BALTIMORE -- The Orioles announced their Spring Training roster on Tuesday morning, with 15 non-roster invitees expected in big league camp. Two of the most notable names are prospects Dariel Alvarez and Hunter Harvey, who was the club's first-round pick in the 2013 First-Year Player Draft.

Alvarez is considered one of the organization's best defensive prospects, and he could push to join the Major League club very soon. Harvey is coming off a season-ending flexor mass strain sustained in July, but he has had a normal offseason and should be a full-go in camp.

Other signings include outfielder Nolan Reimold, which the club announced earlier this week, and the return of veteran pitcher Mark Hendrickson. Steve Johnson, who re-signed as a free agent this winter, will also be in big league camp. Michael Almanzar, who was the O's Rule 5 Draft pick last season, also made the cut.

Baltimore's pitchers and catchers will report on Feb. 19, with the first workout scheduled for the following day. The first full-squad workout will be on Feb. 25.

Here is the full list:

Pitchers: RHP Dane De La Rosa, RHP Harvey, LHP Hendrickson, RHP Johnson, LHP Chris Jones, RHP Chaz Roe.

Catchers: J.P. Arencibia, Ryan Lavarnway, Brian Ward.

Infielders: Almanzar, Paul Janish, Chris Parmelee.

Outfielders: Alvarez, Reimold, Matt Tuiasosopo.
