Zebre out-scored Ospreys by six tries to two in their 37-12 success at Stadio Sergio Lanfranchi, with Mattia Bellini scoring a fine hat-trick.
Meanwhile at Kingspan Stadium, Nick Timoney scored twice as Ulster earned a bonus-point success over Glasgow Warriors despite Callum Gibbins’ brace.
Here are five of the best tries from the weekend’s action.
Gabriele Di Giulio (Zebre)
Zebre were already 30-7 up with 70 minutes gone but that didn’t stop them adding their sixth and final try of the afternoon against the Ospreys.
Neat line-out ball eventually found Bellini in midfield who offloaded out of the tackle to a rampaging replacement in Di Giulio who stormed through.
There was no stopping the winger as he forced his way over the line and beneath the posts to allow for a simple Carlo Canna conversion.
Reuben Morgan-Williams (Ospreys)
A moment of fine play from 20-year-old Morgan-Williams will be one of the positives Ospreys can take from their defeat out in Italy.
The young scrum-half threw an elaborate dummy before sneaking around the side of the ruck and showing an excellent side-step to beat the last defender.
That saw him over the tryline with the young Ospreys man diving underneath the posts.
Mattia Bellini (Zebre)
There was a hat-trick for Bellini on the day but this was his stand-out score as Zebre once again demonstrated their willingness to play with width.
Giulio Bisegni’s kick creates the chance for the Italians and nobody was beating Bellini to the bouncing ball as he dotted down in the corner.
Nick Timoney (Ulster)
A pair of scores for Timoney saw Ulster to a bonus-point win and his first was an excellent finish in the left corner to complete a neat backs move.
Six Nations hero Jacob Stockdale was involved but it was the offload under pressure from Stuart McCloskey that really created the opportunity.
Timoney still had plenty to do though and he got low to bury his way over the line and get a vital score to extend Ulster’s advantage.
John Cooney (Ulster)
Cooney surpassed 200 points for the season and this was a brilliantly typical scrum-half score from the base of the scrum.
Credit must also got to the Ulster pack for a rock-solid scrum which allowed the experienced 27-year-old to dart right and get a crucial score.
