Corbin deal won’t impact Nats’ pursuit of Harper

The Nationals made it clear from the start of the offseason that they did not intend to wait around while Bryce Harper made his decision in free agency. On Tuesday, they crossed another major item from their own to-do list when they agreed to a six-year, $140 million deal with free-agent left-hander Patrick Corbin, the top starting pitcher on the market, sources confirmed to MLB.com.
