Ken Rosenthal of FOXSports says the Colorado Rockies may not be done finalizing their roster for a run at the playoffs. He says the team is looking at Seattle Mariners infielder Jose Lopez. The Rockies placed third baseman Ian Stewart on the 15-day disabled list with a strained right oblique muscle and are in need of infield depth.

A source close to Rosenthal said he doubts the Rockies will actually land an infielder whether it is Lopez or another player.

The Philadelphia Phillies were looking “hard” at Lopez in mid-July, but ultimately passed on him.

Lopez, 26, is hitting .241/.273/.333 with 7 home runs and 48 RBIs. He will be a free agent after the season. There is a $4.5 million mutual option for Lopez in 2011.
