The retailing arm of Major League Baseball yesterday sued a company that claims it owns trademark rights to the name Washington Nationals.

The lawsuit in U.S. District Court in Manhattan said Bygone Sports LLC tried to "turn a quick, undeserved profit" by seeking trademark registration rights to the club's name, even though it has been used for decades to refer to Washington teams.

Major League Baseball Properties Inc. and Baseball Expos L.P. asked the court to declare that the trademark does not belong to the company because its sole purpose in filing for a trademark was to capitalize on the naming of the new baseball team.

Michael Bergman, the chief executive officer and co-owner of the Atlanta-based Bygone, had no comment.

* LIKE FATHER, LIKE SON: Prince Fielder was called up by the Milwaukee Brewers, and the son of former major league star Cecil Fielder made his big league debut against the Tampa Bay Devil Rays. He went 0 for 4.

Prince Fielder, 21, whose contract was purchased from Class AAA Nashville, was Milwaukee's first-round pick in the 2002 amateur draft. He hit .253 with 15 homers and 47 RBI in 64 games with Nashville this season.

To make room for Fielder, Milwaukee sent C Julio Mosquera outright to Nashville.

* CALLING IT A DAY?: Larry Walker might retire after this season, citing age and injuries.

The 38-year-old Canadian entered the St. Louis Cardinals' game at Toronto last night hitting .249 with five homers and 23 RBI.

"A lot of people say you know when your time is up. I had an inclination last year that my time was up. I just decided to play this year and see what happens," Walker said. "It's a grind. The age and the surgeries that I've had are what's pushing me back, eight surgeries and a reconstructed knee. Father Time is creeping on me, and I realize that."
