Barty will rue her missed opportunities in the opening set - after trading breaks with Goerges in a tight set, she let four set points slip by across three games and another three in the tiebreak.
Her conqueror by 6-2, 6-4 was Barbora Strycova, a tenacious Czech with a good record at this tournament, but not yet a Grand Slam contender and languishing several places outside the world top 20.
"I'm a fighter and I like to fight, on and off the court", said Strycova. "You have to play tricky in these conditions, and I did that, although I admit in that last game I was very nervous". This time, she has had only two.
"Every time I play her, I have to play my best tennis, and it happens", Strycova said. I just want to learn and next time I face her, I want to win. "I enjoy playing on grass here". "I'm going to practice more to get ready for Wimbledon (in 11 days)". Gavrilova raised her level and she played on the level terms with Petra in the first five games, creating a break point at 2-2 that Kvitova successfully defended to stay on the positive side of the scoreboard.
The young Australian won last week's Nature Valley Open title in Nottingham but ran out of steam against the able German and will now continue her Wimbledon preparations at next week's Nature Valley International in Eastbourne.
Although Muguruza lost in Birmingham a year ago too, she played four useful warm-up matches against two this time. It's probably not really her favourite surface. "But my serve has always been a weapon, and I've been working a lot on it". When it was deuce, I played the second serve, she went for it, but she missed it.
