Jordan Montgomery dazzles in debut for St. Louis Cardinals, blanks New York Yankees less than a week after being dealt 11:47 PM ET ESPN News Services ST. LOUIS -- Jordan Montgomery was open and honest with reporters when asked about his debut with the St. Louis Cardinals and how he needed to face his former team less than a week after being traded. "It's not exactly what you want to do for your first time being in a new organization," the former starter for the New York Yankees said on Friday. "But I'm a competitor." On Saturday, he showed it. Montgomery blanked his old teammates over five innings and Nolan Arenado drove in the lone run as the Cardinals handed the Yankees their season-high fourth straight loss, 1-0. Montgomery (4-3), who after the win said he had a cramp in his hamstring because of dehydration, was taken out after five innings for precautionary reasons. He gave up two hits and a walk with one strikeout, adding afterward that it's going to take him a bit to get used to the humidity in St. Louis. Combined, four Cardinals pitchers held the Yankees to just two hits -- singles in the first and third. Only two runners reached second base. Giovanny Gallegos pitched 1-2-3 ninth inning to earn his 11th save, striking out the final two hitters.

The Cardinals are 10-2 over their last 12 games at Busch Stadium, including seven straight wins. An announced crowd of 48,581 watched the home team's victory, the largest crowd ever in Busch Stadium history, including regular season and postseason games along with the 2009 All-Star game.
