
Throughout these achievements, his parents and fiancée have remained among the most important people supporting him away from the field.
