The Washington Nationals have suffered more than their share of injuries this spring. Michael Morse, Adam LaRoche and Rick Ankiel have all missed time. On Saturday, Bill Ladson summed up all the issues:

LaRoche continues to have a left foot problem and feels pain when he runs the bases. LaRoche hurt the foot while doing a baserunning drill last month.

Morse recently had an MRI exam, and it revealed that he still has a strained right lat muscle. Morse, who has played three exhibition games, can swing a bat, but he still can't throw a baseball. Ankiel continues to have left hamstring issues and has not played since March 9 against the Marlins.

Ladson's article indicated that all three would get "at-bats on the minor league field."

But that was then. This is now:

Michael Morse and Adam LaRoche are not expected to perform baseball activities for at least a week.#Nats #MLB

With that in mind, the Nats brought in someone for insurance:

I just learned that the #Nats have signed OF Xavier Nady to a Minor League deal. He is currently in Minor League camp. #MLB

Nady, who hasn't been anywhere close to his 25 HR, 97 RBI, .305/.357/.510 season in 2008 since he had Tommy John surgery the following year, hit .248/.287/.359 in part-time duty (82 games) for the Diamondbacks in 2011. He's not expected to make the Nats' Opening Day roster, according to Ladson:

#Nats OF Xavier Nady doesn't have any outs in his contract and will start the season with Triple A Syracuse.#MLB

The Nats should get Ankiel back on Tuesday, says Ladson. But clearly, they're worried about LaRoche and Morse, as the 2012 spring training injury parade continues.
