New York — Ohio State moved into second in the College Football Playoff rankings behind Alabama, with Michigan and Clemson still in the top four after losing for the first time this season.

Louisville was fifth, and Washington dropped from fourth to sixth after its first loss.

“The margin of separation between teams two and six was very small,” said selection committee Chairman Kirby Hocutt, who is also the athletic director at Texas Tech.

Clemson, Michigan and Washington — the Nos. 2, 3 and 4 teams in last week’s rankings — all lost to unranked teams on Saturday. The Wolverines, who have three victories against teams in the selection committee’s top 10, did not move after losing to Iowa.

The Tigers ended up dropping two spots to No. 4 after losing to Pittsburgh.

Wisconsin was seventh and Penn State eighth, giving the Big Ten four teams in the top 10. Oklahoma was the highest rated Big 12 team at nine and Colorado was 10th.

Djokovic to ATP Semis

London — Novak Djokovic edged a bit closer to the year-end No. 1 ranking, beating Milos Raonic 7-6 (6), 7-6 (5) on Tuesday to qualify for the semifinals of the ATP finals.

Djokovic is 2-0 at the season-ending tournament, and will retake the top ranking from Andy Murray if he does better this week.

Murray is 1-0 so far, and plays his second match today against Kei Nishikori.

Djokovic never looked at ease in his second match at the O2 Arena, but he was able to hang on through two tough tiebreakers to earn the victory.

The second-ranked Serb saved three break points in the first set, and managed to go up a break twice in the second set but Raonic responded each time.

In the early match, Dominic Thiem went through another second-set letdown before putting things right to give himself a chance to advance.

The eighth-seeded Austrian, who is making his debut at the season-ending tournament, held on to beat Gael Monfils 6-3, 1-6, 6-4, making him 1-1 in the round robin.

Hall of Famer Mulloy Dies at Age 102

Miami — Gardnar Mulloy, a member of the International Tennis Hall of Fame who won 129 U.S. national titles, has died at age 102.

His wife, Jackie, says the longtime Miami resident died Monday night.

Mulloy won five Grand Slam doubles titles, was ranked No. 1 in the United States in 1952 and started the University of Miami tennis program. He swept United States Tennis Association grand slams in three age groups: 45s, 70s and 80s.

Mulloy, who served in the Navy during World War II, was 31 when the war ended, and his tennis career had barely begun. At age 43, he won the Wimbledon doubles title with Budge Patty and helped the U.S. Davis Cup team reach the final.

He played competitively into his 90s and would have turned 103 on Nov. 22.
