Isaac Collins Bio
Isaac Michael Collins is an American professional baseball left fielder who plays in Major League Baseball (MLB) for the Kansas City Royals. He previously played in MLB for the Milwaukee Brewers and made his major league debut in 2024. A native of Minnesota, Collins played college baseball at Creighton University before beginning his professional career in the Colorado Rockies organization. Across his minor league journey and his first major league seasons, he has built a reputation as a contact-oriented hitter with strong plate discipline and speed on the base paths.
Early Life and Background
Isaac Michael Collins was born on July 22, 1997, in Maple Grove, Minnesota. He grew up in the Minneapolis suburbs, where he attended Maple Grove Senior High School and graduated in 2016. During his high school years, Collins developed his baseball skills in a competitive Minnesota amateur scene and drew the attention of college recruiters with his combination of speed, hitting ability, and outfield instincts.
After high school, Collins enrolled at Creighton University, where he played college baseball for the Creighton Bluejays. He spent his summers sharpening his game in premier collegiate wooden-bat leagues, playing for the Duluth Huskies of the Northwoods League in 2017 and the Wareham Gatemen of the Cape Cod Baseball League in 2018. Those summer experiences exposed him to high-level competition and helped prepare him for a professional career.
Path to Baseball
Following his junior season at Creighton, Collins entered the 2019 Major League Baseball draft and was selected by the Colorado Rockies in the ninth round, with the 279th overall pick. He made his professional debut that summer with the Low-A Boise Hawks, posting a .257 batting average with 17 runs batted in over 37 games. The 2020 minor league season was canceled because of the COVID-19 pandemic, and Collins did not appear in a game that year.
He returned to action in 2021 and split the year between the Single-A Fresno Grizzlies and the High-A Spokane Indians. Across 95 games, Collins batted .308 with a .407 on-base percentage, .475 slugging percentage, nine home runs, 54 runs batted in, and 21 stolen bases. The 2022 season saw him promoted to the Double-A Hartford Yard Goats, where he played 111 games and batted .221 with five home runs, 32 runs batted in, and 30 stolen bases, demonstrating his speed and on-base skills even as his average dipped.
Isaac Collins Career
Early Career (2019–2022)
Collins began his climb through the Colorado Rockies system in 2019 with Boise, showing the offensive profile that would define his early career. His 2021 split between Fresno and Spokane was his first full professional season and produced his most well-rounded minor league line, blending power, patience, and speed. The 2022 campaign at Hartford provided his first extended look at Double-A pitching and gave him experience playing in the Eastern League.
On December 7, 2022, Collins was selected by the Milwaukee Brewers in the minor league phase of the Rule 5 draft, opening a new chapter in his development. He spent the 2023 season with the Double-A Biloxi Shuckers, batting .269 with a .424 on-base percentage, 10 home runs, 44 runs batted in, and 29 stolen bases over 93 games. He also received a brief three-game promotion to the Triple-A Nashville Sounds at the end of the year.
Milwaukee Brewers (2024–2025)
Collins opened the 2024 season with Nashville and turned in a strong year, batting .273 with a .386 on-base percentage, 14 home runs, and 76 runs batted in across 113 games, setting new career highs in power production. On September 8, 2024, the Brewers selected him to the 40-man roster and promoted him to the major leagues for the first time. In 11 late-season appearances with Milwaukee, he went 2-for-17 with one stolen base and two walks as he adjusted to big-league pitching.
The 2025 season marked Collins’s first full year in the majors and his true breakthrough. On April 30, 2025, he hit his first career home run, a memorable shot off Tyler Gilbert of the Chicago White Sox. He was later named the National League Rookie of the Month for July after going 25-for-78 with four stolen bases and 11 walks. On August 10, he delivered a walk-off home run off Edwin Diaz to give the Brewers a 7-6 victory over the New York Mets at American Family Field, and he was named the National League Player of the Week for August 4–10 after batting .476 with two home runs, eight runs batted in, and an OPS of 1.529. On November 12, 2025, he was named to MLB Pipeline’s 2025 All-Rookie First Team.
Kansas City Royals Era (2025–Present)
On December 14, 2025, Collins was traded, along with Nick Mears, to the Kansas City Royals in exchange for pitcher Ángel Zerpa. The move positioned the young outfielder in a new organization with an opportunity to take on a regular role in the major league outfield. He joined a Royals club looking to blend emerging talent with established veterans as it prepared for the upcoming season.
For Collins, the trade represented a fresh start following a rookie year in which he posted an OPS of 1.529 during his award-winning week and showed he could deliver in high-leverage moments. His combination of on-base skills, pop, and stolen-base ability fit the profile of an everyday contributor, and his transition to Kansas City set the stage for a full first season with his new club.
Driving Style and Strengths
As a left fielder, Collins relies on a balanced offensive game built around plate discipline, contact, and speed. He has consistently posted strong on-base percentages throughout his minor league career, and his stolen base totals at every level highlight his ability to affect the game on the base paths. His 2025 performance in Milwaukee showed the added dimension of power, particularly against left-handed relief pitching in late-inning spots.
Notable Events and Milestones
Among Collins’s signature moments are his first career home run on April 30, 2025, and his walk-off home run against the New York Mets on August 10, 2025. He was recognized as the National League Rookie of the Month for July 2025 and the National League Player of the Week for August 4–10, 2025, and he was selected to MLB Pipeline’s 2025 All-Rookie First Team.
