WASHINGTON -- Even before Ryan Harrison broke his racket by spiking it on the Citi Open court or screamed "Oh, my God!" in exasperation, top-seeded Juan Martin del Potro was feeling pretty good about the way things were going Thursday. And they kept improving for the 2009 U.S. Open champion. Back in action after nearly a month off, del Potro won twice in a span of about 7 1/2 hours to reach the Citi Open quarterfinals. Del Potro started by winning a rain-postponed match against 107th-ranked American Harrison 6-1, 7-5, then returned to the court under the lights at night to defeat 14th-seeded Bernard Tomic of Australia 6-3, 6-3. Each lasted about 70 minutes. "Really good day," del Potro said, smiling as he leaned back in his chair and stretched out his legs. "The match against Tomic was a little better than the first one." Del Potro, who received a first-round bye, is 11-1 at the hard-court tournament in Washington, where he won titles in 2008 and 2009. The Argentine, No. 7 in the ATP rankings, hadnt competed since July 5, when he was eliminated in five sets by No. 1 Novak Djokovic in 4 hours, 43 minutes, the longest semifinal in Wimbledon history. "I was training hard before coming here," said del Potro, who will face No. 7-seeded Kevin Anderson, also a winner twice Thursday. Anderson eliminated James Duckworth 6-3, 3-6, 6-4, then beat Mardy Fish of the United States 7-6 (2), 6-1. Before that match finished, Fishs withdrawal from next weeks tournament in Montreal was announced; the event said he pulled out for personal reasons. "Its hard for me, right now, to come out and just play every single week," said Fish, who has missed time the past two seasons while dealing with a heart condition. "I still know I have a long ways to go to get back to where Id like to be and where I was, maybe, 12 months ago," he added. The other mens quarterfinals are No. 8 John Isner against No. 16 Marcos Baghdatis, No. 3 Tommy Haas against No. 11 Grigor Dimitrov, and Marinko Matosevic against Dmitry Tursunov. Matosevic beat No. 4 Milos Raonic of Canada 7-5, 7-6 (7); Baghdatis surprised No. 2 Kei Nishikori of Japan 6-1, 6-2; the 35-year-old Haas finished off a second-round match suspended overnight in the third set, then also won Thursdays last match, 6-4, 4-6, 7-5 against No. 13 Ivan Dodig, wrapping it up after midnight. Del Potro said his left knee felt fine; he wasnt wearing any sort of wrap the way he did at the All England Club after hyperextending it on a fall during a match. "You never know" how the knee will hold up, said del Potros coach, Franco Davin. "For now, its OK." Harrison was ranked inside the top 50 last season and is widely seen as the next top American male player. "He has good potential. He serves well. He plays well on hard courts. But sometimes he looks young," said del Potro, who was a couple of weeks shy of his 21st birthday when he won the U.S. Open. "Hes still 21. He needs to learn a few things to become a better player in the future." Harrison trailed 4-0 after only 11 minutes. Both men hit serves at the considerable speed of 130 mph, but the difference was that once the ball was in play, del Potros groundstrokes were far more consistent. "Sometimes you go out there and for whatever reason, its not feeling as well as you want it to," said Harrison, 0-18 against top-10 players. "The best guys, whenever they see someones off, they just press you, and they just make you feel like youre under duress all the time." After pushing a forehand long to get broken at 3-0, Harrison smashed his equipment, earning a warning from the chair umpire for racket abuse. During a particularly rough stretch from late in the first set to early in the second, Harrison dropped 13 consecutive points, a drought that ended right after he dumped a backhand in the net, looked to the sky and yelled. From there, he played evenly against del Potro, until getting broken in the last game. Del Potro thinks Harrisons histrionics help foes. "Its easier for us, because we ... (see) our opponent really, really low," del Potro said. Three other American men joined Harrison on the way out: No. 6-seeded Sam Querrey, Jack Sock and Tim Smyczek. In womens action, the only seeded player to lose was No. 8 Madison Keys of the United States, who failed to convert two match points and bowed out against Monica Niculescu 6-1, 2-6, 7-6 (6). The womens quarterfinals are No. 1-seeded Angelique Kerber vs. No. 7 Magdalena Rybarikova, No. 3 Ekaterina Makarova vs. Niculescu, No. 4 Alize Cornet vs. Sorana Cirstea, and Andrea Petkovic vs. Paula Ormaechea. The most unusual ending to a match Thursday came when Olga Puchkova of Russia was defaulted by the WTA supervisor after hitting a line judge in the knee with a ball between points. Trailing Ormaechea 3-6, 6-3, 4-1, Puchkova was forced to forfeit even though she said it was an accident.

The recently retired Stern was elected Friday to the Naismith Memorial Basketball Hall of Fame and will be enshrined with the class of 2014 on Aug. COLLEGE STATION, Texas -- When Daeshon Hall lined up as a freshman defensive end for Texas A&M in 2013, the 6-foot-6 former basketball player wasnt much of a threat, tipping the scales at just over 200 pounds.Four years and about 60 pounds later, Hall has morphed into a star for the eighth-ranked Aggies . And his performance in their win over South Carolina on Saturday when fellow defensive end and likely first-round draft pick Myles Garrett was out with a leg injury earned Hall SEC defensive lineman of the week honors.As the Aggies prepare to host No. 9 Tennessee in a matchup of unbeaten teams on Saturday, theyll need another big game from Hall, especially if Garrett sits out again. Coach Kevin Sumlin refused to give any information on Garretts health on Tuesday.Hall had two quarterback hits, six tackles, two sacks and 3 1/2 tackles for losses against the Gamecocks. His work left him with a team-leading 8 1/2 tackles for losses and his five sacks tie Garrett for the team lead.Sumlin said the key to Halls improvement comes down to the work hes put in to bulk up to a size appropriate for playing on the defensive line. He said Hall shouldnt have played as a freshman, but that it was a necessity because they didnt have anyone else to do it.Should have redshirted, but we had to play him, Sumlin said. Four years later all that experience is a big deal. Size is a big deal. Strength is a big deal. Hes a developmental player. Happy hes hung in there. Hes a tough guy. Last week he was fabulous.Hall shakes his head when aasked about how difficult it was to pack on the pounds.dddddddddddd.I ate a crazy amount of food, but I had a high metabolism so I would start off heavy but it would burn off, Hall said. This year Im doing a real good job of keeping and maintaining my weight.Hall made a big leap last season when he had a career-high seven sacks and 14 + tackles for losses, but as his weight dipped late in the season, there were again questions about his size. Hes aware that people have talked about his lanky frame since he arrived in College Station, and hopes his detractors see the work hes put in to become a force for Texas A&Ms defense.People can see that Im serious about it, he said. I was trying to change peoples mindset about things.Though Hall is often overshadowed by Garrett, who led the SEC with 12 1/2 sacks last season, he is a big reason why the Aggies lead the nation with 50 tackles for losses this season. But Hall deflected praise for his contribution, instead raving about the work of defensive coordinator John Chavis.He does a great job, Hall said. Its a pressure defense and coach Chavis always puts us in great position to make plays.He also shook off questions about whether it was nice not to play in the shadow of Garrett last week.Just try to play hard for Myles, play hard for everybody. ... If somebody goes down we feel like anybody thats behind us can play and take the spot, he said. ' ' '
