Esteban Gutierrez believes Haas can expect a reasonable step in performance at this weekends Singapore Grand Prix thanks to a new aerodynamic upgrade.The American outfit has introduced the package, which is focused on improving the VF-16s aerodynamic performance, in a bid to overhaul Toro Rosso?in the constructors championship during the remaining seven races of 2016. The update is set to be the teams final upgrade of the season, after it received the latest-spec Ferrari power unit at Monza.Gutierrez hopes Haas will be able to maximise the benefits of the upgrade around the Marina Bay Street Circuit.We have some new aerodynamic parts at the back of the car, some at the front, which still need to be evaluated but mainly the most important one is the one at the rear, Gutierrez said. The target is to attack the weaknesses of the car, mainly at the end of braking and turning the corner, so if the things work as expected as they should, it will give us more confidence to extract much more from the car. Its a really good thing to have.We have the upgraded engine from Monza, the team is pushing hard on those areas to really improve the weaknesses and I think if everything works as expected it should give us a reasonable step.Gutierrez has recorded four 11th place finishes but is yet to score a point in 2016, compared to the 28 scored by teammate Romain Grosjean which have propelled Haas up to eighth in the constructors standings in its debut campaign. The Mexican -- who achieved Haas first Q3 appearance in Formula One at the Italian Grand Prix -- admits he is feeling the pressure to score his first points in F1 since 2013.Well the pressure is there, I mean its always there. I dont think its only coming from myself. Of course I want to achieve this and I want to get them but its just the matter of having the right opportunities.Its pretty tough when people say and speak things, if you really consider taking away the races that I had all the problems in the car, the mechanical failures, things like that, and then you add all the races that I finished with the car complete, lets say -- in a good shape technically -- then thats what should be judged.

RIO DE JANEIRO -- One destroyed racket -- and one poor set -- later, Serena Williams made it safely into the third round of the Rio Olympics as she bids for a second consecutive singles gold medal.The No. 1-seeded American struggled for quite a while Monday night, before emerging with a 7-6 (5), 6-2 victory over Frances Alize Cornet, despite making 36 unforced errors and getting broken four times.I just needed to relax. I was missing shots by, literally, centimeters, and Im not really used to missing those shots, Williams said. I really had to figure out a way to adjust.Williams started well enough, taking the first three games and compiling 17 of the matchs first 21 winners. But then she dropped 5 of 6 games to fall behind 5-4.During that troublesome stretch, Williams reacted to losing two games in a row by mangling the tool of her trade, slamming it against the back of her green-and-white sideline bench before depositing it on the ground. Hardly the first time shes done that sort of thing -- and likely not the last, either.In her previous tournament, Wimbledon, Williams broke a racket after losing the opening set of a second-rounder against American Christina McHale. Williams then flung the racket so far behind her that it landed in the lap of a TV cameraman filming the match.From that point on, Williams didnt drop a set the rest of the way at the All England Club, taking 12 in a row to earn her record-tying 22nd Grand Slam title.She didnt quite generate that sort of spark Monday, 24 hours after she and older sister Venus lost an Olympic doubles match for the first time. They had been 15-0 with three golds, but that run is now over.So, too, is Cornets three-match winning streak against the younger Williams.Thats because Williams cut down on her mistakes in the second set.How?Just tried to add a little bit more spin, she explained. If its going out, maybe Im hitting it a little bit too flat.After three No. 1 seeds exited Sunday -- Serbias Novak Djokovic in mens singles, the Williams sisters in womens doubles, and Frances Nicolas Mahut and Pierre-Hugues Herbert in mens doubles -- Williams avoided that sort of result in singles. But Djokovics Olympics are over, because after he and Nenad Zimonjic lostt 6-4, 6-4 to Brazils Marcelo Melo and Bruno Soares, the 12-time major champion said he will not enter mixed doubles in Rio de Janeiro.ddddddddddddilliams singles match was touch-and-go for more than an hour. Cornet held a pair of set points in the opener but failed to convert either. Then Williams served for that set at 6-5, only to get broken at love when she double-faulted for the fifth time. In the tiebreaker, Cornet went ahead 5-4 before Williams claimed the next three points and the set.She raced to a 3-0 edge in the second set, and that was pretty much that.No tennis player ever has won two Olympic singles golds -- let alone two in a row. But Williams is not just any player, of course. Which is why it was rather remarkable that Cornet, who is ranked only 48th and never made it past the fourth round of a major in 42 appearances, entered Monday with a 4-3 record against Williams.She knows how to play me, Williams said. Every time I play her, Im not in my best shape.Joining Williams in the third round: No. 2 Angelique Kerber of Germany, No. 3 Garbine Muguruza of Spain and No. 7 Madison Keys of the U.S.Elsewhere, the man who got stuck in an elevator for 40 minutes and then beat Djokovic in singles on Sunday, Argentinas Juan Martin del Potro, got to the third round with another win in singles but lost to Spains Rafael Nadal in doubles.Del Potro produced a 6-3, 1-6, 6-3 victory over Portugals Joao Sousa, before heading back out on court with partner Maximo Gonzalez and getting beaten by Marc Lopez and Nadal 6-3, 5-7, 6-2. Add it all up, and del Potro spent nearly 7 hours on court in a span of barely 25 hours.In a tournament that began without half of the ATPs top 10, del Potro looks like someone who might be able to add another medal to his 2012 bronze.Because of injuries, del Potro went 2 1/2 years without participating in a major until Wimbledon, so one big question is what his fitness level is.Im getting better. Im in good shape, he said, but I dont know if Im prepared to play six or more matches.---Follow Howard Fendrich on Twitter at http://twitter.com/HowardFendrich ' ' '
