Keaton Winn Bio
Keaton Eugene Winn, born on February 20, 1998, in Ollie, Iowa, is an American professional baseball pitcher for the San Francisco Giants of Major League Baseball (MLB). Drafted by the Giants in the fifth round of the 2018 MLB draft out of Iowa Western Community College, Winn worked his way through the minor leagues before reaching the majors in 2023. Known for a mid-to-upper-90s fastball and a sharp splitter, he has developed into a notable arm in the Giants organization.
Standing out as a two-way player in his youth and an All-Conference pitcher in college, Winn’s path to professional baseball reflected perseverance after a major arm injury delayed his climb. His debut season included a memorable milestone that placed his name in the franchise record book, and he continues to build his career as a starting pitcher in San Francisco.
Early Life and Background
Keaton Eugene Winn was born to Chris and Lynn Winn in the small community of Ollie, Iowa. He grew up in rural Iowa, where athletics were a central part of life. He attended Pekin High School in Jefferson County, Iowa, graduating in 2016. The school’s baseball field, by his own account, used to be a corn field, a detail that captured the modest setting in which he first developed his game.
Winn was a multi-sport standout in high school, lettering in football, basketball, baseball, and track. He was a two-time All-State wide receiver and tight end in football and a two-time all-conference first team basketball player, setting a school single-game rebound record of 26 in 2014. On the track, he was part of a 4×200 meters relay state championship team in 2015. His diverse athletic background helped shape the competitive drive he would later bring to pitching.
Winn began playing varsity baseball for Pekin in eighth grade as a two-way player, contributing as a second baseman and a pitcher. In 2015, he threw a 20-strikeout perfect game, an early sign of his command on the mound. As a junior, he posted a 6-2 record with a 0.65 earned run average and 85 strikeouts in 53.2 innings, while batting .372 and going 9-for-9 in stolen bases. In his senior year, he struck out 66 batters in 33 innings, holding opponents to a .081 batting average.
Path to Professional Baseball
Following high school, Winn played college baseball at Iowa Western Community College in Council Bluffs, Iowa, suiting up for the Reivers. Over two seasons, he compiled a 9-2 record with five saves and a 2.37 earned run average across 31 games, including seven starts, while striking out 115 batters in 87.1 innings. He was recognized as a First-Team All-Iowa Community College Athletic Conference pitcher as a freshman. Scouts took notice of his mid-90s velocity and an above-average slider.
Winn was selected by the San Francisco Giants in the 20th round of the 2017 MLB draft but chose to return to Iowa Western for another season. The following year, the Giants drafted him again, this time in the fifth round with the 136th overall pick of the 2018 MLB draft. He signed with the club for an over-slot bonus of $500,000, formally launching his professional career.
Keaton Winn Career
Early Career (2018-2019)
Winn began his professional career in 2018 with the Low-A Salem-Keizer Volcanoes, going 3-1 with a 4.81 earned run average in 15 games, including five starts, while pitching 43 innings. The assignment allowed him to adjust to the pace of professional baseball and refine his secondary pitches.
In 2019, he advanced to the Single-A Augusta GreenJackets, where he turned in one of his strongest minor league seasons. Across 26 games and 20 starts covering 127.1 innings, he posted a 7-7 record and a 3.32 earned run average, good for fourth in the South Atlantic League. He allowed only 26 walks for a 1.8 walks per nine innings rate and posted a 1.17 WHIP, sixth-best in the league, demonstrating the control that had marked his career to that point.
Setbacks and Return (2020-2022)
Winn did not appear in any games in 2020 after the minor league season was canceled due to the COVID-19 pandemic. The following year, he underwent Tommy John surgery and missed the entire 2021 season, a significant setback that temporarily halted his development.
Winn returned to the mound midway through the 2022 season, splitting time between the Single-A San Jose Giants, the High-A Eugene Emeralds, and the Double-A Richmond Flying Squirrels. He finished the year with a combined 6-6 record and a 4.08 earned run average over 27 games and 25 starts, striking out 125 batters in 108 innings. His fastball velocity climbed into the upper 90s, and he added a plus mid-80s splitter to his arsenal. On November 15, 2022, the Giants added him to their 40-man roster to protect him from the Rule 5 draft.
