Wasps took advantage of Saracens' defeat to Bath on Saturday to move a point behind the Premiership leaders with a 26-12 victory over Worcester Warriors.
Brendan Macken got the visitors off to a fast start at Sixways Stadium with a try in the opening minute and Wasps never looked back as Dan Robson added a second score five minutes into the second period.
The boot of Rob Miller ensured the scoreboard kept ticking over with four penalties, while all Worcester could muster was four kicks from Jamie Shillcock.
Victory sees Wasps climb back into second place above Bath, while Worcester's losing run extends to five matches and they sit second bottom.
Sunday's second match saw a tight encounter at Kingston Park as Newcastle Falcons clung on to secure a 38-32 bonus-point win over Harlequins.
The hosts dominated proceedings in the first half as they racked up 21 points to Quins' eight, but visitors put up a valiant effort in the second half.
Karl Dickson scored twice and Tim Visser crossed the line in the closing stages as Quins finished the match two bonus points, but the Falcons had done enough to secure the win and move level with their opponents in the table.
