WIMBLEDON, London -- "Is that all you got?" Ivan Lendl joked after Andy Murray smashed a ball his way in practice on Tuesday morning.
There was the usual banter as the world No.2's coach kept the mood light during final preparations and then it was strictly business once Murray stepped out on Wimbledon's Centre Court against Liam Broady.
Murray showed Lendl exactly what's in his locker as they bid for a second title here together. He executed a clinical 6-2, 6-3, 6-4 win over his wild card opponent, in what was the first all-British meeting at a Grand Slam since 2006, and first at Wimbledon since 2001.
The Scot got almost everything right Tuesday -- apart from a slip up in his postmatch press conference after rain disrupted much of the day's play.
"I'm happy I got done in three sets. If that had gone to four, potentially I'd have to hang around and wait," he said. "Actually, I wouldn't. I had the roof. Wouldn't have to worry about that!"
Murray's timing on court was perfect, though: he managed to beat the bad weather by a matter of minutes, having got the job done in less than two hours. As soon as the players walked off, the covers came on and the roof moved into place.
Murray joked on social media that he 'got out of jail free' after his second five-setter in as many matches during the first week of the French Open last month.
His early exertions at Roland Garros certainly didn't help him the final against Novak Djokovic, and he looks determined to avoid a similar scenario here, should the anticipated rematch take place a week Sunday.
The Scot was presented with a good opportunity to find his feet against a lower-ranked opponent but didn't mess around.
Murray didn't drop serve once in 14 games, winning 88 percent of his first serve points. He looked aggressive from the baseline, hitting 31 winners and winning 18 of 19 points at the net too.
He also didn't allow Broady a single break point in the first two sets and there was only one blot on his copy book all afternoon; a loss in concentration coughed up two chances for the world No.235 at 3-2 in the third set but Murray held from 15-40 down.
"Any tournament it's important, when you have a chance to win a match quickly, to do it," Murray said. "It's not always that easy. Sometimes your opponents can play very well, and sometimes you're struggling a little bit.
"When you have the opportunity in matches to finish them, you have to try and be ruthless. The French Open was tough for me. I had a couple of long matches to start the tournament.
"I have also won the matches fairly quickly. I just need to try and understand why that's been the case in the past, and hopefully I can have another good start here."
Murray and Lendl are off to a hot start together after reuniting on the eve of Queen's. They claimed the title there -- a record fifth for Murray -- and have gone six matches unbeaten. If they add six more they will have another, more coveted crown.
Lendl's nickname is 'Old Stoneface', earned through his lack of visible emotion during a playing career that brought eight Grand Slam titles, but on the practice court he is all smiles.
"We both enjoy a little laughter here and there," the Czech told the BBC, and Murray has indeed seemed more relaxed since he has been back with the man who guided him to his two major titles and Olympic gold medal during their first spell together.
Lendl's competitive nature -- he was "not a happy person" after losing to Murray on the golf course on Monday -- also seems to be something they have in common.
Murray told ESPN before the match how having Lendl back as his coach gives him more confidence. The Czech-born American hasn't been trying to teach Murray technique, and sees himself more as a motivator and tactician.
Whatever he has been doing, it appears to be working.
