The Orioles once again performed at the plate in powderpuff fashion, gathering only seven blows off the offerings of three Kansas City pitchers. Three were doubles, Brooks Robinson getting a pair and Marv Breeding one.

Bill Kunkel, Bob Hartman and Ed Keegan did the mound chores for the club down from West Palm Beach to play the game before 767 paying customers in Miami Stadium.

The Birds got five hits and all three of their runs off Kunkel before Hartman took over in the top of the fourth. Hartman, purchased by the A's from the Milwaukee Braves last fall, allowed no hits in his scoreless three inning appearance, and merited the triumph.

Keegan, a 6 -- foot -- 3 -- inch 158 -- pounder, gave up the Orioles' last two safeties over the final three frames, escaping a load of trouble in the ninth when the Birds threatened but failed to tally.

In the ninth, Robinson led off with his second double of the night, a blast off the fence 375 feet deep into left.

Whitey Herzog, performing in right as the Orioles fielded possibly their strongest team of the spring, worked Keegan for a base on balls.

Then three consecutive pinch hitters failed to produce.

Pete Ward was sent in for House and, after failing in a bunt attempt, popped to Howser on the grass back of short.

John Powell, batting for Adair, fanned after fouling off two 2 -- and 2 pitches, and Buddy Barker, up for Stepanovich, bounced out sharply to Jerry Lumpe at second to end the 2 -- hour and -- 27 -- minute contest.
