Roddick back today after rain delay

Tennis: His match, and his retirement, put off for at least another day, Andy Roddick stepped out of Arthur Ashe Stadium and into the drizzly night, a black jacket’s hood pulled overhead, a bag of ice soothing his right shoulder.

He’ll try to prolong his U.S. Open – and his professional tennis career – today.

Roddick’s fourth-round showdown against another past champion at Flushing Meadows, Juan Martin del Potro of Argentina, was suspended because of rain Tuesday night, with the American leading 1-0 in a first-set tiebreaker.

They were scheduled to resume today as the second match in Ashe, after four-time major champion Maria Sharapova’s quarterfinal against 2007 Wimbledon runner-up Marion Bartoli. That was halted Tuesday with Bartoli ahead 4-0.

Other matches stopped in progress, also in the first set, included defending champion Novak Djokovic against No. 18 Stanislas Wawrinka, and No. 8 Janko Tipsarevic against No. 19 Philipp Kohlschreiber.

On a day of off-and-on action because of intermittent showers, only two singles matches were completed: Top-seeded Victoria Azarenka reached her first U.S. Open semifinal by cobbling together a 6-1, 4-6, 7-6 (5) victory over defending champion Sam Stosur, and No. 4 David Ferrer reached the quarterfinals by beating No. 13 Richard Gasquet 7-5, 7-6 (2), 6-4.

Dismissed LSU star enrolls in school

College football: Tyrann Mathieu has opened a new chapter at LSU.

Whether the 2011 Heisman Trophy finalist known as the Honey Badger ever plays football for the Tigers again remains to be seen.

As Mathieu was enrolling in school for the fall semester, LSU coach Les Miles was maintaining his stance that the time is not right to speculate on the former star cornerback’s future with the program.

All that is certain at this point is that Mathieu, who was dismissed from the team Aug. 10 for failed drug tests, won’t be playing this season, which continues Saturday night with the Washington Huskies’ visit to Tiger Stadium.

When Mathieu was dismissed, Miles and LSU athletic officials said the move was required by school policies. They assumed Mathieu’s departure was permanent, for practical purposes, because he was immediately eligible to transfer to a football program in the FCS, the second tier of Division I, and also will have the option of entering the 2013 NFL draft.

However, Mathieu instead went to Houston to check himself into the Right Step recovery center run by former NBA player and coach John Lucas, who battled drug and alcohol problems during his career and now counsels others.

• Ex-Grizzly will plead guilty: The attorney for former University of Montana running back Beau Donaldson says his client plans to plead guilty to sexual intercourse without consent after reaching a plea agreement with prosecutors.

Prosecutors said Donaldson raped a female acquaintance while she slept on his couch after drinking alcohol at a Missoula party in September 2010. Court records say he acknowledged the assault during a monitored telephone conversation in December.

• North Dakota St. players face charges: Eight North Dakota State University football players, including four starters, are among 11 people charged with faking petition signatures in a scheme that will keep two well-funded initiatives off the November ballot.

Bison coach Craig Bohl said the players will be eligible to play this weekend against Colorado State and any team discipline would wait until after the criminal case was resolved.

• Man indicted in Auburn killings: A 22-year-old man has been indicted on capital murder charges in the killing of two former Auburn University football players and a third person at a pool party.

Desmonte Leonard is accused of opening fire with a .40-caliber pistol, killing the three and wounding three others at the party near the Auburn campus on June 9.

Former Auburn football players Edward Christian and Ladarious Phillips were killed along with DeMario Pitts of Opelika. Wounded were current Auburn player Eric Mack and two other men.

• Pinkett suspension increased: The Notre Dame radio network suspended former Irish running back and commentator Allen Pinkett without pay for two more games after his comments last week that teams need bad guys to give them an edge.

Pinkett had already been pulled off last Saturday’s season opener against Navy. He will now miss the games against Purdue and Michigan State.
