We now have a Spring Training schedule. Note that this looks different from previous years — other than a final game in Lakeland, the Rays won’t be coming north of Manatee County. Current plans at Port Charlotte calls for limited attendance; check with the other host teams to find out whether you can attend games at other venues.
And here is the Rays official Spring Training roster. They have 73 players (75 is the maximum).
Pitchers, pitchers everywhere! The Rays have a bunch of new signings, some on minor league deals but most notably major league deals with Collin McHugh and Rich Hill.
