The Nationals formally announced their list of 18 spring training non-roster invitees, essentially the players without major league contracts and not on the 40-man roster who will be in major league camp in Viera. Many of the names are already known, such as veteran starter Chris Young, former original 2005 National infielder Jamey Carroll and catcher Chris Snyder, because those invitations were announced along with their minor league deals.

But also notably included are top Nationals prospects who could factor heavily in the organization’s future and who will be getting their first taste of big league camp:  Brian Goodwin, A.J. Cole and Blake Treinen. Goodwin, 23, rated as the Nationals top position player prospect, spent all of last season at Class AA Harrisburg and posted a .762 OPS. Cole, 22, the top Nationals pitching prospect after Lucas Giolito, is a hard-throwing right-handed starter who posted a 2.18 ERA over seven starts at Harrisburg, where he finished last season. And, Treinen, 25, another hard-throwing right-hander, spent most of last season at Harrisburg and punched up a 3.64 ERA over 118 2/3 innings.

Other invited prospects include outfielder Steven Souza Jr., right-handed starter Nate Karns, infielder Zach Walters, right-handed reliever Aaron Barrett, outfielders Michael Taylor, Jeff Kobernus and Eury Perez and left-handed starters Sammy Solis and Matt Purke.

Karns, Purke, Walters and Perez have had extended stints in big league camp in the past; Kobernus was in Detroit Tigers’ big league camp last spring before being returned to the Nationals as a Rule 5 pick. Matt Skole, who impressed at last year’s spring training but then missed most of the minor league season with injury, is invited as well.

Manager Matt Williams has said he wants a larger group of players in big league spring training than the past under Davey Johnson. Williams wants roughly 30 pitchers and 30 position players in camp, and it will be important for him to see many of the top prospects and minor league depth up close for the first time. The list of players going to big league camp stands at 58 so far, so there’s room for a few more minor league additions.
