SAN DIEGO -- It's been a busy month on the Minor League side for the Padres, as they extended their player development contracts with four of their affiliates, the latest being the Triple-A Portland Beavers.

The Padres announced Thursday that they have extended their PDA with the Beavers through the 2010 season.

"The Padres are excited about our continued agreement with the Portland Beavers," San Diego vice president of scouting and player development Grady Fuson said. "With Merritt Paulson and his staff, we know we have a great partner in the Portland franchise. The player and staff experience in Portland is a vital part of the growth process to the Major Leagues, and is a perfect fit for the Padres organization."

The Beavers have been the Padres Triple-A affiliate since 2001, compiling a 561-584 (.490) record over parts of eight seasons with a playoff appearance in 2004. Portland was 69-70 (.496) this season entering action Friday, in fourth place in the Pacific Coast League's North Division. The Beavers downtown Portland home, PGE Park, will host the 2009 Cricket Wireless Triple-A All-Star Game.

"We look forward to continuing our association with Merritt Paulson and the entire Portland Beavers organization for the next two years," Padres general manager Kevin Towers said. "As the final stepping stone before they enter into the Major Leagues, several of our players have reaped the benefits of the great facility and staff in Portland."
