DENVER -- The Rockies have reached a Minor League agreement with second baseman Kazuo Matsui, who will join Triple-A Colorado Springs provided he passes a physical on Tuesday, Major League sources said Monday.

The Rockies have yet to make an official announcement.

Matsui, 35, signed with the Astros after hitting .300 in a Rockies uniform in 2006-07. He put up strong numbers in an injury-shortened 2008 with the Astros, but declined last season (.250 BA, 9 HR, 46 RBIs) and hit .141 in 27 games this season before being released last Wednesday.

Matsui cleared waivers on Monday.

If Matsui passes his physical -- back injuries have bothered him for years -- he will go to the Sky Sox to stay sharp and provide infield insurance for the Rockies.
