CHICAGO - Federal prosecutors moved Monday to delay indefinitely the sentencing of convicted fundraiser Antoin "Tony" Rezko, sending their strongest hint yet that he is ready to spill his political secrets.

Speculation has simmered for weeks that the key fundraiser for Gov. Rod Blagojevich and Sen. Barack Obama was whispering what he knows about corruption in Illinois government to federal prosecutors in hopes of getting a lighter sentence.

U.S. District Judge Amy J. St. Eve had set Sept. 3 as a firm date for sentencing Rezko on his conviction for launching a $7 million scheme to use his clout with the Blagojevich administration to squeeze kickbacks out of a contractor and seven money management firms wanting to do business with the state.

CHICAGO - B.J. Upton and these Tampa Bay Rays are headed home - to get ready for the American League championship series.

Worst in the majors last year, the Rays will play for a spot in the World Series after finishing off the Chicago White Sox 6-2 Monday in Game 4 of the AL playoffs.

Upton homered twice, Andy Sonnanstine pitched a solid 5 2-3 innings and manager Joe Maddon's surprising Rays won 3-1 in the best-of-five series - their first trip to the postseason.
