Federer overcomes slight stumble

Tennis: Chasing a shot, Roger Federer caught his right shoe in the French Open’s red clay, twisting that foot awkwardly and tumbling to the ground at Paris’ Roland Garros.

Soon enough, he was in a real rut, in danger of his earliest exit from a Grand Slam tournament in nine years.

Federer regrouped and restored order eventually, coming back from a two-sets-to-one deficit to beat 15th-seeded Gilles Simon of France 6-1, 4-6, 2-6, 6-2, 6-3 Sunday in the fourth round to reach his 36th consecutive major quarterfinal.

The largest comeback of the day, however, belonged to 32nd-seeded Tommy Robredo of Spain. Robredo overcame a two-set deficit, defeating No. 11 Nicolas Almagro 6-7 (5), 3-6, 6-4, 6-4, 6-4. Robredo trailed 4-1 in the third set, 4-2 in the fourth and 2-0 in the fifth.

Robredo’s quarterfinal will be against another Spaniard, No. 4 David Ferrer, who eliminated No. 23 Kevin Anderson of South Africa 6-3, 6-1, 6-1.

No. 6-seeded Jo-Wilfried Tsonga of France will face Federer, getting past Viktor Troicki 6-3, 6-3, 6-3. Tsonga is 3-9 against Federer.

For the women, No. 1 Serena Williams beat No. 15 Roberta Vinci 6-1, 6-3 to extend her winning streak to 28 and set up a quarterfinal against Svetlana Kuznetsova, the 2009 champion who is unseeded this year and defeated No. 8 Angelique Kerber 6-4, 4-6, 6-3.

Fifth-seeded Sara Errani overcame breathing problems to beat No. 20 Carla Suarez Navarro 5-7, 6-4, 6-3. Errani will face 2012 Wimbledon runner-up Agnieszka Radwanska, who eliminated 2008 French Open champion Ana Ivanovic 6-2, 6-4.

• Ohio State president issues apology: Gordon Gee, the president of Ohio State University, has apologized to the Big Ten conference for “hurtful remarks” he made in a “misguided attempt at humor” about some university athletic programs before Ohio State’s Athletic Council in December.

He says the Big Ten universities are “some of this country’s most highly accomplished research institutions” and he’s honored to lead a Big Ten school.

An AP report last week revealed Gee said Notre Dame wasn’t allowed to join the Big Ten because its leaders weren’t good partners. He said its Roman Catholic priests were “holy hell” on days other than Sunday and joked “those damn Catholics” can’t be trusted.

He also questioned the academic integrity of schools in the Southeastern Conference.
