The Chicago Cubs capped a stunning eight days by agreeing to terms on a multiyear contract with prized free-agent outfielder Jason Heyward, various news organizations reported Friday.

Heyward and the Cubs agreed on a $184 million, eight-year contract, according to a person familiar with the negotiations.

The agreement with the three-time Gold Glove winner is the latest in a series of big moves by the Cubs.

Chicago also has added pitchers John Lackey and Adam Warren along with infielder Ben Zobrist. Lackey, like Heyward, left the rival Cardinals for the Cubs and figures to be Chicago's No. 3 starter.

An All-Star in 2010, Heyward, 26, hit .293 with 13 homers and 60 RBI this year, helping St. Louis win the NL Central. He spent his first five big league seasons with Atlanta.

Heyward has a .268 career batting average but has hit more than 18 homers just once.

Blue Jays sign infielder Barney

•Infielder Darwin Barney agreed to a $1.05 million, one-year contract with the Toronto Blue Jays. Barney, 30, hit .304 with two homers in 15 games for Toronto after being acquired from the Dodgers on Sept. 13. He won an NL Gold Glove at second base in 2012 with the Chicago Cubs.

•Autopsy results show the death of former Atlanta Braves and Los Angeles Angels pitcher Tommy Hanson was caused by cocaine and alcohol use. Hanson died Nov. 9 at age 29 in a friend's home in Newnan, Ga.

Doping

Russians will face extra testing

Russia has been told what it will take to get its track and field athletes back in the Olympics, and it entails extra doping tests.

The country's track federation was suspended last month after it was accused of operating a state-sponsored doping program. The suspension could keep Russia out of next year's Olympics in Rio de Janeiro, but the IAAF said that even if the ban is lifted athletes cannot be readmitted to international competition without "at least three no-notice out-of-competition tests."

There are extra requirements in place for endurance events, which have seen dozens of Russians banned for doping in recent years.

"The conditions we have announced leave no room for doubt," IAAF President Sebastian Coe said. "Russia must demonstrate verifiable change across a range of criteria."

Tennis

Federer, Hingis to team up at Rio

Roger Federer says he'll team up with Martina Hingis for Switzerland in mixed doubles at next year's Rio Olympics.

Federer wrote Friday on Twitter that he is "really excited" about the pairing, and posted a photograph of the two tennis stars, who are beloved in their home country, from what he said was 15 years ago.

Federer is 34, Hingis is 35.

Federer has won a record 17 Grand Slam singles championships. He also has won two Olympic medals: silver in singles at London in 2012, and gold in doubles with Stan Wawrinka at Beijing in 2008.

Hingis owns 20 major championships — five in singles, 11 in women's doubles, four in mixed doubles. She has retired from singles but still competes in doubles, winning women's and mixed titles at the U.S. Open in September.
