SARACENS recovered from a poor start to comfortably earn the bonus point against Richmond.
Two tries from Jodie Rettie and scores from Rocky Clark, Hannah Botterman, Vicky Fleetwood and Poppy Cleall gave Sarries the win.
Richmond got off to a flying start as second row Rowena Burnfield crashed over to score inside five minutes and Abi Chamberlain kicked the extras.
Saracens dominated the territory but lacked a clinical edge for large swathes of the first half.
That changed as Rettie finished a driving fivemetre scrum at the half 's midpoint and Lisa Martin kicked the conversion to level the scores.
Sarries continued to press and with seven minutes left in the half, Clark's converted try put them ahead for the first time.
They had to hang on until half-time though, as Richmond had a spell of possession right in front of the Saracens try-line.
Saracens looked better after the break and following a string of scrums on the Richmond line, Rettie crossed for her second try in the 47th minute.
The floodgates opened and Botterman scored the bonus-point try in the 53rd minute.
Ten minutes later Sarries went through the forwards again and replacement Fleetwood scored the fifth try, Martin adding her fifth conversion.
Cleall added the sixth try with eight minutes to go from another drive from the pack, Martin again converting to seal victory.
