Red Sox Notes: Felix Doubront, Ryan Lavarnway, Jon Lester, Ryan Sweeney

Here's the latest from the Boston Red Sox, where Felix Doubront is looking to make the team on the heels of a landing adjustment:

• Felix Doubront is facing a make-or-break spring, according to Tim Britton of The Providence Journal. Doubront is out of options and could be exposed to waivers or trade if he doesn't make the team.
• Boston Pitching Coach Bob McClure might have found a key adjustment in Doubront's delivery, focusing on landing the lefty on his toes, rather than his heel, reports Rob Bradford of WEEI.
• Over the Monster asks which of three players (Lavarnway, Iglesias, or Doubront) is most likely to make the biggest impact on Boston's 2012 season.
• Jon Lester beats up on college kids and Michael Silverman calls it a foundation.
• Scott Lauber of the Boston Herald reports that David Ortiz might see a little time at first base with Adrian Gonzalez in the outfield when it comes to interleague play.
• Rob Bradford of WEEI asks whether the Red Sox can develop Ryan Sweeney's power, which Manager Bobby Valentine says is a mechanics issues and a "correctable problem."
