BIOGRAPHY
Keaton Winn was born on February 20, 1998, in Ollie, Iowa. He is a pitcher in the MLB.
Winn was selected by the San Francisco Giants in the 20th round of the 2017 MLB draft, but he decided to return to Iowa Western for one more season. The following year, he was drafted by the Giants again, this time in the fifth round of the 2018 MLB draft, and signed for an over-slot $500,000 signing bonus.
In 2018, pitching for the Low-A Salem-Keizer Volcanoes, Winn was 3–1 with a 4.81 ERA in 15 games (5 starts) during which he pitched 43 innings. In 2019, pitching for the Single–A Augusta GreenJackets, he was 7–7 with a 3.32 ERA (4th in the South Atlantic League) in 26 games (20 starts) in which he pitched 127.1 innings and allowed only 26 walks (1.8 walks per 9 innings) with a 1.17 WHIP (6th).
Winn did not play in a game in 2020 due to the cancellation of the minor league season because of the COVID-19 pandemic. Winn had Tommy John surgery prior to the 2021 season and missed the entire year.
In 2022, returning to pitching midway through the season after nearly three years away from the game, he played for the Single-A San Jose Giants, the High-A Eugene Emeralds, and the Double-A Richmond Flying Squirrels. He had a combined 6–6 record with a 4.08 ERA in 27 games (25 starts) during which he pitched 108 innings and struck out 125 batters. Winn's velocity reached the upper-90s, and he threw a plus mid-80s splitter. On November 15, 2022, the Giants added Winn to their 40-man roster to protect him from the Rule 5 draft.
Winn was optioned to the Triple-A Sacramento River Cats to begin the 2023 season. In 12 games (9 starts) for the River Cats, Winn was 0–3 and registered a 4.35 ERA with 51 strikeouts in 41.1 innings pitched (11.1 strikeouts per 9 innings), and a 50.9% ground ball rate. He has a mid-to-upper-90s fastball that has hit 100 mph, a "nasty" splitter, and a slider. Giants manager Gabe Kapler said: "His split has a chance to be really evil."
On June 12, 2023, Winn was promoted by the San Francisco Giants to the major leagues for the first time. Before his call-up and until one day prior to his major league debut, the 25-year-old Winn had never in his life been to a Major League Baseball stadium.
Winn made his MLB debut on June 13, against the St. Louis Cardinals, and in four innings gave up one run on one hit while walking three batters 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. Giants manager Gabe Kapler said: "He’s going to be good. He’s got a chance to be even better than he was tonight. He pitched well. He can pitch better."
