The Colorado Rockies have finalized a one-year, $1.75-million contract to bring Jason Giambi back to Denver to back up Todd Helton at first base.

Colorado also agreed Thursday to minor league contracts with left-hander Jimmy Gobble and right-hander Justin Speier.

Giambi hit .292 with two homers and 11 RBIs in 19 games for the Rockies last September. He had two game-winning hits and helped Colorado win the NL wild-card.

The 39-year-old is a 15-year major league veteran originally drafted by Oakland in 1992. He was voted AL MVP in 2000 while with the Athletics, then signed a $120 million, seven-year contract with the New York Yankees.

He returned to Oakland last season, getting a one-year, $5.25-million deal. The Athletics released him on Aug. 7 and he signed with the Rockies 2½ weeks later.
