The World Baseball Classic, while successful, is viewed with white knuckles by many industry executives. There is concern about injuries and having a player miss nearly three weeks of spring training, potentially disrupting chemistry.

In that regard, the Rockies received good news Monday. It's growing increasingly unlikely that Rockies shortstop Troy Tulowitzki will participate because of the risk he poses for the WBC committee, which would need to insure the $140 million remaining on his contract.

Tulo, who was supposed to have a final workout to be added to Team USA's provisional roster Thursday, said Monday he didn't think the WBC was going to sign off. This doesn't mean his surgically repaired left groin isn't healthy, rather that the WBC would prefer not to take the financial risk on his contract. The committee faces a similar decision with Reds star Joey Votto, who is a candidate for the Canadian team.

Tulowitzki has been taking groundballs and hitting regularly in Las Vegas, where he recently worked out with Rockies infielder Josh Rutledge. Tulo witzki wanted to test his leg in the WBC, which offers a more competitive environment than spring training, but knew it might not happen given the red tape he has been cutting through over the last few weeks.

Facing the challenge of improving his defense and jumpstarting an embattled rotation, Rockies catcher Wilin Rosario has chosen to forgo a spot on the Dominican Republic roster.

"I won't be playing in the WBC this year," Rosario tweeted. "I will be working with the pitching staff, and we have a lot of work to do."

Adam Ottavino (Italy) and Jeff Francis (Canada) indicated last weekend that they won't be playing. Top Rockies prospect Nolan Arenado is listed on Puerto Rico's provisional roster, but he told The Denver Post on Monday that he's unlikely to participate. Arenado, 21, will compete for a roster spot in spring training at a crowded third-base position that includes Jordan Pacheco, Chris Nelson, D.J. LeMahieu and Ryan Wheeler, who was acquired from the Diamondbacks for reliever Matt Reynolds.
