Pete Rose of The Philadelphia Phillies, making his 14th All-Star appearance, heads a dozen players named to the National League squad yesterday to complete the team that will face the American League at Los Angeles Tuesday night.

Rose, who holds a record for playing at five different positions in All-Star games, is the veteran of the NL bench, which will include three first-time choices -- outfielders Jose Cruz of Houston and Dale Murphy of Atlanta and third baseman Ken Reitz of St. Louis.

Also named to the team were catchers Gary Carter of Montreal and John Stearns of the New York Mets, infielders Dave Conception of Cincinati, Phil Garner of Pittsburgh and Keith Hernandez of St. Louis, and outfielders Ken Griffey of Cincinnati, George Hendrick of St. Louis and Dave Winfield of San Diego.

Carter was the only player chosen from the Expos, leaders in the NL East Division. Cruz joins pitcher J. R. Richard as the lone representatives of the Astros, leading the NL West.

Fan balloting elected the eight starters, with Steve Garvey of Los Angeles at first base, Davey Lopes of Los Angeles at second, Bill Russell of Los Angeles at shortstop, Mike Schmidt of Philadelphia at third base, Pittsburgh's Dave Parker, Reggie Smith of Los Angeles and Dave Kingman of Chicago in the outfield and catcher Johnny Bench of Cincinnati. kParker was the MVP of last year's game at Seattle, won by the NL, 7-6.

Still to be named is a replacement for San Francisco pitcher Vida Blue, who was chosen for the team but is injured. Since Blue had been his team's only representative, his spot must go to a Giant. Every team must have at least one player on the All-Star squad.

The selection of reserves differed greatly from the fan balloting. Overlooked were catchers Steve Yeager of Los Angeles and Ted Simmons of St. Louis, who were second and third behind Bench in the balloting. Carter finished fourth in the voting and Stearns eighth.

Also left off the team were Pittsburgh's Willie Stargell, runner-up in the voting at first base, Ron Cey of Los Angeles, second in the balloting at third base, and outfielders Dusty Baker of Los Angeles, Greg Luzinski of Philadelphia and Ron leFlore of Montreal, runners-up in the outfield voting, Winfield was eighth, Hendrick 11th and Griffey 14th in the fan vote.

AL manager Earl Weaver yesterday added 15 players to the roster, including three Milwaukee Brewers and two each from the New York Yankees, Detroit Tigers and Texas Rangers.

First baseman Cecil Cooper, shortstop Robin Yount and outfielder Ben Oglivie -- the league's leading home run hitter with 21 -- were selected by Weaver from the Brewers. Third baseman Graig Nettles and second baseman Willie Randolph were selected from the Yankees.

Catcher Lance Parrish and shortstop Alan Trammell were picked from the Tigers, while Weaver chose third baseman Buddy Bell and outfielder Al Oliver from Texas.

Also selected by Weaver were Kansas City catcher Darrell Porter, California Angel second baseman Bobby Grich, Baltimore outfielder AL Bumbry, outfielder Ken Landreaux of Minnesota, Cleveland outfielder Jorge Orta and outfielder Rickey Henderson of Oakland.

Three of the eight elected starters -- Kansas City third baseman George Brett, Milwaukee second baseman Paul Molitor and Boston outfielder Jim Rice -- are out because of injuries but are expected to sit on the bench with the squad.
