GAME, SET AND MATCH! - EDMUND 6-3 6-3 KUKUSHKIN. What a performance! Much has been made of Edmund's problematic 2019, but he's stepped up to the mark in Andy Murray's absence here.

The British No.1 faces Alexander Bublik shortly.

EDMUND 6-3 5-3 KUKUSHKIN. No danger for Kyle. His serving has been splendid throughout this clash. He helps himself to a feast of cheap points to hold to 15. He's one game away from victory. Kukushkin has the demeanour of man who knows he has been second best in most departments today.

EDMUND 6-3 4-3 KUKUSHKIN. Mikhail stays in touch as he races through four points in a row after Edmund's backhand down the line had given him very brief hope of the double break.

BREAK! - EDMUND 6-3 3-2 KUKUSHKIN. Edmund comes under some real scrutiny on serve so far this set, but springs forward to seize a significant break!

A jaw-dropping rally follows with Kukushkin blinking first. GB are a set and a break to the good.

EDMUND 6-3 2-2 KUKUSHKIN. More adversity to overcome on serve for Edmund, but he rises to the task in-hand once more. At 15-30 he challenges a serve called out and gets his reward with an ace. A lung-busting rally ensues with the Brit showing his growing confidence with a sizzling backhand winner down the line to set himself up for another fine hold.

EDMUND 6-3 1-1 KUKUSHKIN. Early danger for Edmund as Kukushkin corks a return winner down the line to snare two break points. A timely sixth ace of the encounter staves off one before some controlled baseline rallying off the backhand lures the error out of the Kazakh. Edmund then gets the job done from deuce, thumping down ace No.7.

EDMUND 6-3 0-1 KUKUSHKIN. That's just the start Kukushkin would have wanted to kick-start his hopes here. The world No.67 slaps an ace down the middle T to claim a hold to 15.

BREAK! - EDMUND 4-2 KUKUSHKIN. Wowzer - that Edmund forehand. The Brit crunches a rasping return winner and then sets up double break point with another thunderous drive off his favoured flank. Kukushkin is relieved to save the first but then conjures up a belting forehand of his own to reach the sanctuary of deuce. Edmund looks frustrated but keeps the pressure on. A third opportunity goes begging but when he finds the heat on his forehand on a fourth, it's just too good. GB have the breakthrough in this opening set!

EDMUND 3-2 KUKUSHKIN. Kyle keeps his nose in front with a confident hold to 15. The serve is firing and the forehand continues to hit its mark. Good signs so far for GB.

EDMUND 2-2 KUKUSHKIN. Frustration for GB. Edmund blows a backhand return long from the ad court as Kukushkin finds some big serves at deuce. The Brit had won a couple of tasty baseline battles to make it interesting but couldn't quite create the opportunity for the first break point of the match.
