NEW YORK As they took the field for their 16th road game in a19-game span Thursday afternoon, the weary Giants wanted nothing more than ninebrisk innings before a six-hour flight home. Instead, Jonathan Sanchez brought his high-wire act to themound. And it's wearing thin. For the second consecutive start, Sanchez walked six in fiveinnings. This time, the free passes stung him. Jose Reyes redeemedtwo of them on his triple in the second inning, Carlos Beltran hita two-run homer in the fifth and the Giants were denied a winning tripafter a 5-2 loss to the New York Mets at Citi Field.
