Keaton Eugene Winn Career
Professional Career Beginnings (2017–2018)
The San Francisco Giants first selected Winn in the 20th round of the 2017 MLB Draft. Opting to return to Iowa Western for another season to further develop his skills, he became a more polished prospect. The following year, the Giants drafted him again in the fifth round with the 136th overall selection in the 2018 MLB Draft, signing him to an over-slot signing bonus of $500,000.
Winn began his professional career in 2018 with the Low-A Salem-Keizer Volcanoes, where he appeared in 15 games with a 3–1 record and a 4.81 ERA across 43 innings pitched. The following season, he advanced to Single-A Augusta GreenJackets and experienced significant success, posting a 7–7 record with a 3.32 ERA that ranked fourth in the South Atlantic League.
Minor League Development and Setbacks (2019–2022)
At Augusta, Winn pitched 127 and one-third innings with only 26 walks, demonstrating exceptional control with a 1.17 WHIP that ranked sixth in the league. His ability to limit baserunners while missing bats established him as a promising pitching prospect within the Giants organization.
The 2020 season was lost entirely due to the COVID-19 pandemic, which canceled the minor league schedule. More significantly, Winn underwent Tommy John surgery prior to the 2021 campaign, forcing him to miss the entire season. This injury setback required nearly three years of rehabilitation and recovery before he could return to competitive pitching.
Winn returned to the mound midway through the 2022 season, appearing for three affiliates within the Giants system. Pitching for the Single-A San Jose Giants, High-A Eugene Emeralds, and Double-A Richmond Flying Squirrels, he combined to go 6–6 with a 4.08 ERA across 108 innings, striking out 125 batters. Notably, his velocity returned stronger than before, reaching the upper 90s, and he developed a plus mid-80s splitter. His performance earned him a spot on the Giants’ 40-man roster on November 15, 2022, protecting him from the Rule 5 Draft.
San Francisco Giants Era (2023–Present)
Winn began the 2023 season with Triple-A Sacramento River Cats, where he posted a 0–3 record with a 4.35 ERA and 51 strikeouts across 41 and one-third innings. His stuff drew praise from management, with Giants manager Gabe Kapler describing his split-finger fastball as having a chance to be “really evil.” On June 12, 2023, Winn received his first major league call-up.
He made his MLB debut on June 13 against the St. Louis Cardinals, pitching four innings while allowing one run on one hit, walking three batters, and striking out two. His four-seam fastball reached 98.2 mph. In a remarkable achievement, Winn recorded a save in his debut, becoming the first Giants pitcher since 1969 to accomplish this feat. Manager Gabe Kapler commented that Winn had the potential to be even better than his debut performance suggested. He finished his rookie season with a 1–3 record, 4.68 ERA, 35 strikeouts, and one save across 42 and one-third innings in nine appearances.
The 2024 season presented significant challenges for Winn. He began the year in San Francisco’s starting rotation but struggled to find consistency, compiling a 3–8 record with a 7.16 ERA through 12 starts. The Giants placed him on the injured list on May 17 with a right forearm strain, and he was transferred to the 60-day injured list on July 24. The injury required season-ending ulnar nerve transposition surgery, announced on July 26, which ended his campaign prematurely.
Winn entered the 2025 season with a new opportunity, optioned to Triple-A Sacramento to begin the year as he worked to return to major league form following his recovery from surgery.
Pitching Style and Strengths
Winn features a mid-to-upper-90s fastball that has reached 100 mph, giving hitters limited time to react at the plate. His primary secondary weapon is a split-finger fastball that has earned praise from coaches for its effectiveness, with manager Gabe Kapler noting its potential to be “nasty” and “really evil.” He also throws a slider that has shown above-average potential. His ability to generate ground balls, posting a 50.9% ground ball rate during his time at Sacramento, provides his defense with opportunities for double plays and limits extra-base hits.
Notable Events and Milestones
Winn’s major league debut on June 13, 2023, stands as the defining moment of his early career. Not only did he earn his first major league victory opportunity, but he also recorded a save, joining an exclusive group as the first Giants pitcher to accomplish this in a debut since saves became an official statistic in 1969. Remarkably, Winn had never visited a major league stadium until one day before his debut, highlighting the rapid rise of the Iowa native from small-town baseball to the highest level of the sport.
