NEW YORK — Slumping center fielder Melky Cabrera was demoted to the minors Friday, the biggest move in a mini shakeup by the struggling New York Yankees as they tried to regroup for a playoff push.

The Yankees also designated backup first baseman Richie Sexson for assignment and placed pitcher Dan Giese on the disabled list. The club brought up three players from Triple-A Scranton/Wilkes-Barre: outfielder Brett Gardner, infielder Cody Ransom and reliever Chris Britton.

"We're doing some tweaking," general manager Brian Cashman said. "These are baseball decisions. The shakeup's got to come from the guys that are expected to perform. Melky Cabrera batting ninth in our lineup is not supposed to be a difference-maker in this club either way. He was supposed to be able to slide right in while everybody else did their job.

BASEBALL SOURCE SAYS YANKS FIRE 2 SCOUTS: The New York Yankees have fired two scouts under investigation in a probe of possible skimming from contracts with Latin American players, The Associated Press has learned. The Yankees terminated the contracts of Carlos Rios, their director of Latin American scouting, and Ramon Valdivia, their Dominican Republic scouting director, a baseball official said Friday. The official spoke on condition of anonymity because no announcement had been made.

The two, who had been on leave, were terminated Thursday, the official said.

They were accused of skimming six figures from the deals, a second baseball official said, also speaking on condition of anonymity because no announcements had been made.

Yankees general manager Brian Cashman declined comment.

Major League Baseball has been investigating alleged skimming involving Latin American operations for months.
