Slade Cecconi Bio
Slade Gustave Cecconi is an American professional baseball pitcher for the Cleveland Guardians of Major League Baseball (MLB). The right-hander made his MLB debut in 2023 with the Arizona Diamondbacks before being traded to the Cleveland Guardians ahead of the 2025 season. Known for his workhorse frame and strikeout ability, Cecconi has emerged as a young starter working to establish himself as a long-term member of a major-league rotation.
Cecconi was selected by the Arizona Diamondbacks with the 33rd overall pick in the 2020 MLB draft out of the University of Miami. He rose through the Diamondbacks’ minor-league system, reaching the majors in 2023, and was later traded to Cleveland in a deal that sent Josh Naylor to Arizona. He currently wears number 44 for the Guardians.
Early Life and Background
Slade Gustave Cecconi was born on June 24, 1999, and grew up in the Orlando, Florida, area. He attended Trinity Preparatory School in Winter Park, Florida, where he starred on the baseball team. As a junior in 2017, he went 6–1 with a 0.70 earned run average and recorded 70 strikeouts over 40 innings, quickly establishing himself as one of the top amateur arms in the country.
That summer, Cecconi was selected to play in the Under Armour All-America Baseball Game at Wrigley Field in Chicago, a showcase event for elite high-school talent. In his senior year of 2018, he also proved capable at the plate, batting .388 with six home runs, before being selected by the Baltimore Orioles in the 38th round of the 2018 MLB draft. Cecconi did not sign with Baltimore, choosing instead to honor his commitment to the University of Miami.
Path to Professional Baseball
Cecconi enrolled at the University of Miami, where he played college baseball for the Miami Hurricanes. As a freshman in 2019, he appeared in 17 games with 13 starts, going 5–4 with a 4.16 ERA and 89 strikeouts across 80 innings. He was also selected to play in the Cape Cod Baseball League for the Wareham Gatemen but did not participate in the showcase summer league.
In his sophomore season of 2020, Cecconi made four starts and posted a 2–1 record with a 3.80 ERA over 21⅓ innings before the season was cut short by the COVID-19 pandemic. Despite the abbreviated year, his strong freshman campaign and overall ceiling convinced the Arizona Diamondbacks to make him the 33rd overall selection in the shortened 2020 MLB draft, and he signed with the club on July 10, 2020, for a $2.4 million bonus.
Slade Cecconi Career
Early Career (2021–2022)
Cecconi was assigned to the Hillsboro Hops of the High-A West to begin the 2021 season, though a wrist injury delayed his debut to mid-May. He later suffered an elbow injury that ended his year in early August, finishing 2021 with a 4–2 record, a 4.12 ERA, and 63 strikeouts in 59 innings across 12 starts. Following the season, he was selected to play in the Arizona Fall League for the Salt River Rafters.
In 2022, Cecconi advanced to the Amarillo Sod Poodles of the Double-A Texas League, where he made 25 starts and posted a 7–6 record with a 4.37 ERA and 127 strikeouts over 129⅔ innings. The strong workload and strikeout totals positioned him as a legitimate starting-pitching prospect within the Arizona system heading into 2023.
Arizona Diamondbacks (2023–2024)
Cecconi opened 2023 with the Reno Aces of the Triple-A Pacific Coast League, going 4–8 with a 6.38 ERA and 104 strikeouts in 103 innings across 20 starts. On August 2, 2023, the Diamondbacks selected him to the 40-man roster and promoted him to the major leagues for the first time. In his rookie campaign, he appeared in seven games with four starts, posting a 4.33 ERA and 20 strikeouts over 27 innings.
He was optioned to Reno to begin 2024, where he posted a 3.06 ERA over 47 innings. Cecconi also made 20 appearances with 13 starts for the Diamondbacks that year, going 2–7 with a 6.66 ERA and 64 strikeouts across 77 innings. His inconsistent results led Arizona to explore trade options during the off-season.
Cleveland Guardians Era (2025–Present)
On December 21, 2024, the Arizona Diamondbacks traded Cecconi and a competitive balance draft pick in the 2025 MLB draft to the Cleveland Guardians in exchange for first baseman Josh Naylor. The deal gave Cleveland a young, controllable arm for its rotation and gave Cecconi a fresh start in the American League.
In 2025, Cecconi was a member of Cleveland’s starting rotation for the majority of the season, making 23 starts and going 7–7 with a 4.30 ERA and 109 strikeouts across 132 innings. He is currently listed on the Cleveland Guardians’ major-league roster and continues to develop as a middle-of-the-rotation arm.
Driving Style and Strengths
Cecconi is a power-armed right-hander whose strengths are generating swings and misses with his fastball and breaking pitches, evidenced by his consistent strikeout totals throughout the minor leagues and majors. His 6-foot-3 frame and durable build allow him to work deep into starts, as shown by his 132-inning workload in 2025. He is regarded as a strikeout-oriented starter working to refine his command and limit hard contact.
Notable Events and Milestones
Cecconi’s first major milestone came on August 2, 2023, when he was promoted to the majors for the first time by the Arizona Diamondbacks. His next major moment arrived on December 21, 2024, when he was traded to the Cleveland Guardians in the Josh Naylor deal, giving him an opportunity to anchor a new rotation. He also earned an invitation to the Under Armour All-America Baseball Game at Wrigley Field in 2017 and was selected to the Arizona Fall League in 2021, both early indicators of his professional ceiling.
