KEY BISCAYNE, Fla. — Andy Roddick whacked one last thunderous serve to finally beat Roger Federer, then slowly walked to the net with his head down, as if unsure how to celebrate such a rare achievement.

With an almost flawless performance, Roddick ended a streak of 11 consecutive losses against his nemesis at the Sony Ericsson Open. Roddick dominated with his serve and took advantage of Federer’s suddenly shaky play down the stretch to win, 7-6 (4), 4-6, 6-3 in the quarterfinals.

In the women’s semifinals, Serena Williams overcame a slow start to outlast Svetlana Kuznetsova 3-6, 7-5, 6-3. Williams needs one more win for her fifth Key Biscayne title and second in a row.

Her opponent Saturday will be No. 4-seeded Jelena Jankovic, who beat No. 19 Vera Zvonareva 6-1, 6-4.

Roddick improved to 2-15 against Federer, who came into the tournament hoping to quell talk that his game is in decline. Slowed by mononucleosis early in the year, the top-ranked Federer has yet to reach a final in 2008, making this his worst start since 2000.

Roddick’s opponent in the semifinals will be No. 4 Nikolay Davydenko, who beat unseeded Janko Tipsarevic 6-2, 6-1.

Scott shoots course-record 63

HUMBLE, Texas — Defending champion Adam Scott overcame a fever and swollen glands around his throat, shooting a course-record 9-under 63 in calm early conditions for a share of the Houston Open lead.

Johnson Wagner matched Scott’s 63 late in the day. Wagner also shared the first-round lead last year and shared the previous Tournament Course at Redstone record (64) with Bubba Watson.

Charley Hoffman was two behind the leaders after a 65, and Steve Stricker was three back. Phil Mickelson, one of several top players using Houston as a tuneup for next week’s Masters, shot a 72 in the afternoon, when blustery wind produced higher scores.

COLLEGE BASKETBALL

Ohio State wins NITtitle

NEW YORK — A year removed from a loss in the national title game, Ohio State has a championship trophy to carry home.

Nevermind that it’s from the NIT. Jamar Butler and his buddies couldn’t care less.

Butler had 19 points and eight assists in his final college game, leading the Buckeyes to a 92-85 win over Massachusetts and prompting the victory celebration inside Madison Square Garden that they couldn’t have last year in Atlanta.

Kosta Koufos added 22 points in earning the tournament’s most outstanding player award. Evan Turner finished with 20 for the Buckeyes (24-13), who reached the preseason NIT title game but were run out of the Garden by Texas A&M.

Ricky Harris scored 27 for UMass (25-11), hitting three 3-pointers in the closing minutes to help the Minutemen stay close.

Loyola Marymount expected to hire Portland assistant

LOS ANGELES — Loyola Marymount is expected to announce the hiring of former UNLV basketball coach Bill Bayno on Friday, according to a person with knowledge of the move.

The hiring, first reported by the Los Angeles Times on its Web site, was confirmed to The Associated Press on condition of anonymity because the school had not made a formal announcement.

Bayno, currently an assistant with the Portland Trail Blazers, guided UNLV to a 95-65 record and two NCAA tournament appearances as the Rebels’ coach from 1995-2000.

He was fired during the 2000-2001 season after allegations that he had broken rules in the recruiting of Lamar Odom in 1996 and 1997. But the NCAA cleared him of wrongdoing, and he filed a wrongful termination lawsuit and received a settlement from UNLV.

Bayno, who earlier spent seven assistants on John Calipari’s staff at Massachusetts, replaces Rodney Tention as the Lions’ coach. Tention resigned after LMU went 30-61 over three seasons.

Anderson will test draft waters

BERKELEY, Calif. — California sophomore forward Ryan Anderson has decided to test his NBA value by declaring for the draft Thursday without signing with an agent.

The decision gives Anderson the opportunity to work out at his own expense for NBA teams to gauge where he would be drafted before making a final decision. Anderson has until June 16 to decide whether to remain in the draft or return to school.

He is projected by draft analysts as a borderline first-round pick. How that status changes in the next two months will decide what Anderson ultimately will do.

Anderson is an excellent outside shooter for his size and also has good post moves. But there are questions about his strength, athleticism and defense.

The 6-foot-10 Anderson was an all-Pac-10 selection this season, leading the conference in scoring at 21.1 points per game and ranking third in rebounding at 9.9.

His 1,236 points are the most by any Cal player after his sophomore year and the 16th most in school history.

Jaguars give Del Rio extension

JACKSONVILLE, Fla. — Jacksonville Jaguars coach Jack Del Rio signed a five-year contract extension, a reward for winning his first playoff game.

Del Rio’s salary was not disclosed, but it was believed to be a significant jump from the original five-year, $6.5 million contract he signed in 2003.

The Jaguars were 11-5 last season, beat Pittsburgh in the first round of the playoffs and then ended the season with a 31-20 loss at New England.
