Alan Wiggins, a former Baltimore Oriole and the second baseman on the San Diego Padres' 1984 pennant-winning team who had a long history of drug abuse, died Sunday night. He was 32.

Ron Wise, a spokesman for Cedars-Sinai Medical Center in Los Angeles, said Wiggins died of pneumonia, tuberculosis and other medical complications at 9:45 p.m. Sunday.

Wiggins played seven years in the majors with the Padres and the Orioles. As a member of the Padres in 1982, he was suspended for 30 days after being arrested for cocaine possession.

In 1983 he played the outfield and first base for the Padres and was named the team's most valuable player, batting .276 and stealing 66 bases. He switched to second base in 1984 and stole 70 bases. Wiggins batted .341 in the postseason, including a .364 mark in the 1984 World Series, which San Diego lost to Detroit in five games. . . .

A federal judge in New York denied Commissioner Fay Vincent's motion to dismiss a lawsuit by New York Yankees executive vice president Leonard L. Kleinman.

U.S. District Judge Leonard B. Sand, in a two-page memorandum, decided to allow Kleinman's lawyers discovery in the case. Kleinman was blocked by Vincent from succeeding George Steinbrenner as the team's managing general partner because the commissioner was investigating Kleinman at the time.

Kleinman was cleared of any wrongdoing in a $40,000 payment to Howard Spira, and is now seeking damages from Vincent.

The commissioner's office claims the suit is an attempt to gain a public forum to raise Steinbrenner's grievances against the commissioner.

The Yankees, meanwhile, have selected Mike Hart manager of the Class A Carolina League Prince William Cannons. Dave Schuler and Rob Thompson, who last season coached under Hart in Fort Lauderdale, also will join the Cannons' staff. . . .

Los Angeles Dodgers shortstop Alfredo Griffin had minor back surgery yesterday and is expected to be at full strength by spring training. Griffin, 33, batted .210 in 141 games for the Dodgers in 1990.
