Peirsol sets world mark in 200 backstroke

Aaron Peirsol broke the world record in the 200-meter backstroke at the U.S. nationals Saturday night in Indianapolis, beating previous owner Ryan Lochte and lowering his second world mark in three days.

The Olympic silver medalist touched in 1 minute, 53.08 seconds, bettering Olympic champion Lochte's old mark of 1:53.94 set in Beijing.

Lochte was under his world-record pace in the opening 50 meters before Peirsol took over for good. Peirsol dipped a full second under the mark after 150 meters while wearing an Arena X-Glide suit.

Peirsol reclaimed his 100 backstroke world mark Wednesday.

Cullen Jones lowered the American record in a 50 freestyle swim-off, touching in 21.41 seconds. That bettered the previous record of 21.47 set by Garrett Weber-Gale at last year's Olympic trials.

Jones edged Weber-Gale in the one-on-one race for the second spot in the event at worlds this month. Weber-Gale was clocked in 21.70.

Jones' time was faster than what Nathan Adrian swam in winning the 50 Thursday night, when Jones and Weber-Gale tied for second at 21.55. Adrian won in 21.52

Point guard Kidd re-signs with Mavs

The Dallas Mavericks have re-signed Jason Kidd.

The team announced that the free-agent point guard signed, five days after owner Mark Cuban confirmed that Kidd was returning. Kidd agreed to a three-year contract worth more than $25 million.

The 37-year-old Kidd could finish his career where it started in 1994 -- with the Mavericks. The No. 2 pick out of California returned to Dallas in a trade last year with New Jersey, where he made two trips to the NBA Finals with the Nets.

Also: The Oklahoma City Thunder signed guard James Harden, the third overall pick in the draft.

Harden was a first-team All-American and the Pac-10 player of the year after averaging 20.1 points, 5.6 rebounds and 4.2 assists during his sophomore season at Arizona State.

First-round draft pick Jordan Hill signed with the New York Knicks. Hill, from Arizona, was the eighth overall pick in the draft.
