Roger Federer ousted in German semifinal

Roger Federer lost to Argentine qualifier Federico Delbonis, 7-6 (7), 7-6 (4), Saturday in the semifinals of the German Tennis Championships at Hamburg.

Federer, a four-time champion in Hamburg, was outplayed by the 114th-ranked left-hander, who advanced to his first career final.

Federer took a wild card for Hamburg after losing in the second round at Wimbledon.

In the final, Delbonis will play Fabio Fognini of Italy. Fognini defeated third-seeded Nicolas Almagro of Spain, 6-4, 7-6 (1).

Serena Williams defeated Klara Zakopalova, 6-0, 6-4, in the semifinals of the Swedish Open at Bastad.

In the other semifinal, Sweden’s Johanna Larsson rallied to overpower Italy’s Flavia Pennetta, 2-6, 6-3, 6-4.

Williams will meet Larsson in Sunday’s final of the clay-court tournament.

Hometown favorite Alejandro Falla advanced to the Claro Open Colombia final, beating Canada’s Vasek Pospisil, 6-7 (4), 6-3, 6-4.

Falla, a Bogota resident, is seeking his first ATP Tour title. The 29-year-old left-hander will face Croatia’s Ivo Karlovic on Sunday.

Karlovic beat second-seeded Kevin Anderson of South Africa, 6-4, 6-7 (4), 6-3.

Clippers, Mullens reach agreement

The Clippers and free-agent center Byron Mullens reached agreement on a two-year contract Saturday, according to NBA executives who were not authorized to speak publicly on the matter.

Mullens’ deal is worth about $1 million per season. He can opt out of the contract after one season.

Mullens is expected to sign his contract with the Clippers on Monday or Tuesday.

The 7-foot Mullens averaged 10.6 points and 6.4 rebounds per game last season with Charlotte. He shot 38.5% from the field, 31.7% from three-point range.

Adding Mullens gives the Clippers three centers, the other two being DeAndre Jordan and Ryan Hollins.

That means the Clippers probably won’t be interested in signing free-agent center Marcus Camby, the NBA executives said.

Two tied for lead in PGA Tour event

Nicholas Thompson and Daniel Summerhays are tied for the lead going into the final round of the Sanderson Farms Championship at Madison, Miss.

Summerhays waited out a rain delay of 1 hour 17 minutes before making his final 19-foot putt for birdie, finishing with a three-under-par 69. He also led last week going into the final round of the John Deere Classic before finishing fourth.

Thompson bogeyed his first hole in the third round but was nearly flawless after that with a 65 to reach 17 under.

Spain’s Beatriz Recari birdied the two closing par fives to catch Paula Creamer atop the leaderboard through 54 holes in the Marathon Classic at Sylvania, Ohio.

Recari, a two-time winner on the LPGA tour, matched Creamer’s four-under 67. Both are at 12-under 201.

Rising American teen Lexi Thompson had a 67 and, along with Jacqui Concolino and Japan’s Chie Arimura, was three shots back.

Top-ranked Inbee Park, chasing her seventh win of the season, sagged to a 73.

New York Giants safety Will Hill was suspended for four games by the NFL for violating the league’s substance abuse policy, his second drug suspension in two years.

Hill will sit out the first four games of New York’s season, and be eligible to return in time for the Oct. 6 game against Philadelphia. He is still allowed to take part in training camp and exhibition games.

He was suspended last year for violating the league’s performance-enhancing-drug policy, testing positive for Adderall.

Rejecting claims made in a lawsuit concerning concussions, the NCAA said that it has taken steps to protect student-athletes from head injuries and that player safety is among the college sports association’s core principles.

Attorneys suing the NCAA over its handling of head injuries asked a federal judge Friday to let them expand the lawsuit to include thousands of plaintiffs nationwide. The motion seeking class-action status was filed in U.S. District Court in Chicago, where the original lawsuit was filed in 2011 on behalf of former Eastern Illinois football player Adrian Arrington and several other former athletes.
