PHOENIX -- The Rockies placed veteran Jason Giambi on the 15-day disabled list Tuesday with viral syndrome, retroactive to July 21.
The Rockies replaced Giambi, 41, in the roster with left-handed pitcher Edwar Cabrera, who started Tuesday night's game against the D-backs.
"He's just experienced body weakness and things like that," Rockies manager Jim Tracy said of Giambi.
Giambi, who said he has not felt well for three weeks, is hitting .241 with four doubles, one home run, eight RBIs and seven runs in 47 games for the Rockies this year. In 217 games with the Rockies since 2009, he is hitting .251 with 20 doubles, 22 home runs and 86 RBIs.
Giambi is in the final year of a two-year deal he signed with the Rockies before the 2011 season.
