AUSTIN, Texas -- Toto Wolff says Mercedes faces a very stressful final three races of the season as it attempts to ensure 100 percent reliability for both its drivers.Nico Rosberg leads teammate Lewis Hamilton by 26 points, with 75 left to play for over the remaining three rounds. Hamiltons campaign has been plagued by reliability issues, including an engine failure while leading the Malaysian Grand Prix last month, but he took his first victory since July at the weekends U.S. Grand Prix.It is very stressful for the guys in the garage because there is a lot of responsibility and pressure on them, and everything that is being said, consciously or unconsciously, puts even more pressure, Wolff said. Thats not the right thing to do. Our job needs to be to take pressure away because responsibility and accountability stays there anyway. This is how these guys work.Hamilton admits he has been haunted by the failure in Malaysia and spent much of Sundays U.S. Grand Prix in fear of a repeat.Every single lap I was thinking something might happen, Hamilton said. When I get on that back straight I was petrified. It [the engine] has a beautiful ring to it, but it had a beautiful ring in Malaysia.I was haunted by that, dreading that would happen so I am so grateful that it didnt. It wasnt until I got over the line that I was like thank you, I am so happy, rubbing the cockpit - thank you for getting me there.Wolff confirmed Mercedes had opted not to pursue an additional upgrade to its engine, meaning Hamilton and Rosberg both have the same spec engine for the rest of the season after the German took a new unit this weekend.We have decided not to bring the latest spec engine and upgrades to every single Mercedes customer, not just us. We are running that specification to what it can run, so that hasnt changed.Asked if there had been any engine worries in Austin, Wolff added: It is never plain sailing. It was as good as it can be with the engine. I understand that Malaysia came out of nowhere and Malaysia swings with all of us. That little trauma is going to remain for a while.

MEMPHIS, Tenn. -- Marc Gasols surgically repaired right foot is healthy, and the Memphis Grizzlies center insists hes back -- perhaps better than ever.Point guard Mike Conley is healthy too, his aching Achilles a distant memory. Jarell Martins own left foot is as healthy as its been in a long time.Chandler Parsons, the Grizzlies big free agent signee this summer , is the only person still recovering from his own knee surgery as the Grizzlies held media day Monday. Its a welcome change for a franchise that set a dubious NBA mark last season playing 28 different players due to injuries that ravaged the roster, giving new coach David Fizdale a healthy roster for the start of training camp Tuesday.The Grizzlies still reached the playoffs only to be swept by the San Antonio Spurs.Last year, man it was tough with all the injuries, especially the playoffs not having a full-strength team, so it was very tough, forward Zach Randolph said Monday. Now we all healthy, and now we looking at the big picture and thats getting a championship and getting a ring.Losing Gasol was the biggest hit. Memphis was fifth in the Western Conference on Feb. 8 when Gasol last played and slipped to the No. 7 seed as the injuries mounted. He had surgery to repair a non-displaced fracture in the navicular bone of his right foot Feb. 20, starting a long rehabilitation process to return him to the court.Recovery kept Gasol from playing for Spain during the Olympics, though the center wanted to play. He followed all the doctors orders and stuck with his rehabilitation. Gasol said hes never felt any discomfort in his foot, which makes him confident the repair worked. Hes now ready to help lead the Grizzlies back to the Western Conference finals for the first time since 2013 and even further to a place Memphis has never been: the NBA FFinals.ddddddddddddIm confident that I have the capability of not just being the same player, but better, Gasol said. Better player, more productive, more consistent. Hopefully a better rebounder. ... Its going to be a challenge for me, but Im up for it. Im up for any challenge. I love challenges, and this years going to be another one.Guard Tony Allen said Gasol looks like hes added to his game, noting the man nicknamed Big Spain knocked down six straight 3s in a pickup game recently.Being healthy isnt the only difference for Memphis from the end of last season. The Grizzlies start training camp Tuesday with a new coach in Fizdale , a long-time Miami Heat assistant who Memphis hired in late May after firing Dave Joerger who was then hired by Sacramento.The Grizzlies also announced Monday they hired a new medical director in Allen Gruver, promoted Jim Scholler to head athletic trainer and added Eric Oetter as director of performance. Conley said the Grizzlies have bolstered the staff to help players, even adding massage therapists to help with recovery.Fizdale also suggested to the Grizzlies that they show up a couple weeks early and play together to start building chemistry and conditioning. Fizdale said he couldnt make them do it, and he liked how they listened. Managing Gasols minutes will be a big focus for Fizdale who plans to pull him early from some practices and keep him out of some games through the season.Im definitely going to preserve him, Fizdale said. I dont want to kill him throughout the year and dont have him for the playoffs so itll be very mindful of how I attack him coming back from an injury.---Follow Teresa M.
