Early Life and Education of Will Klein
William “Will” Boone Klein was born on November 28, 1999, in Bloomington, Indiana. He grew up in his hometown and attended Bloomington High School North. During his high school years, Klein was a multi-positional player, spending time as a catcher before focusing more on pitching. A broken thumb in his senior year limited his time on the mound, but he still managed to post impressive numbers, striking out 30 batters in just 17 and two-thirds innings with a 1.98 ERA. His academic achievements were also notable, as he took several honors classes and achieved a high score of 34 on his ACT, which played a role in his college recruitment.
After graduating from high school in 2017, Klein enrolled at Eastern Illinois University to play college baseball for the Panthers. His transition to collegiate baseball presented some challenges, with his first two seasons yielding ERAs over 5.00. However, he showed significant improvement in his junior year in 2020, moving into the starting rotation and posting a 3.33 ERA with 33 strikeouts before the season was cut short due to the COVID-19 pandemic. This strong performance, showcasing a fastball in the high 90s, caught the attention of MLB scouts and established him as a promising prospect.
Will Klein’s Career
Will Klein’s professional baseball career was set in motion when he was selected by the Kansas City Royals in the fifth round of the 2020 Major League Baseball draft, with the 135th overall pick. He signed with the team for a $200,000 bonus. In 2021, Klein made his professional debut with the Quad Cities River Bandits, the High-A affiliate of the Royals. In his first season, he excelled as a reliever, recording a 7-1 win-loss record with a 3.20 ERA and an impressive 121 strikeouts over 70 and one-third innings. This stellar performance earned him the Royals’ Pitching Prospect of the Year award from MLB Pipeline.
The following year, Klein’s progress was hampered by shin splints, which delayed the start of his 2022 season. He spent the season with the Double-A Northwest Arkansas Naturals, where he struggled with his control, leading to a higher ERA. He returned to the Naturals to begin the 2023 season and showed improvement, which led to a promotion to the Triple-A Omaha Storm Chasers in mid-June. His strong performance in the minor leagues that year earned him a selection to represent the Royals at the 2023 All-Star Futures Game. In November 2023, the Royals added him to their 40-man roster to protect him from the Rule 5 draft.
Klein began the 2024 season with the Omaha Storm Chasers but was called up to the major leagues for the first time on April 25, 2024. He made his MLB debut on April 28 against the Detroit Tigers, striking out two batters in a scoreless inning. He recorded his first major league win a month later against the San Diego Padres. In July 2024, Klein was traded to the Oakland Athletics, where he made a few appearances before being designated for assignment in early 2025. He then had a brief stint with the Seattle Mariners organization in 2025, pitching for their Triple-A affiliate in Tacoma before being released in May.
On June 2, 2025, the Los Angeles Dodgers acquired Klein, a move that would prove to be a turning point in his career. He joined the Dodgers’ bullpen and quickly made an impact. His most notable performance came during Game 3 of the 2025 World Series, where he delivered a remarkable four-inning relief appearance, allowing only one hit and striking out five batters over 72 pitches in a marathon extra-inning game. This heroic effort was instrumental in the Dodgers’ victory and instantly elevated his status among fans and the baseball community.
