NL West Notes: Rizzo, De La Rosa, D’Backs

Giants catcher Buster Posey appeared to suffer a serious leg injury while blocking the plate in extra innings last night. Posey's agent, Jeff Berry, says he's going to call Joe Torre about changing rules for plays at the plate to make collisions safer for catchers, according to ESPN.com's Buster Olney. "It's brutal," Berry said. "It's borderline shocking. It just stinks for baseball." Here are some other notes from the NL West:

• Padres GM Jed Hoyer told Bill Center of of the San Diego Union-Tribune that top first base prospect Anthony Rizzo is "not yet" ready for the Major Leagues. The Padres want Rizzo to stay in the Majors once he arrives, so "the timing and situation has to be right."
• Rockies GM Dan O'Dowd told Dave Krieger of the Denver Post that he has the financial freedom to make a trade. "I have some flexibility that we saved for opportunities that may come up," O'Dowd said. "It would be hard to do multiple things, so we're probably going to have to prioritize what that is if something should come available." Though the Rockies aren't about to make a sudden move, they'll keep talking to teams about possible deals.
• The Rockies will call on internal options to replace Jorge de la Rosa, who will miss the rest of the season with Tommy John surgery, according to Troy Renck of the Denver Post. Rockies owner Dick Monfort says the team didn't have insurance on the left-hander's contract.
• The D'Backs continue to eye other teams' arms as they look to bolster their Triple-A pitching depth, according to Nick Piecoro of the Arizona Republic.
