Pat Cummins immediately reviewed.
Replays showed a deviation but snicko had no obvious spike. It was given out nonetheless and Jaiswal was on his way for 84.
Jaiswal confronted the umpires and wasn't happy.
He didn't have much sympathy.
"I think it's a fair decision, I think it brushed the bat and the glove. Maybe Jaiswal didn't feel it but visually you can see the deflection," Mark Waugh said on Fox Cricket.
"I think it was quite obvious on the screen it hit the bat and top of the glove," Michael Vaughan added.
Post-game, Cummins believes Jaiswal knew he was out the moment they decided to review.
"I think it was clear that he hit it. Heard a noise, saw deviation so it was absolutely certain that he hit it," he told reporters.
"As soon as we referred it, you could see him drop his head and basically acknowledge he hit it. On screen, you could see he hit. Ultra-edge, I don't think anyone has complete confidence in and didn't really show much but fortunately there was other evidence to show it was out."
