In the day’s late kick-off, Emma Sing converted a late penalty and give seventh-placed Gloucester-Hartpury a 15-12 win over Worcester, who remain one spot behind them in the table.
Gloucester-Hartpury were 12-0 up at the break after tries at the start and very end of the first half from Bethan Lewis and Sisilia Tuipulotu.
However, Worcester came back into it as Cat McNaney crossed in the corner 10 minutes into the second period.
Taz Bricknell then muscled over with 13 minutes left and Sarah Nicholas converted to level the scores at 12-12.
That led to a frantic finale before Gloucester-Hartpury were awarded a penalty with four minutes to go and Sing held her nerve.
