Come June, with the strains of "Take Me Out to the Ball Game," all over Washington D.C., grown men burst into tears.The Senators they loved have left and the senators they're left with are of no use at all when the baseball season opens.

The baseball fan, though perhaps gentler in his affections than the football fan, is no less determined. Bereft of a local team to love, he or she must put pride in pocket and turn to Baltimore and the Orioles.

Taking a party to Memorial Stadium for an afternoon or evening of baseball is one of the area's last good buys. The Baltimore Orioles charge $2.50 for general admission ($1.75 for children under 12 and senior citizens); $3.50 for upper and lower reserved seats; $5.25 for the mezzanine or terrace boxes and $6.50 for box seats.

There is even a bus to take you to the Sunday games.It leaves Beltway Plaza Shopping Center (off Beltway Exit 28 on Greenbelt Road) at 12:30 p.m. and costs $4, round trip. Reservations are made through Max Leiderman, 622-2550, who needs a check by the Thursday preceding the game in order to confirm them.

If you do drive, take 495 to Interstate 95 north into Baltimore city. Rte. 95 becomes Russell Street; continue until the street curves right, at which point turn right onto Pratt Street, east on Pratt to Calvert Street, where you turn left. Continue on Calvert to 33rd Street. Turn right and take 33rd until you see the stadium on your left.

You could pack a picnic - country pate spread on dark bread with Dijon mustard and thick slices of tomato, and, to drink, a hearty burgundy.

You could , but I suspect it's un-American. Baseball games mean steamed hot dogs all squishy with relish and foamy beer set at your feet, ready to be kicked over when the home team makes a home run. CAPTION: Picture, Oriole Mark Belanger; Chart, Schedule of Remaining Games
