The Dallas Mavericks knew they could trade Jerry Stackhouse for a key player for next season. As it turned out, a lot of teams benefited.

The Mavericks, Raptors, Grizzlies and Magic combined in a massive swap yesterday that included eight players, a draft pick and stacks of cash. The deal sent Shawn Marion to Dallas, Stackhouse to Memphis and helped seal the transaction that moved Hedo Turkoglu from Orlando to Toronto.

Among the other pieces: Forward Kris Humphries and center Nathan Jawai went from Toronto to Dallas; guard Greg Buckner moves from Memphis to Dallas; and swingmen Antoine Wright and Devean George go from Dallas to Toronto.

Memphis also received a second-round pick and cash from Toronto, while Orlando got cash from Dallas and the Raptors.

The Magic were going to lose Turkoglu anyway. After Orlando acquired Vince Carter, Turkoglu opted out of his contract and became a free agent. He'd already decided to go to Toronto, but turning his departure into a sign-and-trade helped glue together the rest of this complex puzzle.

The Mavs are no strangers to convoluted, multi-team deals, but this one was still taxing. Team owner Mark Cuban posted on his Twitter feed late Wednesday: "It's been a long day of looking at spreadsheets, reading NBA cap rules and rubbing my eyes."

It was worth the effort to Cuban because Dallas got Marion, a four-time All-Star nicknamed "The Matrix" because of his do-it-all game. The Mavs are hoping he'll be a great complement to a starting lineup featuring Dirk Nowitzki, Jason Kidd and Josh Howard.

For his career, Marion has averaged 17.8 points, 9.9 rebounds, 2.0 assists, 1.83 steals and 1.31 blocks per game.

Stackhouse was enticing because although his contract is for more than $7 million, if he's waived by mid-August he can be bought out for only $2 million. That's likely the amount of cash Memphis received.

PHELPS SETS WORLD RECORD IN 100-METER BUTTERFLY

Four months after deciding to keep swimming, Michael Phelps took ownership of a world record that had eluded him for years.

He won the 100-meter butterfly at the U.S. national championships at Indianapolis last night in 50.22 seconds, lowering Ian Crocker's mark of 50.40 set at the 2005 world championships in Montreal.

Phelps' feat came just two months after returning from a suspension that was part of the longest layoff of his career, which he considered ending when a photograph of him using a marijuana pipe surfaced.

"It really shows anything can happen if you put your mind to it," Phelps said. "It feels good to get a best time."

Phelps, a 14-time Olympic gold medalist, pulled clear down the stretch to beat Tyler McGill, who touched in 51.06. Aaron Peirsol was third in 51.30.

NBA: The Los Angeles Clippers signed Blake Griffin, the No. 1 overall pick in the NBA draft. The team says that Griffin's deal was official, and terms were not announced. The 20-year-old center averaged 22.7 points and 14.4 rebounds last season at Oklahoma before leaving two years early to enter the draft.
