In the current year, Pfaadt will earn $799,400 before his new contract takes effect next season.

Pfaadt was drafted in the fifth round of the 2020 MLB Draft from Bellarmine University.

The Arizona Diamondbacks have signed left-handed pitcher Brandon Pfaadt to a five-year, $45 million contract, announced on March 28, 2025.

This contract will commence in the 2026 season and includes a club option for 2031 as well as a mutual option for 2032.

At just 26 years old, Pfaadt had a standout previous season, achieving an 11-10 record with a 4.71 ERA, along with career highs of 32 starts, 181.2 innings pitched, and 185 strikeouts.

This signing reflects the Diamondbacks' strategy to secure young talent on long-term contracts, following similar extensions for shortstop Geraldo Perdomo and reliever Justin Martinez.

He played a crucial role in the Diamondbacks' postseason success in 2023, posting a 3-1 record with a 3.27 ERA across five starts during their World Series run.
