World number five Roger Federer delivered a tennis masterclass to beat rising star Alexander Zverev 6-1, 6-3 and clinch a record ninth Halle Open title on Sunday as he lay down a marker in the lead-up to Wimbledon.
The 18-times Grand Slam champion, who skipped the claycourt season to prepare for grass after winning the Australian Open and titles in Indian Wells and Miami, is in ominous form and won in Halle without dropping a single set all week.
"It has been a difficult year with a lot of practice, training and rehab so I am very happy to be back on the court," Federer said.
"I do not know if I will ever be going to win this tournament again so I will enjoy this one," said the Swiss, who has won eight Wimbledon titles.
The 35-year-old, defeated in his first comeback match in Stuttgart last week, took control from the start with an early break and kept world number 12 Zverev on his toes.
He earned a second break point with some deft volleying, which he pounced on to race through the first set in 24 minutes.
Zverev, who beat the Swiss in last year's semi-final and has already won three titles this year, had a chance to break at the start of the second set.
But he simply could not discover a chink in Federer's armour, even as he attempted to mix up his game by forcing the Swiss to come to the net more often.
A superb dropshot put Federer 5-2 ahead and sealed Zverev's fate before he won the match on his first match point with a crosscourt volley.
In doing so, he became the first player to beat both Zverev brothers at the same event, having defeated older sibling Mischa in the round of 16.
Lopez beats Cilic in nail-biting Queen's Club final
Spanish veteran Feliciano Lopez claimed the biggest title of his long career when he battled back to beat Marin Cilic 4-6, 7-6(2), 7-6(8) in a nerve-wracking final of the Aegon Championships at Queen's Club on Sunday.
The 35-year-old, who suffered a heartbreaking defeat in the 2014 final when he held a match point against Bulgarian Grigor Dimitrov, this time saved one in a tense tiebreak shootout before toppling the Croat.
Fourth seed Cilic also saved two match points, but at the third time of asking crowd favourite Lopez could finally celebrate a sixth career title after Cilic pulled a forehand into the tramlines.
"I can't believe that I finally won it, I've been waiting for 15 or 16 years to hold this trophy," an emotional Lopez, three times a Wimbledon quarter-finalist, said on court.
"I thought that at the end of the tiebreak after losing match points I wouldn't make it but I managed to do it.
"It was tough to put that (match point in 2014) out of my mind so it was difficult to handle my nerves but I managed it."
Lopez, yet another male player who appears to be getting better with age, is the oldest winner of the prestigious Queen's Club championship in the professional era.
He did it by defeating Stan Wawrinka, Tomas Berdych, Grigor Dimitrov and Cilic -- ranked three, 14, 11 and seven in the world rankings.
"It's the best week of my career, which is crazy when you're 35," said Lopez, who joins a celebrated list of former champions including the likes of John McEnroe, Pete Sampras, Boris Becker, Andy Murray and fellow Spaniard Rafael Nadal.
The match was decided in an epic tiebreak with both players showing remarkable grasscourt skills.
Cilic brought up match point with an ace but Lopez saved it when he cut off the Croat's attempted pass with a stretching volley. Lopez then had a match point only for Cilic to snuff it out with his 22nd ace of the match.
Lopez performed miracles to scramble a point at 7-7 and serve for the match but Cilic responded with a nerveless volley after an exchange of blows from the baseline.
A 19th ace for Lopez brought up another match point and this time Cilic could not reply.
