C.J. Kayfus Bio
Collin Joseph Kayfus, commonly known as C.J. Kayfus, is an American professional baseball player who serves as a first baseman and outfielder for the Cleveland Guardians of Major League Baseball (MLB). Born on October 28, 2001, he made his Major League debut in 2025 after progressing through the Guardians’ farm system. A product of the 2023 MLB Draft, Kayfus is regarded as a young position player whose bat has carried him quickly through the minor leagues.
Standing out as a position-playing prospect out of South Florida, Kayfus combines outfield athleticism with the ability to handle first base. His rapid promotion through Cleveland’s developmental ranks reflects the organization’s confidence in his offensive profile and overall baseball instincts. He has already become a name to watch in the Guardians’ long-term plans.
Early Life and Background
Kayfus grew up in Wellington, Florida, a community in Palm Beach County known for producing competitive amateur baseball talent. He attended Palm Beach Central High School, where he developed as a position player and drew early attention from college recruiters. The Florida climate and year-round baseball culture of the region gave him a steady platform to refine his swing and defensive skills.
Coming from a supportive background, Kayfus was able to pursue competitive baseball throughout his teenage years. Wellington’s youth and travel baseball circuits helped him build the kind of game experience that prepared him for high school varsity competition and, eventually, college recruitment from prominent programs along the East Coast and Southeast.
Path to Baseball
After completing his time at Palm Beach Central High School, Kayfus committed to the University of Miami, one of the premier college baseball programs in the country. At Miami, he faced top-tier collegiate pitching and developed the consistency at the plate that would later make him an attractive professional prospect. His three years in the Hurricanes program helped shape his plate discipline and approach against high-level arms.
During the summer of 2021, Kayfus played collegiate summer baseball with the Wisconsin Woodchucks of the Northwoods League, a respected wooden-bat league that gives college players exposure to pro-style competition. The following summer, in 2022, he joined the Cotuit Kettleers of the Cape Cod Baseball League, widely considered the most prestigious summer league in collegiate baseball. Kayfus was named a Cape Cod League all-star that season, validating his status as one of the top hitters in the amateur ranks and setting the stage for the 2023 MLB Draft.
C.J. Kayfus Career
Early Career (2023)
The Cleveland Guardians selected Kayfus in the third round of the 2023 Major League Baseball draft, formalizing his transition from the amateur ranks to professional baseball. He signed with the organization and was assigned to the Lynchburg Hillcats, the Guardians’ Low-A affiliate, where he made his professional debut. The Lynchburg assignment served as his introduction to the daily demands of a full professional season, including longer schedules, extended travel, and a more advanced scouting environment.
Across his first professional campaign, Kayfus focused on adjusting to wooden-bat competition on a full-season basis and building a foundation in the Guardians’ player development system. His time at Lynchburg gave Cleveland’s coaching staff an early look at his swing decisions, defensive versatility, and overall baseball IQ.
Minor League Progression (2024)
Kayfus began the 2024 season with the Lake County Captains, Cleveland’s High-A affiliate, where he continued to sharpen his offensive approach against more experienced pitching. The early portion of the year provided him the opportunity to face left-handed specialists and refine his timing against breaking balls, both of which are critical for a corner-position prospect.
His production with Lake County earned him a midseason promotion to the Akron RubberDucks, Cleveland’s Double-A affiliate. The jump to Double-A represented a significant step in competition level, and Kayfus handled the transition by maintaining his offensive identity while adjusting to the increased velocity and sharper command of upper-minor-league arms. The promotion reinforced the Guardians’ view of him as a legitimate corner-infield and outfield prospect.
Triple-A and MLB Breakthrough (2025)
Kayfus started the 2025 season back at Akron before being promoted to the Columbus Clippers, Cleveland’s Triple-A affiliate, in April. The Clippers assignment placed him one step away from the Major Leagues and gave him regular at-bats against pitchers who had already logged big-league time. His performance at Columbus kept him firmly on the Guardians’ radar as a near-term option at the highest level.
On August 2, 2025, the Guardians selected Kayfus to the 40-man roster and promoted him to the major leagues for the first time. He debuted the same day against the Minnesota Twins, marking the realization of a journey that began on the fields of Wellington and moved through Miami, Wisconsin, Cape Cod, and four levels of the minor leagues. Less than a week later, on August 9, 202fus hit his first Major League home run off Bryan Hudson of the Chicago White Sox, an early signature moment in his young big-league career.
Notable Events and Milestones
Kayfus’s most prominent milestone to date is his August 2, 2025 MLB debut against the Twins, followed quickly by his first Major League home run on August 9 off Bryan Hudson of the Chicago White Sox. His Cape Cod League all-star selection in 2022 stands as his most decorated amateur achievement, and his third-round selection in the 2023 MLB Draft confirmed his standing among the top college position players of that class.
C.J. Kayfus Career Wins
Kayfus’s early career has been defined more by developmental achievements and milestones than by traditional win-loss statistics, given his position as a position player. His recognition as a Cape Cod League all-star in 2022 and his rapid climb through four minor-league affiliates within roughly two professional seasons highlight the consistent production that has driven his ascent.
Minor League Highlights
Kayfus debuted professionally with the Lynchburg Hillcats in 2023 and quickly advanced through Cleveland’s system, moving from the Lake County Captains to the Akron RubberDucks in 2024 and reaching the Columbus Clippers in April 2025. His promotion to the majors on August 2, 2025, capped a minor-league arc that saw him progress one level at a time while handling increasingly difficult competition.
Other Wins & Performances
His selection as a Cape Cod League all-star in 2022 with the Cotuit Kettleers stands as the clearest pre-professional performance benchmark, and his third-round draft placement in 2023 reflects the high regard in which scouts held his offensive game coming out of the University of Miami.

Publicly available information about his immediate family, marital status, and personal relationships has not been widely reported, and specific details have therefore been omitted to avoid speculation.
2025 Season Performance
The 2025 season has been the defining year of Kayfus’s professional career to date. He opened the year at Double-A Akron before a quick promotion to Triple-A Columbus in April, where his bat continued to produce against upper-level pitching. The strong start at Columbus kept him in the conversation for a Major League opportunity as the Guardians evaluated their roster needs and looked for offensive upgrades.
That opportunity arrived on August 2, 2025, when Cleveland selected his contract and promoted him to the major leagues, inserting him into the lineup the same day against the Twins. A week later, he launched his first big-league home run off Bryan Hudson of the Chicago White Sox, an early indicator that his power has translated to Major League pitching. His first week in the majors offered a glimpse of the offensive profile that had driven his climb through the minors.
Looking ahead through the rest of the 2025 season, Kayfus enters a critical evaluation window as the Guardians assess his role for the future. Continued offensive production, defensive versatility between first base and the outfield, and adjustments to big-league pitching will shape his standing in Cleveland’s long-term plans. His trajectory from Wellington high school fields to an MLB debut within roughly three years underscores why the Guardians view him as a young player worth investing in.
