Griffin Whitman, a 10-year-old Red Sox fan from Swampscott, was excited to attend his first Yankees vs. Red Sox game Friday night. The young autograph -collector was even more thrilled to score Yankees outfielder Shelley Duncan’s signature before the game. That is, until Griffin read the message from the 27-year-old rookie: “Red Sox suck! Shelley Duncan.”

"It was cool to get his autgraph," said Griffin.  "It didn’t make me feel happy that he wrote that."

Griffin’s mother, Karen, blasted the Yankees slugger’s bad manners.

“This is someone who wears the Yankee uniform and is on the payroll and should be setting an example for 10-year-olds,” she said.

Duncan, son of St. Louis Cardinals pitching coach Dave Duncan, has become a fan favorite in the Bronx for hitting mammoth home runs since he was called up from the minors in July.

Yesterday afternoon, a Yankee spokesman declined to comment until he got a chance to speak to Duncan.
