Fifty-five players appeared in a game for the Nationals last season, and six of them made their major league debuts in the process.

At least one of those debuts, by Cade Cavalli, was both expected and promoted. The others, though, came as something of a surprise, whether it was Lucius Fox making the Opening Day roster, Jackson Tetreault and Evan Lee getting summoned to start big league games after others got hurt, Israel Pineda getting a September call-up or Joey Meneses finally making it at age 30.

A 162-game season is full of twists and turns, and the 2022 season had no shortage of those from the Nationals’ perspective. And there’s every reason to believe the 2023 season will feature a number of debuts, of both the expected and the unexpected variety.

Who might we see don a curly W cap for the first time?

The likeliest candidate among the organization’s top prospects is Robert Hassell III, though the 21-year-old outfielder is hardly a lock to make it to D.C. this season.

The signing of Trevor Williams – which became official Saturday night – wasn’t anything that was going to send shock waves through Nationals Park or the baseball world. A two-year, $13 million deal for a 30-year-old right-hander with a career 4.27 ERA is hardly the kind of move that shapes a team’s fortunes to any great extent.

What the Williams signing did do, however, was punctuate a point the Nationals seem to be making this winter: If they can’t spend big on top-tier pitchers, they’re going to make sure they get guys who can comfortably bounce back and forth from the rotation to the bullpen.

That was Williams’ role in New York this season. When the Mets were dealing with rotation injuries from April through June, he was asked to start every five days. When that rotation finally was healthy from July through September, he shifted into a long relief role.

In that respect, Williams proved to be hugely valuable to a Mets roster that was loaded with star power but needed his versatility and effective performance to navigate through a long season that ended with a berth in the National League Wild Card Series.

Williams did whatever New York needed of him. He made nine starts. He made 21 relief appearances. He finished five games. He recorded one save. He completed at least two innings in 13 of his relief outings, completing at least four innings in four of those.

SAN DIEGO – With their first Rule 5 draft pick in a dozen years, the Nationals took a flyer on a right-hander who recently returned from Tommy John surgery, hoping he can make it through the entire 2023 season on the major league roster, most likely as a multi-inning reliever before ultimately joining the rotation.

Thad Ward, who spent the last five seasons in the Red Sox organization, was the Nats’ pick of the litter, going No. 1 in today’s Rule 5 draft, which unofficially wraps up the Winter Meetings.

"It makes you feel good as a player to know that other teams value you," Ward said in a conference call with reporters. "It’s really rewarding to see your hard work get seen. … Honestly, I’m just thankful. I’m going to leave it at that. I’m thankful for the opportunity, and I’m ready to get to work with the Nats and get this thing going.”

Ward, who turns 26 next month, was Boston’s organizational pitcher of the year in 2019 after posting a 2.14 ERA and 157 strikeouts in 25 combined starts between both levels of Single-A. He hasn’t pitched much since then, though, missing the 2020 season (along with all other minor leaguers) because of the pandemic, then missing most of the 2021 and 2022 campaigns while recovering from Tommy John surgery.

Ward returned strong this summer, producing a 2.28 ERA and 66 strikeouts across 51 1/3 innings at three levels of the Red Sox system. Seven of his starts came at Double-A Portland, where he had a 2.43 ERA and 11.1 strikeouts per nine innings.
