BALTIMORE, JULY 9 -- Major league baseball's 1987 All-Star Game will include 13 first-time participants, including Mark McGwire, Matt Nokes and Dan Plesac, whom many fans had never heard of a year ago.

Meanwhile, Eddie Murray, Jim Rice and Reggie Jackson were left off the squads that were announced this afternoon, which immediately set off arguments.

Because each team must be represented, some deserving players were left off. One of those was Minnesota first baseman Kent Hrbek, who didn't make the AL team despite being among the leaders in home runs (23) and RBI (55). Instead, American League President Bobby Brown and Manager John McNamara chose Cleveland's Pat Tabler.

"I don't mind saying it," Hrbek said. "They can stick it. If they ask me next year, I ain't going."

Likewise, other first basemen were left off, including Murray (18 homers, 51 RBI), Pete O'Brien of Texas (18 homers, 54 RBI) and Wally Joyner of California (19 homers, 68 RBI). Although Hrbek was angry, Murray, a seven-time all-star, was not.

"It's not like me to say anything about something like this," he said. "Someone from every team must make it, and I realize that. I'm not going to be angry about it."

Besides the 13 first-time all-stars, there are 15 second-year players, giving the 56-player squads a decidedly young appearance.

McGwire, with 31 home runs and 64 RBI entering today's game, joins Kansas City third baseman George Brett, who failed for the first time in 12 seasons to be elected by the fans.

National League pitchers and reserves include left-handed pitcher Sid Fernandez and first baseman Keith Hernandez, giving the World Series-champion New York Mets four players in the game scheduled for Oakland next week. Catcher Gary Carter and outfielder Darryl Strawberry were elected starters.

McGwire has hit his homers in Oakland's first 83 games. When Roger Maris hit 61 homers in 1961, he needed only 77 games to hit his first 31.

Other AL selections included second baseman Lou Whitaker and shortstop Alan Trammell of Detroit, Toronto shortstop Tony Fernandez, and outfielders Kirby Puckett of the Twins, Larry Parrish of Texas, Harold Baines of Chicago and Dwight Evans of Boston.

Whitaker, though, said he might not play because he has "done nothing to deserve" the honor. "I'll let everybody know if I'll play," he said. "I've done nothing to deserve playing in the All-Star Game."

The AL pitchers: Seattle's Mark Langston, Boston's Bruce Hurst, New York's Dave Righetti, Plesac, Kansas City's Bret Saberhagen, Detroit's Jack Morris, California's Mike Witt, Toronto's Tom Henke and Oakland's Jay Howell. Detroit's Nokes made the team as a backup catcher.

NL President Bart Giamatti and Mets Manager Dave Johnson selected eight pitchers: Fernandez, Philadelphia's Steve Bedrosian, Los Angeles' Orel Hershiser, Cincinnati's John Franco, Pittsburgh's Rick Reuschel, Houston's Mike Scott and Chicago's Lee Smith and Rick Sutcliffe. Cincinnati's Bo Diaz and Atlanta's Ozzie Virgil will back up starting catcher Carter.

The NL named a reserve infield of Philadelphia second baseman Juan Samuel, and third baseman Tim Wallach and shortstop Hubie Brooks of Montreal. Reserve outfielders are San Diego's Tony Gwynn, Atlanta's Dale Murphy, Montreal's Tim Raines, San Francisco's Jeffrey Leonard, St. Louis' Willie McGee and Los Angeles' Pedro Guerrero.

Among AL pitchers who didn't make the team are Roger Clemens of Boston -- he would have gotten a bonus -- and Rick Rhoden of New York. Rhoden, third in the AL in victories, claims he was left off because of accusations he scuffs balls. "I don't know what else it could be," he said.
