Catcher Charles Johnson reversed his decision and approved a trade to the Colorado Rockies, his agent said yesterday, clearing the way for a six-player deal that sends left-hander Mike Hampton to the Florida Marlins.

Hampton might not stay in Florida for long. A lawyer familiar with the situation told the Associated Press on condition of anonymity that the Marlins were working on a deal that would send Hampton to the Atlanta Braves.

Braves General Manager John Schuerholz and Hampton's agent, Mark Rodgers, declined to comment. Marlins General Manager Larry Beinfest did not immediately return a phone call.

If the Braves acquired Hampton, it would probably end their interest in re-signing free agent lefty Tom Glavine, who has spent his entire 16-year career in Atlanta.

Johnson, who had used his no-trade rights to block the deal earlier yesterday, changed his mind after getting an additional $1 million to make up for the fact that there is no state income tax in Florida.

Taylor Fined for Gesture

Jacksonville Jaguars running back Fred Taylor was fined $10,000 by the NFL for making a "slashing of the throat gesture" against the Washington Redskins last Sunday, his second such punishment this season.

Taylor was docked $5,000 for making the same motion after scoring a touchdown against the Chiefs on Sept. 15, league spokesman Steve Alic said.

In Jacksonville's 26-7 victory over Washington a week ago, Taylor drew a 15-yard penalty for unsportsmanlike conduct for gesturing after his 12-yard touchdown run late in the third quarter.
