Dan playing great. Been way more impressed than I expected with his serve (could do with making a few more first serves and two horrid DF's at 5-5 but his serve has quite a lot of depth and fizz on it and the second one has a lot of kick).
But it's taking the ball early and being constantly dynamic that's winning him points (and Kudla being a bit narked - he must know he had some excellent chances at 5-5- and really blew them).
