RIO DE JANEIRO -- Juan Martin del Potro had doubted he could win the six matches in eight days needed for another Olympic medal.After all, this is a player who went 2+ years between majors because of three left wrist surgeries before he entered Wimbledon this year. But now that the 2009 U.S. Open champion is into the quarterfinals in Rio de Janeiro, he can start dreaming a bit about those medal rounds.Del Potro came from behind Thursday to beat 117th-ranked Taro Daniel of Japan 6-7 (4), 6-1, 6-2, looking strong in the final set of a match that lasted 2 hours, 12 minutes.The Argentine stunned top-ranked Novak Djokovic in the first round, part of nearly 7 hours on court between singles and doubles in a span of about 25 hours Sunday and Monday. He had a scheduled day off Tuesday, then the match with Daniel was postponed Wednesday by rain, providing some extra rest.This has been a great tournament, a great week for me already, del Potro said. Im looking forward to go far, trying to fight for one medal. Im still playing well, but the next round is going to be a really difficult match for me.His opponent will be 10th-seeded Roberto Bautista Agut of Spain, whose movement on the baseline could be a challenge. But as del Potro and his forehand showed against Djokovic, hes one of the best in the world when hes healthy and fit -- even now with his surgically repaired wrist causing problems for his two-handed backhand.Daniel actually has a better ranking than del Potro, who is 141st in the world after his injury layoffs. But whereas the 23-year-old Daniel had never defeated a top-30 player before his first-round victory over 25th-ranked Jack Sock, del Potro has beaten Roger Federer in a major final and Djokovic for bronze at the 2012 London Games, among other big wins in his career.Still, del Potro said of Thursdays match: I had doubts in the beginning, and I got myself into a mess.He had 22 unforced errors in the first set and 15 combined in the last two.I started the second set angry, he said.When del Potro went up two breaks in the third set with a winner on a volley that was more self-defense than anything, he pumped both fists and screamed toward the stands, which were dotted with Argentine flags.In the end, he said, the crowd helped me a lot to survive.

They know this game is about the seniors.

I cant say enough about him.Boyette Jr., a senior, said it leaves a bitter taste in his mouth to think another head coach could come to Texas next season and reap the benefits of Strongs three years of building.If they hit the jackpot, they go a national championship, win the Big 12, theyll know who got em there, Boyette Jr. said.Strong is 16-20 overall and 12-14 in Big 12 play in three seasons with the Longhorns. If he coaches Friday against TCU, Strong will clinch either a bowl bid or his third seven-loss season.Strong said Monday that he wants to return next season and feels that a young Texas team has a lot of upside.If he is fired, however, Strong will be owed a $10.7 million buyout for the remaining two years on his contract, a fee that would be reduced if he takes another job.Strongs situation came to a head after Texas lost 24-21 in overtime to a Kansas team that was 1-9 and had lost its past 19 Big 12 games.ESPN staff writer Max Olson contributed to this report. cheap falcons jerseys cheap ravens jerseys cheap bills jerseys cheap bears jerseys cheap bengals jerseys cheap cowboys jerseys cheap lions jerseys cheap texans jerseys cheap colts jerseys cheap jaguars jerseys cheap chiefs jerseys cheap rams jerseys cheap dolphins jerseys cheap vikings jerseys cheap saints jerseys cheap giants jerseys cheap jets jerseys cheap eagles jerseys cheap steelers jerseys cheap 49ers jerseys ' ' '
