KANSAS CITY, Mo. -- Andy Pettitte finally stopped beating himself up long enough to look at video of his past couple of outings, subpar efforts by any stretch and certainly his own lofty standards. It turned out that all the 40-year-old left-hander needed to do was a make a couple of minor adjustments -- alter his arm angle ever so slightly, for one thing -- to get back on track. Pettitte pitched seven stellar innings Saturday night, and Vernon Wells hit a go-ahead two-run homer before making a long running catch for the final out, giving the New York Yankees a 3-2 win over the Kansas City Royals. Pettitte (4-2) allowed seven runs against Houston and only lasted five innings his last time out against Oakland. But he looked more like he did early in the season against the Royals, with a piercing cutter and pinpoint control that kept Kansas City at bay all night. "Whenever you get knocked around, its not a good feeling. You never want that doubt to creep in that youre not able to get it done," Pettitte said. "Hopefully I can continue to get sharper and sharper." Pettitte allowed only a run-scoring groundout by Lorenzo Cain and a solo homer by Billy Butler while improving to 15-3 in his career against the Royals. Kansas City hasnt beaten him in 14 starts dating to Sept. 4, 2000. "I really dont think hes forgotten how to pitch, forgotten how to throw a cutter or any of that," Yankees manager Joe Girardi said. "I always say, when youre old or overweight -- and you dont want to be both -- and youre struggling, people are always going to be saying, Is something wrong? Is something wrong? Its baseball. Everyone struggles." Everyone except Mariano Rivera, it seems. After David Robertson struck out the side in the eighth, Rivera worked around a two-out double by Salvador Perez for his 14th save. But it wasnt without some tension: Mike Moustakas hit a liner to right that landed just foul, and then scorched a pitch into the left-centre field gap that Wells tracked down on the run to end the game. It was Riveras 14th save to start the season, and his 28th straight against the Royals. It came just over a year after he tore the ACL in his right knee while shagging balls in the Kauffman Stadium outfield during batting practice. "I think Mo said it best, as an athlete, you can get hurt anywhere," Girardi said. "It just happened to be here. ... Im sure it was good for him to get out there." James Shields (2-3) was hurt by a throwing error on Moustakas at third base in the second inning that resulted in the Yankees first run. He also gave up Wells two-run shot in the fifth, moments after Butlers home run had staked Kansas City to 2-1 lead. Shields wound up going eight innings for the third time in his last four outings, and each of those times hes failed to pick up the win. He dropped to 7-15 in his career against New York. "Youve got to pitch better," Shields said. "Thats it." It was the Royals fifth loss in six games. "Andy Pettitte threw the ball great," Royals manager Ned Yost said. "Kept the ball down. Changes speeds. Hit his spots really well. We never mounted much of an attack." The bounces certainly seemed to be going the Yankees way most of the night. Travis Hafner hit a slow grounder toward first base in the fourth inning, and Shields and first baseman Eric Hosmer had trouble deciding who should grab it. Neither of them did until it was too late, and Hafner coasted across the bag for an infield single. Lyle Overbay hit another grounder in the sixth inning that Elliot Johnson fielded at second base, but only after shortstop Alcides Escobar bumped into him. The slight hiccup allowed Jayson Nix to reach second safely and Overbay to be safe at first. Meanwhile, a hard-hit ball by Moustakas leading off the seventh inning caromed off Pettittes glove and right to Robinson Cano. The Yankees second baseman made the soft toss to first, turning a potential base hit into an easy groundout. Cano had another rough night in Kansas City, though. The Yankees All-Star was booed mercilessly for the second straight night by Royals fans who no doubt still remember his decision to snub Butler for the AL squad during last years home run derby, which was hosted by the Royals as part of All-Star festivities. Cano went 0 for 4 and struck out looking in the seventh, arguing with plate umpire Mark Wegner over the third strike. First base coach Mick Kelleher got between them and Girardi also ran onto the field to make sure Cano wouldnt be tossed from the game. NOTES: The Yankees plan to use a pitcher to fill the 26th player on the roster for Mondays doubleheader at Cleveland. Girardi didnt know who it would be. ... Royals RF Jeff Francoeur was back in the starting lineup after having Friday night off. ...

SPIELBERG, Austria -- Pirelli says it may be able to lower its tyre pressure prescriptions at upcoming races if the FIAs new procedure for checking pressures has the desired effect.Since the Italian Grand Prix last year, the FIA has enforced Pirellis pressure perscriptions at each grand prix to make sure undue stress is not put through the tyres. In order to stop teams working on ways to reduce the pressures when the tyres are fitted to the car -- and therefore gain a competitive advantage -- the FIA will now check pressures before the tyres are fitted rather than when they are on the car. It is believed the new procedure will eliminate any tricks the teams found to heat up the tyres while they are checked on the car before cooling them on track to reduce the pressures.Yes we are working with them [the FIA] to improve the system of checking the prescription, Pirellis motorsport director Mario Isola said. With this new system, to check the tyres before they are fitted on the car, the pressure, we have a consistent system to measure it independent from the session.So in FP1, FP2, FP3, quali and race we measure all the tyres in the same way, we have consistent numbers in all the sessions, so we are 100 percent sure that only the blanket is heating the tyre and teams are quite happy because once they fit the tyre they are not allowed to bleed air but they have a reference pressure.I can give you a result in a couple of races when we have some numbers to evaluate but for me the ssystem is working so lets see what is going to happen.ddddddddddddTyre pressures have become a sensitive issue in F1, with many drivers saying Pirelli consistently set them too high for the circuits. Following Friday practice in Austria, Fernando Alonso complained that F1 is the the only category where you cannot setup your own car.But with some teams finding ways to lower their running pressures, Pirelli has had no choice but to go conservative across the board. If the new system ensures running pressures consistently remain within the limits Pirelli is targeting, then Isola said the tyre manufacturer would consider lowering the pressure prescriptions from the historic highs that have featured at rounds so far this year.Of course. The starting pressures are based on simulation or our analysis, but then on our analysis basically we consider a qualifying lap and a race lap, and you measure the stress on the tyre and the stress on the tyre is linked to the running pressure.That is something that at the moment we are not enforcing, because we are enforcing the starting pressure. So depending on the running
