NEW YORK (AP) _ St. Louis first baseman Mark McGwire, who has reached the halfway point in his pursuit of Roger Maris' home run record, leads all National League players in balloting for the 69th All-Star Game.

In the voting through June 15 that was released Monday by the commissioner's office, McGwire had 1,580,344 votes, 231,068 more than New York Mets catcher Mike Piazza, the NL's top vote-getter in 1996 and 1997.

McGwire, who is on a pace to shatter both the home run and RBI records, is competing for his first elected start in the NL and sixth appearance overall. He was elected to start at first base for the American League in 1987 and 1991, and selected as a reserve in 1992, '95 and '97, all with Oakland.

Other NL position vote leaders were: second baseman Craig Biggio of Houston (1,190,254); outfielders Tony Gwynn of San Diego (1,181,776), Barry Bonds of San Francisco (939,692) and Larry Walker of Colorado (824,344); and third baseman Chipper Jones (793,918) and shortstop Walt Weiss (551,138) of the Atlanta Braves.

The game will be played July 7 at Coors Field in Denver.
