Washington Nationals Free Agent Profile: RHP Michael King

After announcing a flurry of roster moves to reset the 40-man roster to kick off free agency, the Washington Nationals have a laundry list of roster needs this offseason that start with its pitching staff. With the Cade Cavalli extension and Connelly Early acquisition giving manager Blake Butera two dependable pieces to lean on in the rotation, the question now turns to who president of baseball operations Paul Toboni can turn to as part of the solution in 2027. Yet maybe one of the most desirable options became officially available to begin the offseason.

Right handed starting pitcher Michael King elected to decline his player option with the San Diego Padres, officially entering free agency and becoming one of the top available arms this offseason.

The 31 year old is coming off a 2026 season where he recorded 159 strikeouts, the third time in his last four seasons that he eclipsed 100 strikeouts in a regular season. He also recorded a 3.21 ERA and 1.18 WHIP, the latter marking his best since his fifth and final season with the New York Yankees.

His strikeout-to-walk ratio has steadily declined since 2022, now coming off a 2026 season where he recorded a career-worst 2.3, but his 2026 season also featured several impressive moments. King recorded two starts during the Padres' postseason run where he allowed just one run and tossed 14 strikeouts across 12 innings, while he also recorded a career-best 4.3 wins above replacement in the regular season. He did so while eclipsing 30 starts in 2026, marking the fourth time over his last five seasons he's done so, to ease concerns about durability.

King also ranked in the 93rd percentile in overall pitching value in 2026 after posting a 12-10 overall record, the second time in his career he has eclipsed double digit wins.

While a reunion with San Diego could ultimately materialize, King would be the type of signing that could serve as a signature piece in the rotation for Washington -- and prove serious about the commitment to upgrading a sore spot. After limping through the first half of year one with inning eaters like Miles Mikolas and Zack Littell, King serves as arguably the crown jewel for the Nationals in the starting pitching market. Amid a perceived weaker free agent market, King also serves as the chance for the Nationals to prove themselves as an early offseason winner.
