Colorado Rockies' ace Ubaldo Jimenez is on the trade market, and it appears that division rivals Boston Red Sox and New York Yankees are in the hunt for the pitcher.

According to SI.com, the Red Sox are "aggressively pursuing" the right hander, with the Yankees "lurking."

Other teams that are "interested" include the Cleveland Indians, Cincinnati Reds, and Toronto Blue Jays.

The availability of Jimenez is surprising, considering the stellar start of the year that he had last season for the Rockies. In 2010, Jimenez pitched a no-hitter in April and started for the All-Star game.

However, his performance tailed off in the second half of last season. This season, Jimenez is 6-9 with a 4.20 ERA and he just hasn't been the same pitcher he was during the first part of last season.

Still, Jimenez is young at 27 years of age, and has a promising career ahead of him.

The Rockies may be trying to rebuild after a disappointing season last year and being 12 games out in the NL West this year.

Both the Red Sox and Yankees are having great years, with Boston leading the Yankees by 2.5 games in the AL East, but the Yankees leading the AL Wild Card standings.

If Jimenez can put it together and return to the form he had in the first half of 2010, then he would be a major weapon for either team in the playoffs.