Major League Debut and Rookie Season (2023)
Winn opened the 2023 season with the Triple-A Sacramento River Cats, where he went 0-3 with a 4.35 earned run average and 51 strikeouts in 41.1 innings across 12 games and nine starts. On June 12, 2023, he was promoted to the major leagues for the first time. He had never been to an MLB stadium until the day before his debut, an unusual twist for a player about to step onto a big-league mound.
Winn made his MLB debut on June 13, 2023, against the St. Louis Cardinals, working four innings and allowing one run on one hit while walking three and striking out two. His four-seam fastball reached 98.2 mph. He became the first Giants pitcher to earn a save in his major league debut since saves became an official statistic in 1969. Across his rookie campaign, he appeared in nine games with five starts, going 1-3 with a 4.68 earned run average, 35 strikeouts, and one save in 42.1 innings.
2024 Season and Injury
Winn began the 2024 season in the Giants’ starting rotation, posting a 3-8 record with a 7.16 earned run average and 48 strikeouts across 12 starts. He was placed on the injured list with a right forearm strain on May 17, 2024, and was transferred to the 60-day injured list on July 24. On July 26, the Giants announced that he would undergo season-ending ulnar nerve transposition surgery, sidelining him for the remainder of the year.
Return to the Majors (2025)
Winn was optioned to Triple-A Sacramento to begin the 2025 season, working his way back to the major league roster following his 2024 arm surgery. His reentry into the rotation reflected the organization’s continued confidence in his upside as a starter.
Driving Style and Strengths
Winn relies on a mid-to-upper-90s four-seam fastball that has touched 100 mph, pairing it with a splitter that scouts have described as a potential plus pitch. Manager Gabe Kapler praised the splitter as having a chance to be especially effective against major league hitters. He also features a slider, giving him a three-pitch mix built around swing-and-miss stuff and ground ball contact, with a 50.9 percent ground ball rate in Triple-A in 2023.
Notable Events and Milestones
Winn’s most memorable career moment came on June 13, 2023, when he became the first Giants pitcher to record a save in his major league debut since saves became an official statistic in 1969. He had never visited an MLB stadium before the day of that debut, making the milestone all the more striking. Earlier in his career, he threw a 20-strikeout perfect game as a high school pitcher in 2015, foreshadowing the strikeout ability he has shown at every subsequent level.

Minor League Highlights
Winn’s first professional season with the Salem-Keizer Volcanoes in 2018 produced a 3-1 record across 15 appearances. In 2019, he earned seven wins with the Augusta GreenJackets. His return from Tommy John surgery in 2022 yielded six wins across three levels of the minor leagues, and he added victories at the Triple-A level with Sacramento before his major league debut.
Major League Highlights

Keaton Winn Family
Family Background and Racing Lineage
Keaton Eugene Winn was raised by his parents, Chris and Lynn Winn, in the small town of Ollie, Iowa. His upbringing in rural Iowa, including playing on a baseball field that used to be a corn field, shaped his grounded approach to the game. Information about a broader family lineage in sports beyond his parents has not been publicly documented.
Personal Life
Winn has maintained a relatively private personal life, and details about a spouse, partner, or children have not been publicly disclosed. He is American by nationality and was raised in Iowa before pursuing his professional baseball career with the San Francisco Giants organization.
2025 Season Performance
Winn began the 2025 season with the Triple-A Sacramento River Cats, working to reestablish himself after undergoing ulnar nerve transposition surgery in July 2024. The assignment allowed him to rebuild arm strength and refine his command following a year in which he had posted a 7.16 earned run average in the majors before the injury. His progress at Triple-A was a key storyline for both player and club entering the new season.
Once recalled to the major league roster, Winn offered the Giants a starter with a power fastball and a developing splitter, two pitches that had defined his early big-league success. His 2023 debut, which included a franchise-record save in his first appearance, provided a reminder of the upside he brings to the rotation when healthy. Continued strikeout totals and improved control were central benchmarks for his 2025 campaign.
Looking ahead, Winn’s long-term outlook depends on his ability to stay healthy and translate his Triple-A results into consistent major league production. With a fastball that can reach triple digits and a splitter described as a potential out pitch, he has the tools to remain a part of San Francisco’s pitching plans. His development remains one of the more closely watched storylines within the Giants organization.
