Here we are, three days into the Winter Meetings, and the biggest thing to happen to the Chicago Cubs so far is a trade involving Omar Infante.

True, there's time: we have a lot of off-season yet to play, and the Cubs could still make a signficant move before Team Hendry leaves Nashville. I don't have nearly the browsing skills to keep up with all of the Cub-related rumors circulating, but the most recent one involves the possible acquisition of Orioles second baseman Brian Roberts.

As covered in the Baltimore Sun...

Although no specifics have been revealed, one baseball source said the Cubs have put a "significant" offer on the table that would include a starting pitcher for Roberts, the Orioles' lone All-Star in 2007.

One player in the proposal is believed to be right-handed pitcher Sean Gallagher, who entered last season as the Cubs' fifth-ranked prospect, according to Baseball America. Gallagher, 21, pitched primarily in Double-A during the 2007 season, going 7-2 with a 3.39 ERA in 11 starts. He made eight appearances in relief for the Cubs, allowing 14 earned runs in 14 innings.

It's likely the second player in the deal would be a position player, although the Cubs' top prospect, outfielder Felix Pie, is not being offered, according to a team source. One possibility is outfielder Matt Murton, 26, who hit .281 last year with eight home runs and 22 RBIs in 235 at-bats.
