The New York Yankees acquired left-hander Al Leiter from the Florida Marlins and scheduled him to start Sunday's series finale against the Boston Red Sox. Details of the trade were expected to be announced after Saturday's game. ``He's a competitor -- like that Game 5 start in the (2000) World Series,'' manager Joe Torre said before the deal was final. ``The most intriguing part is the experience and New York. You hope to catch lightning in a bottle.'' The Yankees are desperate for pitching help with four starters on the disabled list. Torre said Kevin Brown, who has been on the DL since June 16 with a back strain, will return to start on Monday. The Marlins designated Leiter for assignment on Thursday after he went 3-7 with a 6.64 ERA this season. He is due to make $8 million this year despite struggling to pitch like he did in his first stint with the team, when he won 27 games and helped the Marlins with the 1997 World Series. Leiter, 39, started his career with the Yankees but was traded to Toronto in 1989. He signed with the Marlins as a free agent before the '96 season and threw Florida's first no-hitter that year, but he was traded to the Mets during the Marlins' post-World Series payroll purge. Leiter won a career-best 17 games for the Mets in 1998 and pitched a two-hit shutout.
