MLB: Philadelphia Phillies, Colorado Rockies may be in on Luis Castillo - ESPN
Buster Olney says the Rockies are one of a few National League teams that have interest in the recently-DFA'd Luis Castillo. I'm not sure how much of an upgrade Castillo would be over the combination of Jonathan Herrera/Jose Lopez, but it is worth noting that Castillo's career .368 OBP trumps all of them. However, he is coming off the worst season of his career, and unlike Herrera and Lopez, he is on the wrong side of 30. He also hasn't had an above-average defensive season (in terms of Total Zone Rating) since his days with the Florida Marlins - six years ago. It may be best for the Rockies to stay away from Castillo, and let the Phillies or Cubs have him.

Rockies’ Maine ‘too amped up’ in spring debut | All Things Rockies — Colorado Rockies news — Denver Post
John Maine struggled through three innings against the Reds yesterday, as he continues to regain his composure on the mound after missing a year a baseball. The important thing, however, is that his shoulder is holding up well. Maine likely isn't going to make it into the Rockies' rotation to start the year, but if he decides to accept an assignment to Colorado Springs, he could find himself with the big league club by mid-season (completely dependent on his AAA performance, of course).

Rogers gets chance to improve his bid for fifth starter - The Denver Post
Esmil Rogers, who probably has the inside track in the fifth starter race at this point, will pitch today against the Angels. Also included in Jim Armstrong's piece are notes on Huston Street and Jhoulys Chacin, who dominated their competition yesterday.

Rockies Recap: Reds 10, Rockies 3 | All Things Rockies — Colorado Rockies news — Denver Post
In another Armstrong recap, he informs us that the Rockies have reassigned Charlie Blackmon and Ben Paulsen to minor league camp. Blackmon (.314, HR, 6 RBI) and Paulsen (.458, HR, four triples) certainly made an impression on the Cactus League. We'll probably see both guys in Colorado Springs this season. Blackmon is a legitimate major league prospect; the jury's still out on Paulsen. Hernan Iribarren, Sean White, and Claudio Vargas were reassigned as well.

Spring training 2011: Brian Wilson of San Francisco Giants injures ribcage - ESPN
The Giants' closer may not be ready for the start of the season, but the team will know a little bit more tomorrow once he is re-evaluated. Either way, it's a sign that a little bit of the luck that helped carry the Giants to a World Series championship might be changing a bit this year - something that, while not easily predictable, always seems to happen. With that being said, losing someone out of the bullpen is easier to handle than missing a guy out of the starting lineup or rotation.
