Andy Pettitte gave up three hits in seven strong innings and Jorge Posada hit a two-run single, carrying the New York Yankees over the Royals 4-1 Friday in the opener of Kansas City’s renovated Kauffman Stadium.

Pettitte (1-0) struck out six and walked one while allowing one run against a team he has long dominated. The left-hander beat the Royals for the 13th time in 16 career decisions and improved to 8-0 against Kansas City in his last 12 starts.

Sidney Ponson (0-1), who made 15 starts for New York last year, gave up four runs and six hits in his Royals’ debut.
