Konnor Chase Pilkington (born September 12, 1997) is an American professional baseball pitcher for the Washington Nationals of Major League Baseball (MLB). The left-hander has built his career through the minor league systems of three organizations before reaching the big leagues. He previously appeared in MLB for the Cleveland Guardians.
Early Life and Background
Konnor Chase Pilkington was born on September 12, 1997, in Hurley, Mississippi, a small community in the southeastern part of the state. He grew up in a region where high school baseball has long served as a primary path toward college and professional opportunities. From an early age, Pilkington showed the traits of a future starting pitcher, working on his mechanics and developing the kind of polish that scouts look for in young arms.
Pilkington attended East Central High School in Hurley, Mississippi, where he became one of the most productive pitchers in the program’s history. Across his high school career, he compiled a 25–7 win–loss record, posted a 1.70 earned run average, totaled 307 strikeouts, and held opposing hitters to a .144 batting average. In June 2014, at just 16 years old, he committed to Mississippi State University to play college baseball, signaling his status as one of the top amateur prospects in Mississippi.
Path to Professional Baseball
As a freshman at Mississippi State in 2016, Pilkington went 3–1 with a 2.08 ERA and 42 strikeouts in 14 appearances, including 11 starts. He followed that summer by pitching in the Cape Cod Baseball League for the Brewster Whitecaps, where he went 2–1 over more than 39 innings, finished third in the league with a 1.37 ERA, and earned a spot on the CCBL 2016 Year-End All-League Team. The performance established him as one of the top college pitchers heading into his sophomore year.
In 2017, Pilkington started a team-high 17 games for the Bulldogs, going 8–5 with a 3.08 ERA and 111 strikeouts in 108 innings. That summer, he was invited to play for the USA Baseball Collegiate National Team, pitching against Cuba, Japan, and Chinese Taipei while collecting a 2.65 ERA in five appearances. As a junior in 2018, he was named a Preseason All-American by Baseball America, Collegiate Baseball, the NCBWA, and Perfect Game, and served as Mississippi State’s Friday night starter before being selected in the 2018 MLB Draft.
Konnor Pilkington Career
Early Career (2018–2020)
The Chicago White Sox selected Pilkington in the third round of the 2018 Major League Baseball Draft, and he signed with the organization for a $650,000 signing bonus. He made his professional debut with the Rookie-level Arizona League White Sox before being promoted to the Great Falls Voyagers of the Rookie Advanced Pioneer League. Over 14 innings between the two clubs, he posted a 7.07 ERA. In 2019, Pilkington opened the year with the Kannapolis Intimidators of the Class A South Atlantic League, going 1–0 with a 1.62 ERA in six starts before a midseason promotion to the Winston-Salem Dash, where he finished the year with a 4–9 record and a 4.99 ERA in 19 starts, striking out 96 batters in just over 95 innings.
The 2020 minor league season was canceled due to the COVID-19 pandemic, and Pilkington returned to action in 2021 with the Double-A South’s Birmingham Barons. Over 14 starts for the Barons, he went 4–4 with a 3.48 ERA, a 0.92 WHIP, and 71 strikeouts across 62 innings, putting together the most consistent stretch of his early professional career.
Cleveland Indians / Guardians Era (2021–2023)
On July 29, 2021, the White Sox traded Pilkington to the Cleveland Indians in exchange for César Hernández, and he was assigned to the Akron RubberDucks of the Double-A Northeast. In eight games and seven starts with Akron, he went 3–2 with a 2.33 ERA and 49 strikeouts in just over 38 innings. On November 19, 2021, the newly rebranded Cleveland Guardians added him to their 40-man roster to protect him from the Rule 5 Draft.
Pilkington was named to Cleveland’s Opening Day roster in 2022, and on April 15, he made his MLB debut after a brief phantom ballplayer stint. He went on to pitch in 15 games with 11 starts for the Guardians in 2022, going 1–2 with a 3.88 ERA and 50 strikeouts in 58 innings. He began 2023 at Triple-A Columbus, where he struggled, and made only one appearance for Cleveland before being designated for assignment on April 26, 2023, following the promotion of pitcher Tanner Bibee.
Arizona Diamondbacks Era (2023–2024)
On May 1, 2023, the Cleveland Guardians traded Pilkington to the Arizona Diamondbacks in exchange for cash considerations. He was assigned to the Triple-A Reno Aces, where he struggled to a 9.53 ERA in 11 starts while striking out 37 batters in just under 40 innings. On July 7, 2023, he was designated for assignment following the promotion of Dominic Canzone, cleared waivers, and was outrighted to Triple-A Reno on July 13.
Pilkington spent the entirety of the 2024 campaign with the Reno Aces. In 33 appearances and 21 starts, he compiled a 3–5 record and a 5.91 ERA with 79 strikeouts across just over 77 innings. Following the season, he elected free agency on November 4, 2024.
Washington Nationals Era (2024–Present)
On December 3, 2024, Pilkington signed a minor league contract with the Washington Nationals and was assigned to the Triple-A Rochester Red Wings. In 36 appearances out of the Rochester bullpen, he posted a 4–3 record and a 2.59 ERA with 50 strikeouts and two saves across just over 41 innings. On July 22, 2025, the Nationals selected his contract and added him to their active roster, returning him to the major leagues for the first time since 2023.
Driving Style and Strengths
Pilkington is a left-handed pitcher who relies on command and pitchability rather than overpowering velocity. His best stretch in the minors came when he consistently threw strikes and kept his WHIP low, as he did in 2021 with Birmingham (0.92) and again in 2025 with Rochester (2.59 ERA). His ability to work as both a starter and a reliever has given him the flexibility that organizations look for in a multi-inning arm.
Notable Events and Milestones
Pilkington’s most notable milestones include his MLB debut on April 15, 2022, with the Cleveland Guardians, his 2016 Cape Cod Baseball League All-League selection, and his selection to the 2017 USA Baseball Collegiate National Team. His return to the major leagues with the Washington Nationals in July 2025 marked his first big league appearance since 2023.

At the lower levels, his 2016 summer with the Brewster Whitecaps stands out, as he posted a 1.37 ERA over more than 39 innings. His 2025 performance with the Rochester Red Wings, where he posted a 2.59 ERA in 36 appearances, served as the springboard for his return to the major leagues.

2025 Season Performance
Konnor Pilkington began the 2025 season with the Triple-A Rochester Red Wings after signing a minor league deal with the Washington Nationals in December 2024. Working primarily out of the bullpen, he delivered one of the most consistent stretches of his professional career, going 4–3 with a 2.59 ERA, 50 strikeouts, and two saves in 36 appearances across just over 41 innings. The performance earned him a return to the major leagues.
On July 22, 2025, the Washington Nationals selected Pilkington’s contract and added him to the active roster, putting him back in a major league clubhouse for the first time since the 2023 season. His role with the Nationals is expected to be that of a multi-inning relief arm who can spot start when needed, giving the Washington pitching staff a second left-handed option out of the bullpen.
Looking ahead, Pilkington’s main objective is to solidify his place on the Nationals’ roster through the remainder of the 2025 season. With a track record of strong minor league performance in 2025 and prior big league experience with Cleveland, he will look to translate his Triple-A success into consistent major league results as he works to extend his time in the Washington bullpen.
