The flavor of Baltimore's Florida Grapefruit League news ripened considerably late today when the Orioles were advised that Ron Hansen has fulfilled his obligations under the Army's military training program and is ready for belated spring training.

Hansen, who slugged the 1960 Oriole high of 22 homers and drove in 86 runs on a.255 freshman average, completes the Birds' spring squad at 49 players.

The big, 22 -- year old shortstop, the 1960 American league ``rookie of the year,'' flew here late this afternoon from Baltimore, signed his contract for an estimated $15000 and was a spectator at tonight's 5 -- to 3 loss to Kansas City -- the winless Birds' sixth setback in a row.

The 6 -- foot 3 inch Hansen checked in close to 200 pounds, 15 pounds lighter than his reporting weight last spring. He hopes to melt off an additional eight pounds before the Flock breaks camp three weeks hence.

When he was inducted into the Army at Fort Knox, Ky., Hansen's weight had dropped to 180 -- ``too light for me to be at my best'' he said.

``I feel good physically,'' Hansen added, ``but I think I'll move better carrying a little less weight than I'm carrying now.''

The rangy, Albany (Cal.) native, a surprise slugging sensation for the Flock last year as well as a defensive whiz, set ``improved fielding'' as his 1961 goal.

``I think I can do a better job with the glove, now that I know the hitters around the league a little better,'' he said.
