I did not think hairston was a major move myself:
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."
