The boot of Ben Botica has given Harlequins a 21-12 victory over Bath at Twickenham Stoop in round two of the LV= Cup.
Botica kicked over all of his side's points in the first half, while Stephen Donald scored two penalties of his own as the hosts went in 15-6 ahead at the break.
Donald scored again at the start of the second half to get the visitors to within six points of their opponents before a fourth penalty of the night edged Bath even closer.
However, two late penalties from replacement Louis Grimoldby helped get Quins over the finish line.
