Rafa Cabrera Bello, just back from Olympics, leads PGA Tour event

Rested after the Rio Olympics, Rafa Cabrera Bello shot a 7-under 63 on Thursday in the PGA Tour's Wyndham Championship in Greensboro, N.C. He shares the first-round lead with Kevin Na.

Cabrera Bello eagled the par-5 fifth and closed the bogey-free round with a birdie on Sedgefield's par-4 ninth. On Sunday, the 32-year-old Spaniard tied for fifth in Rio.

"Last week was a big adrenaline week," Cabrera Bello said. "It was the first time I was really not playing for myself, just playing for my country, and obviously it's a huge honor, but also big responsibility."

The four-time European Tour winner is trying to stay in position for a Ryder Cup spot, with more ranking points available in North Carolina than the European event in the Czech Republic. The shorter travel also played a role.

"It was going to be easier to travel south to north than from Rio to Czech Republic, jet lag-wise," he said.

Jim Furyk had a 66 in his first round since shooting the first 58 in PGA Tour history two weeks ago.

Michigan sophomore Nick Carlson won two matches on the 19th hole at Oakland Hills in Bloomfield Hills, Mich., to advance to the U.S. Amateur quarterfinals. He beat British Amateur champion Scott Gregory of England in the morning round of 32 and topped Thailand's KK Limbhasut in the afternoon round of 16. Carlson will play Illinois junior Dylan Meyer on Saturday. Meyer also won twice Friday.

He's fresh off an Olympic run that produced a gold medal in doubles, and he was feeling pain all over.

"Too tired," he said. "Elbow, shoulder. Two and a half months without competing and especially without practicing, and to do what I did in the Olympics and come here — too much."

Colleges: Tennessee athletic director Dave Hart said he will retire next summer, the announcement coming six weeks after the school reached a $2.48 million settlement in a Title IX lawsuit.

Paralympics: The Rio Olympics organizing committee can take public money to put on the upcoming Paralympic Games, a judge ruled. It amounts to a government bailout, an embarrassment to Rio organizers.
