Captain Katie Brennan (one goal, 18 disposals) showed her class to pile another goal on the Giants, increasing the margin to eight points by half-time.
Greiser looked sure to dribble the Sherrin through the goal square but a flying Grace Hill denied her a second major in the third stanza.
The ever-prolific Alyce Parker (two goals, 21 disposals, six clearances) and rugby sevens Olympic gold medallist Chloe Dalton put ball to boot to keep the Giants within three points. The orange tsunami threatened to sweep up the Tigers when Parker grabbed her second backed up by a goal from Haneen Zreika (one goal, 13 disposals).
But a tremendous effort from Monique Conti (one goal, 22 disposals, seven clearances) and Emelia Yassir (two goals, 10 disposals, two clearances) reclaimed the lead for the Tigers.
With pressure boiling from the Giants, Brennan and Greiser were inaccurate in front of goal. The Giants began to falter with fatigue setting in, allowing Courtney Jones to kick truly and score the first goal of the last term.
A major to Sarah D’Arcy sealed the win for the Tigers, while Parker hobbled off the field with a knee injury. AAP
Garner stars as slow-starting Roos beat Geelong in AFLW
Jasmine Garner produced a standout display as North Melbourne overcame a rare poor start to post a nine-point AFLW win over Geelong at GMHBA Stadium on Friday night.
The Kangaroos were held goalless in the first half for just the second time in their history, but they stormed home with four unanswered goals in the second half to post a 4.7 (31) to 3.4 (22) win.
Garner was influential in the win, tallying 32 disposals, 12 clearances, 11 tackles, 600 metres gained and a 50-metre goal on the run.
North ruck Emma King was a rock with seven marks to go with 25 hitouts, while forward Bella Eddey kicked two vital goals.
Kangaroos defender Jasmine Ferguson played an excellent shutdown role on star Geelong forward Chloe Scheer, who managed just 0.1 from three disposals. It came a week after Scheer booted five goals in a thumping win over Sydney.
Georgie Prespakis (27 disposals, one goal) battled hard for the Cats, but North Melbourne controlled the midfield battle after half-time to secure their third straight win to start the season.
The Cats, who are now 0-6 in head-to-head battles against North Melbourne, are 2-1 for the season.
Geelong’s Julia Crockett-Grills could be in trouble for a dump tackle on Mia King.
King was assessed on the sidelines for concussion, but was cleared to return.
