Tiger Woods began his final round at TPC Potomac six shots back of the leaders, but is making moves to close that gap on Sunday.

First up, an unlikely birdie from thick, native grass at the par-5 second:

"Anything on the green here would be really good."

And then came this 20-footer for birdie at the seventh:

What is better than one birdie in a row? Two, of course! He drains back-to-back birdies with this at the eighth:

When it was all said and done, it was a 4-under 66 for Woods on Sunday. Win No. 80 will have to wait.
