DENVER -- The Rockies have reached a Minor League agreement with Jason Giambi, who has served as a pinch-hitter and backup to Todd Helton at first base with the team since late in the 2009 season. Giambi, whose deal is pending a physical, turned 40 on Jan. 8 and is a former American League Most Valuable Player (2000). He hit .244 with six home runs and 35 RBIs in 176 at-bats last season for the Rockies. Giambi was at his best with men on base (.291, five homers, 34 RBIs) and with runners in scoring position (.362, 28 RBIs). The Rockies were looking for a right-handed complement to Helton, who has battled back injuries in recent years, and signed Ty Wigginton to a two-year, $8 million contract. But the left-handed-hitting Giambi could serve as insurance against injuries.
