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 after progressing through the minor league systems of the Colorado Rockies and Milwaukee organizations. Collins bats left-handed and is recognized for a contact-oriented approach paired with reliable outfield defense.
A graduate of Creighton University and a native of Minnesota, Collins reached the majors as a position-player prospect whose game leaned on plate discipline and baserunning. In his first full MLB campaign, he earned recognition as a top National League rookie, including National League Rookie of the Month and National League Player of the Week honors, before being traded to the Kansas City Royals during the 2025-2026 offseason.
Early Life and Background
Isaac Michael Collins was born on July 22, 1997, in Maple Grove, Minnesota. He grew up in the Twin Cities suburb and attended Maple Grove Senior High School, from which he graduated in 2016. During his high school years he developed into a multi-sport athlete and emerged as a college baseball prospect with a left-handed swing and the speed to play a premium outfield position.
After high school, Collins enrolled at Creighton University in Omaha, Nebraska, where he played college baseball for the Creighton Bluejays. He continued his development during the college summers, playing collegiate summer baseball for the Duluth Huskies of the Northwoods League in 2017 and for the Wareham Gatemen of the Cape Cod Baseball League in 2018. Those summer leagues gave him regular at-bats against high-level amateur competition and helped refine his approach at the plate.
Path to Baseball
After his junior season at Creighton, Collins entered the 2019 Major League Baseball draft, where the Colorado Rockies selected him in the ninth round with the 279th overall pick. He made his professional debut that summer with the Low-A Boise Hawks, hitting .257 with 17 runs batted in over 37 games in the short-season Northwest League.
Collins did not appear in a game in 2020 after the minor league season was canceled because of the COVID-19 pandemic. He returned in 2021 and split the year between the Single-A Fresno Grizzlies and the High-A Spokane Indians, combining for a .308/.407/.475 batting line with nine home runs, 54 runs batted in, and 21 stolen bases across 95 games. The production showed the kind of on-base skills and speed that clubs look for in a table-setter, and he advanced to Double-A Hartford in 2022 to test himself against more experienced pitching.
Isaac Collins Career
Early Career (2019-2022)
Collins spent his first three professional seasons in the Colorado Rockies organization, moving steadily from Low-A Boise to High-A Spokane and then to Double-A Hartford. Across his developmental years he showed a patient approach at the plate and the baserunning ability to pressure defenses, finishing 2022 with the Yard Goats by playing 111 games and batting .221/.337/.347 with five home runs, 32 runs batted in, and 30 stolen bases.
The Rockies left Collins exposed in the minor league phase of the Rule 5 draft following the 2022 season, and on December 7, 2022, the Milwaukee Brewers selected him to add depth to their farm system. The trade of his contract effectively launched the next phase of his career, giving him a new organization and a clearer runway toward the major leagues.
Milwaukee Brewers Breakthrough (2023-2025)
Collins opened his Brewers tenure in 2023 with the Double-A Biloxi Shuckers, slashing .269/.424/.431 with 10 home runs, 44 runs batted in, and 29 stolen bases across 93 games, and he finished the year with a brief three-game stint at Triple-A Nashville. The on-base skills that had marked his amateur profile carried into the upper minors, and Milwaukee moved him into a larger role at Nashville in 2024.
In 2024 Collins spent the bulk of the season at Triple-A Nashville, where he hit .273/.386/.475 and set career highs with 14 home runs and 76 runs batted in over 113 games. On September 8, 2024, the Brewers added him to the 40-man roster and promoted him to the majors for the first time. In 11 September appearances he went 2-for-17 with one stolen base and two walks, completing his first taste of MLB action.
The 2025 season was Collins’s true breakthrough. On April 30, 2025, he hit his first career home run 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 (.321) with four stolen bases and eleven walks. On August 10, Collins delivered a walk-off home run off Edwin Diaz to beat the New York Mets 7-6 at American Family Field, and the following day he was named the National League Player of the Week for August 4-10, a stretch in which he batted .476 with six runs, two home runs, eight runs batted in, and a 1.529 OPS. He finished the year with 130 appearances for Milwaukee, slashing .263/.368/.411 with nine home runs, 54 runs batted in, and 16 stolen bases, and on November 12 he was named to MLB Pipeline’s 2025 All-Rookie First Team.
Kansas City Royals Era (2026-Present)
On December 14, 2025, Collins was traded, along with pitcher Nick Mears, to the Kansas City Royals in exchange for pitcher Ángel Zerpa. The deal gave Kansas City a controllable left-handed outfielder coming off a strong rookie season and gave Collins a fresh opportunity in a new organization.
Wearing No. 1 for the Royals, Collins opened his Kansas City tenure playing left field and working in the middle of the batting order. Through the early portion of the season his batting line stood at .246 with 12 home runs and 77 runs batted in, a power surge that represented a clear step forward from his production with Milwaukee. The Royals viewed him as a building block for their outfield, and Collins responded by becoming a regular in the everyday lineup.
Driving Style and Strengths
Collins is a left-handed hitter whose game is built around plate discipline, contact, and baserunning pressure rather than raw power. He draws walks at a high rate, uses the whole field, and has consistently graded as an above-average runner, which translates into extra-base hits on the bases and range in the outfield. Defensively, his reads and routes in left field have made him a steady presence, and his ability to play all three outfield spots gives his manager flexibility.
Notable Events and Milestones
His first major league home run off Tyler Gilbert of the Chicago White Sox on April 30, 2025, marked the beginning of his power surge as a rookie. The walk-off home run against the Mets on August 10, 2025, off closer Edwin Diaz, became one of the defining moments of Milwaukee’s season. He was also named National League Rookie of the Month for July 2025, National League Player of the Week for August 4-10, 2025, and to MLB Pipeline’s 2025 All-Rookie First Team.
