In the second set, Halep took her foot off the gas, allowing Tomljanovic to find her rhythm.
After dropping the second set, Halep went back to her brand of tennis, aggressively counterpunching from the baseline, building a cushy lead to close out the match.
The level was great, and actually her level in the second set was really high, Halep said.
Halep is aiming to be the first woman to defend a Grand Slam title since 23-time major champion Serena Williams defended her Wimbledon trophy in 2016.
