Quinn Priester Bio
Charles Quinn Priester, known professionally as Quinn Priester, is an American professional baseball pitcher for the Milwaukee Brewers of Major League Baseball (MLB). He was selected by the Pittsburgh Pirates in the first round of the 2019 MLB draft and made his major league debut in 2023. Before establishing himself in the majors, Priester worked his way through the minor league system, drawing attention as one of Pittsburgh’s top pitching prospects. He has also appeared in MLB for the Boston Red Sox, who acquired him in a midseason trade in 2024 before flipping him to Milwaukee in 2025.
Early Life and Background
Charles Quinn Priester was born on September 15, 2000, in Cary, Illinois, and grew up in the Chicago suburbs. He attended Cary-Grove High School, where he was a multi-sport athlete. In addition to starring on the baseball diamond, Priester played football and was a member of the 2018 Cary-Grove football team that captured the 6A state championship, even catching a touchdown pass in the title game.
On the mound, Priester emerged as one of the top prep arms in the country. As a senior in 2019, he posted an 8-2 win-loss record with a 1.00 earned run average, striking out 91 batters in just over 60 innings of work. His dominant senior season earned him the Illinois Gatorade Baseball Player of the Year award. Following high school, he committed to play college baseball at Texas Christian University before opting to begin his professional career.
Path to Major League Baseball
The Pittsburgh Pirates selected Priester with the 18th overall pick of the 2019 MLB draft, signing him for $3.4 million. He was assigned to the rookie-level Gulf Coast League Pirates, where he went 1-1 with a 3.19 ERA and 41 strikeouts in roughly 36 innings. He did not see action in 2020 after the minor league season was canceled due to the COVID-19 pandemic, but he returned in 2021 to pitch for the High-A Greensboro Grasshoppers, going 7-4 with a 3.04 ERA and 98 strikeouts. That summer, he was selected to the All-Star Futures Game, a traditional showcase for baseball’s top young talent.
Over the next two seasons, Priester climbed Pittsburgh’s minor league ladder, splitting time between Single-A Bradenton, Greensboro, Double-A Altoona, and Triple-A Indianapolis. By 2023, he was ready for the major leagues, and Pittsburgh promoted him to the 40-man roster and called him up on July 17. He made his debut that day as the starting pitcher against the Cleveland Guardians, becoming one of the Pirates’ youngest arms to reach the big leagues in recent memory.
Quinn Priester Career
Early Career (2019-2022)
Priester began his professional career in the Gulf Coast League in 2019 and quickly established himself as a polished strike-throwing pitcher. His 41 strikeouts in nine appearances demonstrated the swing-and-miss stuff that had made him a first-round pick, even as he continued to develop secondary offerings. The canceled 2020 minor league season interrupted his momentum, but he returned with a strong 2021 campaign at High-A Greensboro.
In 2022, Priester bounced between four affiliates while continuing to build endurance and consistency. Across 19 starts at Single-A Bradenton, Greensboro, Double-A Altoona, and Triple-A Indianapolis, he posted a 5-5 record and a 3.29 ERA with 89 strikeouts. The variety of stops reflected Pittsburgh’s effort to challenge him at multiple levels, and he largely held his own against older competition.
Pittsburgh Pirates Era (2023-2024)
Priester opened 2023 at Triple-A Indianapolis and earned a 7-3 record with a 4.31 ERA before the Pirates promoted him in mid-July. His first major league start against the Cleveland Guardians was a learning experience, as he surrendered seven runs in 5⅓ innings. Over the rest of his rookie season, he struggled to a 7.74 ERA across 10 games and 8 starts, totaling 50 innings and 36 strikeouts.
He began 2024 back at Triple-A after losing the final rotation spot to Jared Jones, but the Pirates recalled him in April. In 10 appearances and 6 starts through the summer, he went 2-6 with a 5.04 ERA, walking 13 batters and giving up seven home runs in 44⅔ innings. On July 29, 2024, Pittsburgh traded him to the Boston Red Sox in exchange for infield prospect Nick Yorke, ending his time in the Pirates organization.
