It should be 4-2 as Hansberry's corner finds Jarrett free at the back stick, but she can't steer the ball into the net.
Substitute Iina Salmi strikes on goal from long range and it's not far off-target.
Kelly Zeeman is lucky not to see a second yellow for clattering Emma Hansberry 35 yards out. Jarrett lines up the free kick and strikes powerfully at goal, but it's straight into the arms of Ubachs.
Liza van der Most scores for Ajax Women. A fluke from Liza van der Most, as her cross sails over Ciamh Dollard into the net.
Verhoeve steps in off the right and has a go from distance with her left foot, but it's always rising and veering wide.
Lois Oudemast scores for Ajax Women. Wexford really started to tire now and Verhoeve picks out the captain Lois Oudermast in the six-yard box, and she has time to set herself before rolling the ball in the corner.
So close to a third for Ajax! Wexford only clear the ball as far as the edge of the box and it's a fantastic volley from Verhoeve that cracks the underside of the bar and, mercifully, bounces clear.
Hansberry has a chance to put in another good delivery with a free kick centrally, about 40 yards out, but she overhits this one.
Another inviting diagonal cross from Verhoeve just evades Jansen and is well-claimed on the bounce by Dollard.
Ajax are playing with a bit more freedom now and finding space around the Wexford box. Jansen, who barely had a sniff in the first half, is involved in everything and she works space for a shot that sails over the bar.
Half chance for Munsterman as the ball breaks to her on the edge of the box, but she slices her volley wide. Lauren Dwyer hurt herself in the 50/50 that led to it as she seemed to be caught by Lois Oudemast.
Ellen Jansen scores for Ajax Women. The turnaround is complete as Soraya Verhoeve's diagonal cross is glanced into the corner of the net by Ellen Jansen.
Another Hansberry delivery from almost exactly the same position and, again, the Dutch look uncomfortable defending it, but the ball just runs past Orlaith Conlon at the back post.
Kay-Lee de Sanders scores for Ajax Women. The lead lasts just two minutes as Munsterman's corner finds Kay-Lee de Sanders with a free header, and it trickles into the corner.
Rianna Jarrett scores for Wexford Youths Women. Straight from kick-off, Wexford win a free kick, which is floated in by Emma Hansberry and Rianna Jarrett finds the corner with a bullet header.
One minute added on here and Wexford look set to make it in on terms.
Ajax pushing on a bit as half time approaches. Wexford clear a cross just outside the box, where Zeeman can allow it bounce and volley, but she puts it over the top.
A free kick in a good position on the left for Hansberry, but it's a wasted effort as she overhits her attempted cross and it goes over.
Great work from Katrina Parrock on the left as she pressurises a defender and wins the ball at the edge of the box. She's pulled back but manages to get through and get volley away, which is saved, but the referee has already called it back for the foul.
Once again Wexford's last-ditch defending stands to them. Zeeman looks to be through on the right but Doireann Fahey gets herself in a good position to nick the ball away.
Wexford are being put under a bit more pressure in their own half now and are having to resort to kicking the ball up the pitch to relieve it. A bit more composure is needed.
A corner from Munsterman finds the centre-half Line Roddik at the back post, and she wins the header, but she can't steer it on target.
A quick Hansberry free-kick catches Ajax napping and Sinnott has time and space to pick out a cross on the right. She puts it in a good area towards Riann Jarrett, but Ubachs claims it decisively.
Wexford play themselves into trouble as a clearance is headed straight back and Ellen Jansen looks to have the beating of Lauren Dwyer, but the defender does just enough to push her wide so that her shot finds the side-netting.
Big chance for Ajax as, for once, Vanity Lewerisa gets the better of Nicola Sinnott and sends a ball across the box that's met by Verhoeve, and it takes a fine piece of brave goalkeeping from Dollard to take the ball off her toe. That should have been 1-0.
A bit of trouble from Kelly Zeeman here. She was caught on the ankle by Kylie Murphy and seemed to shrug it off before pulling up. It looks like she'll be OK to continue for now.
First proper chance for Ajax and it comes at the end of a period of patient pressure, as Liza van der Most is teed up on the edge of the area, but her shot is harmlessly straight at Dollard.
First chance for Wexford and it's an ambitious effort from Emma Hansberry. Aisling Frawley picks out her run from midfield down the right channel and she volleys first-time from 35 yards. For a moment it looks like the ball may kick up and trouble Marieke Ubachs, but she deals with it relatively comfortably.
Wexford are very slow to react to a hopeful ball in the box from Kika von Es, and it bounces all the way through to Soraya Verhoeve. She looks to pick out Munsterman for what would be a simple finish, but it's well-intercepted by Orlaith Conlon.
More promising from Ajax as they do drag Wexford out of shape and Marthe Munsterman looks to get on the end of a pass at the edge of the box, but she's well shepherded away by Emma Hansberry. Good defending.
Ajax have had a lot of the ball, as you'd expect, but like Wexford are struggling to string anything substantial together in their passing. Loose balls are letting them down each time.
Slow enough start here as both sides feel each other out. An early touch for Youths keeper Ciamh Dollard, and she slices the ball out for an Ajax tthrow, which comes to nothing.
