I have patches of an unidentified grass growing in my lawn. The grass is a lighter green than my other grass and grows twice as fast. I have been pulling it out by hand and it seems to come out easily. I can't tell if there are leaders buried close to the lawn surface but it seems a possibility. Can you identify this grass and tell me how to get rid of it without damaging the rest of my lawn?

From your description, it sounds like it could be roughstalk bluegrass (Poa trivialis).
This is a relatively new lawn weed. It is a perennial grass weed that is difficult to control. Even golf course superintendents struggle with it on golf courses. Please see the following information on our website, http://extension.umd.edu/hgic/roughstalk-bluegrass
