A very rocky season in Colorado

This is rapidly turning into a terrible season for the Colorado Rockies.

Their pitching staff needs a lot more than a humidor, as their rotation is turning Coors Field into the launching pad it used to be in the 1990s. They've been so bad that manager Jim Tracy will experiment with a four-man rotation with a 75-pitch limit for each one, which certainly is going against the grain. Talk about an overworked bullpen -- the Rockies' bullpen arms are going to be very weary by August.

And now comes a dagger blow -- Troy Tulowitzki is injured again.

The shortstop will be out for a couple of months, diagnosed with a rare injury known as Hockie Goalie/Baseball Pitcher syndrome, with tears in the groin area that require surgery. (Ouch.)

With Tulowitzki out, the only good thing going in Colorado is outfielder Carlos Gonzalez, who is deserving of being the Rockies' (only) all-star.

"Like any club we are built around our best players. Even if we were having an average year rather than bad year, losing him would be problematic," Rockies GM Dan O'Dowd said to the Denver Post.

Expect Jeremy Guthrie -- demoted to the bullpen in the rotation move -- to be dealt very soon. And if a team wants to make a blockbuster offer for Gonzalez, O'Dowd might listen. Remember, they traded ace Ubaldo Jimenez to the Indians last summer.