Boston Red Sox Era (2024-2025)
After the trade, the Red Sox assigned Priester to their Triple-A affiliate in Worcester, with the organization focusing on boosting his velocity. Boston’s pitching coaches believed his sinker needed to average 96 miles per hour to play at the top level. He was given the ball for Boston’s regular season finale against the Tampa Bay Rays, allowing one run on four hits with two strikeouts in five innings, a strong finish to his first year in the organization.
The Red Sox optioned Priester to Worcester to begin 2025 as he continued to refine his arsenal. Before the season could fully unfold, however, Boston dealt him again, this time to the Milwaukee Brewers on April 7, 2025, in exchange for minor-league outfielder Yophery Rodriguez, a Competitive Balance Round draft pick, and a player to be named later. The trade gave Priester a fresh start in a pitcher-friendly organization.
Milwaukee Brewers Era (2025-Present)
The change of scenery proved transformative. Beginning in mid-May 2025, Priester put together an eight-game stretch in which he posted a 2.23 ERA, a 5.6 percent walk rate, and a 60 percent groundball rate, the kind of numbers that quickly made him a reliable rotation piece. When Milwaukee promoted top prospect Jacob Misiorowski on June 12, the Brewers traded veteran Aaron Civale rather than using one of Priester’s minor league options, a sign of how much he had grown. By the end of July, he stood at 10-2 with a 3.27 ERA.
Priester’s most historic moment came on September 18, 2025, when an 8-2 victory over the St. Louis Cardinals gave him his 12th consecutive winning decision, surpassing the Milwaukee franchise mark previously shared by Chris Bosio and Cal Eldred at 10 straight wins in 1992. Earlier in that same start, he left a game against the Los Angeles Angels in the sixth inning with the score tied at 2-2, and the Brewers rallied for a 5-2 win, extending their streak to 19 consecutive victories in games he had appeared, another franchise record. His emergence has been one of the defining stories of Milwaukee’s 2025 campaign.
Driving Style and Strengths
Priester relies on a heavy sinker that he works to both sides of the plate, generating groundballs rather than chase swings. His mid-90s velocity, refined during his time in the Boston system, allows him to challenge hitters, while his breaking ball has become a reliable put-away pitch. Pairing that arsenal with a sharp command profile, he has emerged as a steadying presence in Milwaukee’s rotation.
Notable Events and Milestones
From his first-round selection in 2019 to his 2025 franchise-record winning streak, Priester’s career has featured several defining milestones. His All-Star Futures Game appearance in 2021, his MLB debut in Cleveland in July 2023, and his historic September 2025 run with the Brewers each marked a step forward in his development as a starter.

2025 Season Performance
Quinn Priester’s 2025 season began with the Boston Red Sox, who optioned him to Triple-A Worcester as he continued to build velocity. On April 7, the Red Sox traded him to the Milwaukee Brewers for Yophery Rodriguez, a Competitive Balance Round pick, and a player to be named later, giving Priester a fresh start in a pitcher-friendly organization.
That move quickly paid off. From mid-May onward, Priester turned in an eight-game stretch with a 2.23 ERA, a 5.6 percent walk rate, and a 60 percent groundball rate, numbers that helped him lock down a rotation spot. When Milwaukee promoted top pitching prospect Jacob Misiorowski in mid-June, the Brewers chose to trade veteran Aaron Civale rather than use one of Priester’s minor league options, a strong endorsement of his progress. By the end of July, he was 10-2 with a 3.27 ERA.
The defining stretch came in September. On September 18, 2025, an 8-2 win over the St. Louis Cardinals gave him his 12th consecutive winning decision, breaking the Brewers franchise record shared by Chris Bosio and Cal Eldred. With the Brewers firmly in the playoff picture and Priester turning in the best work of his career, his 2025 outlook points toward a key postseason role.
