But the Waratahs never went close to scoring after Beale limped off before halftime with an ankle injury in a tight 19-12 victory.
NSW coach Michael Cheika will closely monitor Beale's progress before the Waratahs head to New Zealand on Thursday for an Anzac Day showdown with the Blues at Eden Park.
"He just jammed his ankle a little bit, so there's a bit of swelling there," Cheika said.
"He'll take a couple of days off now and see how he fares in relation to the preparation for Auckland."
Foley said Beale "was pretty confident in the sheds after the game" and the Waratahs No 10 was desperate for his playmaker to face the Blues.
"The attack's not far away from clicking," Foley said.
Cheika has challenged his players to persist with their daring ball-in-hand style as the countdown to the finals begin, but knows the Waratahs must cut their mistake rate against the dangerous Blues.
"They've got firepower and at Eden Park, of course on Anzac Day, it's going to be a pretty big day for everyone involved and they're a team that can score tries," Cheika said.
"But them playing like that opens up opportunities for us as well.
"There's a different dynamic with us against a team like that as opposed to us and a team like the Bulls.
"They're very dangerous in attack, especially off broken play. So errors will kill us."
Skipper Dave Dennis believes the fourth-placed Waratahs are positioned well to make a finals charge.
"Now we face two New Zealand teams where I think our game will be suited to what they're going to throw at us," he said.
"We've just got to keep sticking to what we believe in, our style of rugby, and we'll get some good results."
