World No.16 Ireland had defeated No.10 India in the pool stage and both teams on Thursday approached the match at the Lee Valley Hockey and Tennis Centre with emphasis on defence.
After a lull first period, both teams intensified their attacks in the second quarter, with India using full-press to keep the pressure up. India remained effective yet calm in their attack, rotated the ball patiently to find the right opportunity in the circle but a real chance on goal continued to elude them.
For the Irish though, Anna O'Flannagan remained the cynosure of their attack when she cleverly positioned herself to find a deflection off a cross that sliced through their striking circle from the right. But India's goalkeeper Savita made a diving effort to deny Anna a goal.
With a little over 30 seconds remaining for the half-time, India's striker Rani Rampal made an aggressive dribble to enter the circle but a good tackle on Ireland's part ensured both teams went into the ten-minute break at a 0-0 deadlock.

The fourth and final quarter was tense with both teams upping the ante. India found a great opportunity to score when they won a crucial penalty corner in the 49th minute. Though Lilima Minz's injection lacked the pace, Rani picked up a powerful shot but only to send it straight to the Irish goalkeeper Ayeisha McFerran.
India lost the video referral with a little over five minutes to go for the final hooter as Vandana asked for a deliberate infringement by Irish defender.
India's chances were further dented when they were down to ten players with Udita getting a green card in the 57th minute.
With time racing away, Ireland took a final chance in their attack but the match when into a shootout during which Rani, Monika and Navjot Kaur flopped in India's first three attempts.
