Champions Rangers went one better as they beat promoted Glasgow Girls 14-0 on a day of big wins for the western big three, but it was a great day for Jambos.
Eva Olid has invested heavily in her squad and the changes appear to be paying immediate dividends, although Hearts had to work for their three points after trailing at half-time.
Cara Henderson gave the Jags the lead in first-half stoppage time when she ran on a through ball to finish, but Timms’ second-half hat-trick turned the game around.
She could have scored late in the first half when she deflected an Ocean Rolandsen cross from the post, but didn’t have to wait long to score her first goals.
Timms’ first goal was a calm finish on the post five minutes into the second half after running on a ball from Emma Brownlie. She added a second in a minute. The England striker, signed from Lewes, cut the left channel and curled a nice shot into the corner.
Thistle then had a chance to equalize when Charlotte Parker-Smith brought Henderson down, but the goalkeeper redeemed herself with a big save to her left before Hearts raced up the park, earning a penalty of their own as the New Zealand international Katie Rood had stumbled into the box. Timms sent Khym Ramsay the wrong way to seal his hat-trick.
Hearts assistant manager Sean Burt explained what made the difference after halftime.
“We told the girls to go back out there and play their game,” he said, when asked how the team turned things around.
“The first half went the way Partick Thistle wanted it to, but we knew we could impose more on the game.
“In the second half we emphasized again that we want to play our style of football and the girls did that brilliantly for us. I’m delighted for Georgia Timms. She worked very hard with us in pre-season and you saw today how good she is going to be for us this season.
On a miserable day for Hibs, defender Siobhan Hunter was sent off as Celtic put Dean Gibson’s side to the sword.
