Ireland beat Mexico convincingly in their latest match at the Olympic qualifying tournament in Belgium to make it three wins out of three.
The Irish girls found it difficult to break down the Mexican defence in a scoreless first half.
After the break, goals by Audrey O'Flynn (2), Emma Smyth (2) and Cliodhna Sargent ensured victory.
The match saw Nicola Symmons become the most capped Irish player of all time as she played for the 172nd time.
Ireland now lie top of their pool after three games, but play the top seeds Spain on Thursday.
The first half was totally dominated by Ireland but they were denied several times by the Mexican goalkeeper.
Aine Connery went close at the start of the second period, before O'Flynn scored her fourth goal of the tournament.
Correa got her marching orders when she received a 10-minute yellow card for a heavy challenge on Emma Clarke.
In the remaining 11 minutes Ireland scored four goals, the first of them in the 60th minute when Nici Daly earned a free just outside the circle and after a goalmouth scramble Emma Smyth reversed into the net from six yards to give Ireland breathing space and a two-goal lead.
In the 64th minute O'Flynn made it 3-0 when she buried the rebound after her initial drag was saved.
Smyth got her second from a second phase penalty corner two minutes later and in the final minute of the game Cliodhna Sargent made it 5-0 from open play.
"It was generally a frustrating match for us we found it hard to create goal scoring chances in the first half but we were more fluid and clinical in the second half," said Irish coach Gene Muller.
"There are now only three teams who can win the tournament and our next two games against Spain are critically important."
