Harlequins wrapped up a comfortable 20-9 victory over Connacht in the Amlin Challenge Cup but still slipped to second in Pool One.
Tom Guest, who switched to number eight in the absent of the unwell Nick Easter, gave Quins an ideal start when he sliced through from 35 metres, and then made a key contribution to a second try for the team 10 minutes into the second half when he made a break before playing a long ball out for Mike Brown to supply the finish.
Nick Evans converted both, and the fly half's two first half penalties gave Quins a healthy 13-6 half-time lead. Opposite number Miah Nikora had also been on target with two first-half penalties, but his second half effort was not enough to pull Connacht back into the contest as Brown had already scored seven minutes earlier.
Bayonne are top of the pool on try count following a 65-7 victory over Italian side Cavalieri Prato which featured four tries for centre Sam Gerber.
