Ferrer was a workhorse for the Nationals in 2025, logging a career-high 76.1 innings that ranked ninth overall among relief pitchers. The southpaw led Washington in holds (21) and WPA (0.78) while maintaining the lowest walk rate (4.9 percent). He tossed more sinkers (71 percent pitch usage) than ever to produce a 62.6 ground ball percentage that ranked third among qualified relievers. Ferrer didn't strike many batters out - his 21.9 percent K-rate was slightly below league average - but he did produce one of the highest whiff rates in the league (47 percent) among those who tossed a minimum of 200 changeups. After Washington traded closer Kyle Finnegan, Ferrer took on the majority of the Nats' save opportunities, racking up 11 of the team's 16 saves over the final two months (68.5 percent share). Ferrer appeared set to be a part of the late-inning mix for Washington again in 2026, but he was instead traded to Seattle in December. The 25-year-old is now likely to begin the season in middle relief since Andres Munoz is locked in at closer with Matt Brash and Gabe Speier in setup roles. Read Past Outlooks
