The never-ending little wars to end violence today find Mario Marois, Quebec defenseman, suspended for six NHL games for swinging his stick during the Feb. 14 Nordiques-Rangers game and Maurice Lucas, Lonnie Shelton and Tree Rollins docked by the NBA. Brian O'Neill of the hockey league came down hard on Marois because, "Although no injury resulted . . . this is the second match penalty assessed to this player in the last two seasons." Lucas of New York was fined $1,000 and Shelton of Seattle $500 for a fight during Feb. 9 Knicks-SuperSonics (the amounts include automatic $250 for ejection); Rollins of Atlanta $850 for a flagrant foul Feb. 12 versus Phoenix . . .

Ref Joe Lalli, chased by West Chester State folks in the AU game-ending hassle, had other hot times in the cold gym there at Fort Myer. That used to be GW's home arena, when 5-foot-8 Lalli scored 17 points per Colonial game in 1965-66 and '66-67 . . .

Legitimate fights: Golden Gloves regional semis tonight, 7, at Hillcrest Heights and Saturday, 7, at Prince George's Community College's Novak Fieldhouse. Trainer Dave Jacobs sends Ray Carroll, an international veteran with a 143-5 record, out at 156 pounds, and former national junior champ Floyd Favors heads the 119-pounders . . . Jose Correa's Latin Connection club on Columbia Road NW sent two of its boxers to Atlantic City's Tropicana for pro debuts this week and welterweights Maurice Blocker and Simon Brown beat Pennsylvania foes and won reengagements next month . . . By golly, if they can fight in hotels in Nevada, why not here? So, premiering March 19, Sheraton Washington, the Budweiser Washington Championship Boxing Games. First of a series of pro cards, if Irish Mike Baker versus Roger Leonard and welterweights Lloyd (Honey Boy) Taylor (8-0) vs. Bubba Walters (5-0), among 32 rounds of scheduled action, light the fire . . .

But, careful. Another ring death: Benjamin Davis, 22, in Albuquerque, five days unconscious since being knocked out by a 16-year-old opponent in Golden Gloves . . .

Base(ball: Bill Buckner's new Cub contract: five years, $2.6 million; gives up no-trade provision in torn-up three-year pact . . . Dave Revering, asking $325,000 after a .233, 17-RBI 1981, loses arbitration, but Yankee offer, $250,000, ain't bad . . . Players Association's Marvin Miller one more time smelling a rat that "brings into question the integrity of the game on the management side," blasts Cleveland trade of Sid Monge to Philadelphia (for Bake McBride). Asks what of the rule (instituted in last summer's settlement) against trading free agents (Monge) before June 15? Miller says Phillies "could have signed Monge and not lost McBride or any other player. But instead . . . In complete violation of the basic agreement, they've devised a scheme in which there be direct compensation." Phillie boss Paul Owens argues that Monge's value to his club grew with reports Tug McGraw may be slow to recover from offseason elbow surgery . . . Say it ain't so, we said, and Mr. and Mrs. Yaz say maybe it ain't, yet: Boston's Carl Yastrzemski and the divorce suit by his wife of 22 years, Carolann. Yaz says instead they'll try an eight-month separation "feeling that we can work everything out . . . get back together again. (We) talked more about our problems in the last two days than in the last 10 years" . . .
