Former Red Sox pitching prospect Noah Dean has agreed to terms on a minor league contract with the Washington Nationals, according to The Nats Report.
Dean was released by the Red Sox on March 19 after spending parts of four seasons in the organization. The 25-year-old left-hander was originally selected in the fifth round (159th overall) of the 2022 draft out of Old Dominion. At that time, Paul Toboni — now the Nationals’ president of baseball operations — served as Boston’s director of amateur scouting, so there is a level of familiarity there.
A New Jersey native, Dean received a $322,500 signing bonus from the Red Sox in July 2022 but did not make his professional debut until the following April. The lefty spent all of 2023 and the first half of 2024 at Low-A Salem before being promoted to High-A Greenville that July. He then returned to Boston’s South Atlantic League affiliate for the start of the 2025 campaign.
In 22 appearances (15 starts) for Greenville last year, Dean posted a 5.68 ERA with 81 strikeouts to 48 walks over 63 1/3 innings in which he held opponents to a .219 batting average. He reached Double-A Portland for the first time in September and was solid in his lone outing for the Sea Dogs, scattering one hit and one walk while striking out one across 2 2/3 scoreless frames of relief.
Altogether, Dean owns a lifetime 5.35 ERA with 284 strikeouts to 175 walks across 66 career minor league appearances (47 starts) spanning 208 2/3 innings between Low-A, High-A, and Double-A. He has struck out nearly 30% of the batters he faced while limiting opponents to a .198 clip, but his 18.4% walk rate highlights ongoing issues with command and control.
Standing at 6-foot-2 and 185 pounds, Dean features a 93-95 mph fastball that reaches 97 mph. The athletic southpaw has also incorporated an 80-83 mph curveball, an 88-92 mph cutter, an 82-83 mph sweep, and a 77-79 mph curveball into his arsenal in the past, as noted in his SoxProspects.com scouting report.
Dean, who just turned 25 on March 10, will presumably report to either Washington’s High-A affiliate in Wilmington or Double-A affiliate in Harrisburg in the coming days. He is the latest notable pitching prospect to go from the Red Sox to the Nationals in recent months, albeit through different means.
In December, Boston traded hard-throwing righty Luis Perales to Washington for 6-foot-6 lefty Jake Bennett, and both made their organizational debuts with their new clubs’ Triple-A affiliates over the weekend.
