NL East Links: Howard, Rizzo, Hairston, McCann

Ryan Howard will be out of action for six-to-eight weeks following surgery to repain a torn medial meniscus in his left knee.  While Howard wasn't going to be a trade candidate at the deadline (no team would touch that contract), it's possible his absence might convince the Phillies to throw in the towel on the 2013 season and become full-fledged sellers this month.  Here's the latest from around the NL East…

• Nationals GM Mike Rizzo discussed his team's acquisition of Scott Hairston with reporters (including MASNsports.com's Dan Kolko) today.  Hairston was the Nats' top target for right-handed bench help and the club had been negotiating with the Cubs for a couple of weeks, with an eye towards getting the deal finalized before the Nationals' current series with the Phillies.  Rizzo liked that Hairston was contracted through 2014 so he can be an asset to Washington next season as well.
• Rizzo also noted that the Nats could make another move before the trade deadline but it won't be anything major.  "You never stop trying to improve your club, but with that said, we feel like we like the club that we have and we're certainly playing better and we'll see where it takes us from here," Rizzo said. "I don't see any type of big splashy moves that are remaining."
• Dave Cameron of Fangraphs likes the Hairston trade, noting that it's the kind of shrewd low-cost move that can pay dividends if Washington ends up in the postseason.
• Thomas Boswell of the Washington Post opines that a trade package of Danny Espinosa, Ross Detwiler, Tyler Moore and Lucas Giolito might be enough for the Nationals to obtain David Price from the Rays.  While that's not a bad offer, I think the Rays could score a lot more elite talent if they started shopping their ace lefty.
• Braves catcher Brian McCann finally seems to be fully healthy and has been red-hot over the last two weeks, leading David O'Brien of the Atlanta Journal-Constitution to predict that if McCann keeps it up, he'll score a free agent contact close to Yadier Molina's five-year, $75MM deal with the Cardinals.  O'Brien notes that this deal will come from an AL team that will eventually transition McCann to a DH role, which is why I'd argue that McCann's eventual contract will fall at least $10-$15MM short of Molina's deal.  McCann's bat doesn't carry a $15MM average annual value if it's not coming from the catcher position, plus Molina brought elite defense and a less-checkered injury history into his new contract.
• Zack Wheeler is set to face the Giants on Wednesday, almost two years after he was dealt from San Francisco to the Mets in exchange for Carlos Beltran.  ESPN New York's Adam Rubin talks to Wheeler and Giants manager Bruce Bochy about the trade, and Bochy has no regrets since his club was gunning for another World Series title.
• The Rangers would love to acquire Cliff Lee from the Phillies, CBS Sports' Danny Knobler writes, "but at this point the Phillies seem to have most people in baseball convinced that they won't trade Lee (or maybe anyone else)."
