No. 1 in basketball, No. 5 in football, No. 15 in hockey -- and in baseball, No. 20 and gone.

That's the Washington professional sports success standing, by won-lost percentage, for the 1970s, as compiled by Inside Sports magazine to cover all cities fielding teams in at least three of the four main big-league sports. (Sorry, soccer; you call yourself the sport of the '80s, anyway.)

There's food for thought on the table of 23 cities that qualify -- 12 with franchises in all four sports, for at least part of the past decade; 11 represented in three from among NFL, NBA, NHL, and the majors. Pittsburgh -- you guessed it -- is tops with a combined winning percentage of .575 and six world titles. The top seven are round out, in order, by Boston (.571), Los Angeles, Oakland, Baltimore at .551 (aided by the pre-Cap Centre Bullets and not burdened by a .283 hockey club, as was Washington), Minneapolis-St. Paul (hey, that .506 baseball club could have been ours!) and your nation's capital .534 (uplifted by the Bullets, who improved from .555 in Baltimore in the early '70s to .612 as a Washington team).

The 1970 an '71 Senators posted a .414 percentage before Shorting out for Texas -- which still didn't qualify the hockeyless. NBA-hoopless (ABA) didn't count Dallas area for the three-sports-or-more list that runs on down to San Diego's Cellar-dwelling .420.

Sleepy Floyd and Mike Frazier of GU's Big East champs are set for an Aug. 16-Sept. 1 basketball tour of gold-medal Yugoslavia with an 11-member all-star team from the conference; Connecticut's Dom Perno to coach . . .
