Rita Jeptoo, a three-time winner of the Boston Marathon and two-time Chicago Marathon champion, was handed a two-year doping ban Friday in a case that has cast a shadow over Kenya's famed distance runners.

Jeptoo tested positive for the blood-booster EPO in an out-of-competition test last September, a few weeks before winning her second consecutive Chicago Marathon title. Both the "A" and "B" samples were positive.

Athletics Kenya said Friday that Jeptoo was suspended from all competition until Oct. 29, 2016. The sanction rules her out of this year's world championships in Beijing and next year's OIympics in Rio de Janeiro.

Jeptoo, 33, is the biggest name among dozens of Kenyan athletes who have failed drug tests in recent years. The World Anti-Doping Agency has urged Kenya to step up its drug-testing program.

Paralyzed Van Dyken gets back to work

Six-time Olympic gold medalist swimmer Amy Van Dyken returned to work as a broadcaster with the Pac-12 Network nearly eight months after an all-terrain vehicle accident left her paralyzed from the waist down.

Van Dyken flew into the Bay Area from Arizona to call the USC-California women's swim meet in Berkeley.

"I'm going for more than a gold medal right now," she said. "I'm going to get my life back. So, suck it up, buttercup, and get it done."

Academics stressed for Buckeyes A.D.

Ohio State's board of trustees altered the contract of athletic director Gene Smith to pay him incentives for academic performance and career development instead of for Big Ten championships.

Smith's previous contract paid him an extra $18,000 for each Big Ten title won by Ohio State teams and individuals.

Now he's eligible for bonuses that can add up to $130,000 per year as before, but they'll be paid when teams meet cumulative grade-point average goals and when athletes win academic awards. Starting in 2016, he can get a bonus for the annual percentage of athletes who, after graduation, get jobs in which degrees are required.

Baker had Tommy John elbow surgery in 2012 and mostly pitched out of the bullpen last year for the Rangers.
