Keaton Winn Bio
Keaton Eugene Winn (born February 20, 1998) is an American professional baseball pitcher for the San Francisco Giants of Major League Baseball (MLB). A native of small-town Ollie, Iowa, Winn played college baseball at Iowa Western Community College in Council Bluffs, Iowa, before being drafted by the Giants in the fifth round of the 2018 MLB draft. He made his Major League Baseball debut on June 13, 2023, against the St. Louis Cardinals, and became the first Giants pitcher since saves became an official statistic in 1969 to earn a save in his major league debut.
Early Life and Background
Keaton Eugene Winn was born on February 20, 1998, in Ollie, Iowa, to Chris and Lynn Winn. Growing up in a small farming community, he attended Pekin High School in Jefferson County, Iowa, where he emerged as one of the most versatile multisport athletes in the region. Beyond baseball, Winn was a two-time All-State wide receiver and tight end in football, a two-time all-conference first-team basketball player who set the school’s all-time single-game rebound record with 26 rebounds in 2014, and a 4 × 200 meters relay state champion in track in 2015.
Winn began playing varsity baseball for Pekin as an eighth-grader, competing on a baseball field that he and his teammates recalled had once been a corn field. As a two-way player, he pitched a 20-strikeout perfect game in 2015 while also playing second base. During his junior year, he posted a 6–2 win–loss pitching record with a 0.65 earned run average (ERA) in 53.2 innings, walking 11 batters while striking out 85 and holding opponents to a .067 batting average. He also hit .372/.430/.564 as a batter that season and went a perfect 9-for-9 in stolen bases. His senior year saw him go 3–1 on the mound with 66 strikeouts in 33 innings and a .413/.500/.714 line at the plate, along with a 16-for-16 record in stolen bases.
Path to Baseball
After graduating from Pekin High School, Winn took his game to Iowa Western Community College, where he pitched for the Reivers over two seasons. In 31 appearances covering 7 starts, he compiled a 9–2 record with five saves, a 2.37 ERA, and 115 strikeouts across 87.1 innings, earning First-Team All-Iowa Community College Athletic Conference honors as a freshman. He routinely pitched in the mid-90s and showed off an above-average slider that hinted at his future projection as a professional arm.
The San Francisco Giants selected Winn in the 20th round of the 2017 MLB draft, but he opted to return to Iowa Western for one more season to refine his skills. The decision paid off when the Giants picked him again in 2018, this time in the fifth round with the 136th overall selection, and signed him for an over-slot $500,000 signing bonus.
Keaton Winn Career
Early Career (2018–2019)
Winn began his professional career in 2018 with the Low-A Salem-Keizer Volcanoes, where he went 3–1 with a 4.81 ERA in 15 appearances and 5 starts, covering 43 innings. The following year, he advanced to the Single-A Augusta GreenJackets and broke out with a 7–7 record and a 3.32 ERA in 26 games and 20 starts. Across 127.1 innings, he allowed only 26 walks (1.8 walks per 9 innings) and posted a 1.17 WHIP, marks that ranked among the best in the South Atlantic League and signaled his growing command.
Minor League Development (2022)
After missing the 2020 season when the minor league schedule was canceled because of the COVID-19 pandemic, and sitting out all of 2021 following Tommy John surgery, Winn returned to the mound in 2022. Splitting the year between Single-A San Jose, High-A Eugene, and Double-A Richmond, he went a combined 6–6 with a 4.08 ERA in 27 games and 25 starts, striking out 125 batters in 108 innings. His velocity climbed into the upper 90s and he added a plus mid-80s splitter to his arsenal, prompting the Giants to add him to their 40-man roster on November 15, 2022, to protect him from the Rule 5 draft.
MLB Debut and Rookie Season (2023)
Winn opened 2023 with the Triple-A Sacramento River Cats, going 0–3 with a 4.35 ERA, 51 strikeouts, and an 11.1 strikeouts-per-nine-innings rate across 12 appearances and 9 starts. On June 12, 2023, the Giants promoted him to the majors for the first time, even though the 25-year-old had never in his life been to a Major League Baseball stadium until shortly before his call-up.
Making his MLB debut on June 13 against the St. Louis Cardinals, Winn allowed one run on one hit over four innings, walking three and striking out two while touching 98.2 mph with his four-seam fastball. He became the first Giants pitcher to record a save in his major league debut since saves became an official statistic in 1969. Across his rookie campaign, he made 9 appearances with 5 starts, finishing 1–3 with a 4.68 ERA, 35 strikeouts, one save, and 42.1 innings pitched.
San Francisco Giants Era (2024–Present)
Winn opened the 2024 season in the Giants’ rotation but struggled to a 3–8 record and a 7.16 ERA with 48 strikeouts over 12 starts. A right forearm strain landed him on the injured list on May 17, 2024, and he was moved 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. The Giants optioned him back to Triple-A Sacramento to begin the 2025 season as he worked his way back.
Driving Style and Strengths
Winn attacks hitters with a mid-to-upper-90s fastball that has touched 100 mph, paired with a sharp splitter that manager Gabe Kapler described as having a chance to be “really evil,” along with a competent slider. His strikeout rate at Triple-A in 2023 (11.1 per nine innings) and a 50.9% ground-ball rate point to a power profile built on swings and misses and weak contact.
Notable Events and Milestones
Winn’s MLB debut on June 13, 2023, against the St. Louis Cardinals stands as his signature moment to date, headlined by becoming the first Giants pitcher to earn a save in his major league debut in the saves era. He also touched 98.2 mph with his four-seamer in that appearance and earned high praise from manager Gabe Kapler, who said, “He’s going to be good. He’s got a chance to be even better than he was tonight.”
Keaton Winn Career Wins
Across his professional career, Keaton Eugene Winn has compiled a growing ledger of wins that stretches from the Low-A Salem-Keizer Volcanoes through Triple-A Sacramento and into the San Francisco Giants’ Major League rotation.

Minor League Highlights
Winn’s combined 9–2 record at Iowa Western Community College included five saves, and he added a 3–1 mark at Salem-Keizer in 2018 before a 7–7 season at Augusta in 2019 that placed him among the South Atlantic League leaders in ERA. After missing two full seasons, he returned in 2022 with a 6–6 line across three affiliates, striking out 125 batters in 108 innings.

2025 Season Performance
Keaton Eugene Winn began the 2025 season with the Triple-A Sacramento River Cats as he continued his return from the July 2024 ulnar nerve transposition surgery. The Giants optioned him to Sacramento to build up innings and recapture the upper-90s velocity that defined his 2023 debut. His progression in the Pacific Coast League is expected to determine the timing of any return to the San Francisco rotation.
For Winn, the 2025 storyline centers on health, command, and reestablishing the splitter-fastball combination that made him a Rule 5-protected prospect. With Triple-A as his runway, his goal is to put together a string of healthy outings and rejoin the Giants’ major league staff with a fully built-up arm.
Looking ahead, Winn’s outlook for the rest of 2025 hinges on how quickly his stuff returns and whether the Giants need a rotation reinforcement. If his velocity and splitter return to pre-surgery form, he has a clear path back to the San Francisco bullpen or rotation and a chance to build on his historic 2023 debut.
