London Wasps grinded out a narrow 10-6 victory over Worcester in their Premiership clash at Adams Park on Sunday.
It was the hosts who controlled the first half with Simon McIntyre touching down and Stephen Jones adding a penalty as they led 10-0 at half-time.
Andy Goode responded for the visitors with a kick from the tee and a drop-goal, but they had to be content with a solitary point.
This was a battle between two teams who started the encounter in the lower reaches of the table, but both of them should be content with how they have fared in their opening five rounds.
Worcester struggled to score tries last season, but they have so far bucked that trend and touched down 12 times. However, it was the hosts that started the brighter and went ahead through McIntyre's first ever try in the Aviva Premiership.
Jones added the conversion before slotting a penalty to reward the High Wycombe-based outfit's early dominance.
Despite the visitors' change in attitude towards a more attacking mind-set, they had to rely on the defence to keep out a determined Wasps' side.
The Warriors managed to hold on until half-time but they still found themselves 10-0 in arrears. They came out with far more intent in the second period, though, and Goode's first points of the afternoon took Worcester to within losing bonus-point territory.
A long-range drop-goal from the stand-off eroded into that lead further as the hosts became nervy.
Jones had the chance to ease the tension, but his 67th minute penalty attempt missed, although it wasn't to matter in the end as they held on.
Drop goal: Goode
