Quick Hits: Orioles, Cardinals, De La Rosa, Matsuzaka

Links for Tuesday night, as Tigers catcher Alex Avila enjoys his third career two-homer game…

• Orioles president of baseball operations Andy MacPhail told MLB.com’s Brittany Ghiroli that he will continue considering internal and external replacements for Brian Roberts, who won't return before the end of May (Twitter link). 
• Jeff Gordon of the St. Louis Post-Dispatch explains that the Cardinals demoted Mitchell Boggs in spite of his strong 2011 numbers because they can stretch him out at Triple-A. The Cards could have near-term needs for starters or middle relievers. 
• On a related note, GM John Mozeliak told Tom Krasovic of MLB.com that he may explore trades for relievers at the deadline. However, Mozeliak says it’s still too early to predict with certainty that the bullpen will be the Cardinals’ biggest need this summer.
• Rockies left-hander Jorge de la Rosa has a complete tear of the ulnar collateral ligament in his left elbow, the team announced (on Twitter). Tommy John surgery appears to be a likely option for de la Rosa.
• Troy Renck of the Denver Post suggests we should keep Kevin Slowey in mind as a possible target for the Rockies should they look outside of the organization for rotation depth (Twitter link).
• Yahoo's Jeff Passan calls Daisuke Matsuzaka a "$103MM migraine" and reports that the right-hander has ignored what the Red Sox have wanted him to do since signing with Boston. Matsuzaka, who has a sprained UCL, might never pitch for the Red Sox again if he needs Tommy John surgery, according to Passan.
• Jim Bowden of ESPN.com previews his top five potential sellers at this year's trade deadline: the Mets, Astros, Twins, Cubs and Padres.
