Spirited Welsh performance gains a point in Slovakia.
Wigan striker Keiffer Moore epitomises a battling effort by Ryan Giggs' men.
Wales kept their hopes of qualifying for next years Euro alive with this competitive draw in Tranava.
They dominated the first period and, needing a result, took the initiative from early on.
With Gareth Bale and Manchester United rising star Daniel James providing the threats from the wide positions and Wigan's Kieffer Moore as the traditional centre forward.
Bale guided a fine header onto the goalframe before Moore comfortably converted a James cross on 25 minutes.
It was a well deserved lead for the visitors.
They did however need an excellent block by RB Leipzig's Ethan Ampadu to prevent a Slovakia goal following a loss of possession.
Going into the interval one goal ahead coach Ryan Giggs could contemplate a solid all-round effort with Charlton's Jonny Williams a prominent livewire in midfield.
But perhaps inevitably they could forsee more from the Slovaks in the second 45 minutes.
And so it was on 53 minutes when a weak defensive header reached Juraj Kucka who volleyed in the equaliser from the edge of the area.
For a while the momentum switched to the home side and goalie Hennessey had to be alert in the Welsh goal.
Often instrumental in their threats was the vastly experienced Marek Hamsik (now based in China) offering dangerous passing and movement.
But the Welsh held firm and striker Moore, in only his third international, kept battling up front.
Though he must have been relieved to see central defender Gyomber get a second yellow card late on.
Ultimately it was a merited draw for Wales and they would continue to compete in Group E of the Euro qualifiers.
