It was so good to see someone like Jack Draper step up and win it with good tennis. Look at the emotion he's showing now. He grabbed it in the tie break and what a moment for this young man.

What a Davis Cup debut for 21-year-old Jack Draper.
He comes from a set down to get the victory. He lost the opening set on a tie-break, won the second and was a break down in the third, with Kokkinakis serving for the match.
But Draper hung on in there and then recovered from 4-2 down in the third set tie-break, winning five points in a row to get Great Britain off to a winning start.
What a match!
So close to a double fault, but the ball just creeps over the net on the second serve from Kokkinakis. Still 6-4 Draper.
Kokkinakis goes long. Draper with two match points, 6-4 Draper.

Draper loves it. Loves it!
He picks out someone in the crowd, thanking them for their support and kissing his badge towards them.
More, he says. He wants more noise!
Draper gets his third point in a row, sliding into the net to thump away a volley. From 4-2 down to 5-4 up.
An ace from Draper and it's 4-4. Great match to start us off with another singles and then a doubles match still to come.

Whatever happens, it's a debut to remember for Jack Draper. What a dramatic match in a fantastic atmosphere.
Kokkinakis, going for the cross-court winner, puts too much on it and it just misses the angle, 2-1 Draper.
Draper returns long from the Kokkinakis serve, 1-1.
A great dig out from out wide from Draper, Kokkinakis sends a loose one into the stands, 1-0 Draper.

Superb serving from Thanasi Kokkinakis under great pressure. First superb first serves haul himself out of danger at 15-30 to hold and force a deciding set tie-break.
Kokkinakis pulls a two-handed backhand wide left, 15-30. Draper two shots away.
Kokkinakis is looking a bit nervous, with too much on the forehand and he goes long, 0-15 and Draper three points from the finish line.

There is so much tension in this opening singles match.

With that extraordinary shot, Jack Draper has the Manchester Arena erupting like the Stretford End after a last-minute winner.
He looked beaten by the lob.
Somehow he not only reached it, but whipped away the winner.
Kokkinakis, like everyone else in here, did not expect to see that.
