We're talking fines again:

* Del Harris, Houston Rockets' coach, $1,000 by the NBA for overly ragging at the officiating during, and for public consumption after, 119-117 loss to Spurs. Does that forebode anything for Abe Pollin, issuer of emphatic noncompliments about Celtics-Bullets refereeing in his Capital Centre? Tsk, and Commissioner Larry O'Brien due here Monday to present Pollin as one of eight inductees at Washington Metropolitan Basketball Hall of Fame inaugural dinner (Marriott Twin Bridges).

* Lou Piniella, N.Y. Yankee outfielder, $1,000 by Manager Bob Lemon for nonfeasance on top of $7,000 by owner George Steinbrenner for overweight. Piniella left park before p.m. exhibition with Texas at Pompano Beach. Seems, during a.m. Yanks-Rangers B game, he was telling a story, with gestures, when--oops--his hand hit the dugout roof. Hand swelled but he finished game before going for X-rays (no fracture). Lemon: "He left without telling us. He knew we wanted him to DH in the second game."

Boss Steinbrenner describes Piniella as "like a child who tests you with how many times he can go to the cookie jar . . . Once in awhile he has to be belted good . . . 38 years old and I gave him a three-year contract at $350,000 a year . . . more than anybody else in baseball would have given him." Piniella retorts, "They're treating me like Little Orphan Annie . . . I also must be the biggest dummy in the world because I came into camp early (pre-March, as Steinbrenner "requested" of regulars), so what happens? I have to weigh in every day and I keep getting fined $1,000."
