DENVER -- The Rockies are making a push for veteran infielder Orlando Cabrera, according to Major League sources.

The Rockies have an open roster spot, and general manager Dan O'Dowd has been monitoring the market, with veterans such as Cabrera, former Orioles All-Star Melvin Mora and Gold Glove Award winner Orlando Hudson still available.

It appears that it is down to the Rockies, Reds and Nationals, according to one of the sources.

Rockies manager Jim Tracy was the Expos' bench coach and Rockies assistant general manager Bill Geivett was a key figure in player development when Cabrera came up with Montreal in the late 1990s.

Cabrera, 35, split last season with the Athletics and Twins and hit .284 with nine home runs and 77 RBIs. In his career, Cabrera is a .275 hitter with 114 home runs and 761 RBIs.

The right-handed-hitting Cabrera has spent most of his career at shortstop, but, with Troy Tulowitzki entrenched at the position, Cabrera would only be seen as insurance there. He also has experience at second base, where the Rockies have Clint Barmes. Cabrera could push Barmes for starts and see action at third, where the Rockies have left-handed-hitting Ian Stewart.
