In yet another dominating performance during which they enjoyed 75 per cent possession, Manchester City scored their eight goals from 12 shots in target against their hapless opponents who scored what amounted a consolation goal 10 minutes into the second half.
However, Shaw alone proved too much for Bristol City scoring in the 13th, 25th, 41st minutes as City took a 4-0 lead into the interval.
Filippa Angeldahl scored the fourth in first-half stoppage time.
Julie Blakstad made it 5-0 early into the second half when she scored their first of her two goals in the 53rd.
Gracie Jane Patricia Pearse made it 5-1 two minutes later.
Shaw scored her fourth in the 75th to make it 6-1 before Blakstad made it 7-1 in the 83rd.
Jemima Dahou scored Manchester City’s eighth to complete rout in stoppage time.
For her exploits, Shaw took home match ball.
Prior to the match Manchester City manager Gareth Taylor, promised they would not take their second-tier opponents lightly.
"With some of the teams you play, there's not a huge amount of difference in level between the kind of top end of the championship to the bottom end of the WSL,” he said.
“I think it's just making sure that as a team, we are prepared, we're focused. We're not being neglectful of the opposition.”
They were not.
In a dominant display in which Manchester City took 27 shots, 14 on target, Shaw opened the scoring in the 16th minute. The three-time FA Women’s Cup champions doubled their lead when Chloe Kelly scored in the 38th minute as City threatened to run rampant.
Deyna Castellanos then scored on the stroke of half-time to send City into the break with a 3-0 lead.
Shaw was against first on the scoresheet with her second goal six minutes after the resumption before Julie Blakstad scored the first of her two goals in the 53rd minute.
Blakstad scored her second in the 78th minute to make it 6-0.
Shaw completed her hat-trick in the 87th minute to complete the rout.
