John Smit marked his Saracens debut with his first Heineken Cup try as he helped English champions Saracens notch a comfortable 42-17 bonus point start to their campaign.
The former Springbok skipper had tasted European action before during a short stay at Clermont Auvergne and he made a return to the tournament in the 58th minute as a replacement for fellow countryman Schalk Brits.
And it didn't take long for him to make an impact as he drove over for his side's fifth and final try in the 77th minute to round off a good day's work by the home pack.
But while Smit grabbed the headlines late in the day it was England prospect Owen Farrell who enhanced his growing reputation with a 22 point contribution with a try, four conversion and three penalties.
In fact, it was 16-3 to Farrell at the break and it wasn't until Britz put Dave Strettle over for a try six minutes into the second half with a delightful inside pass that Farrell's stranglehold o the scoreboard was broken.
Franco Smith's Benetton Treviso had won on the road in their domestic league at both Ulster and Glasgow this season, but found themselves outgunned upfront and outpaced behind. Even so, their defence never leaked and they hit back to score two tries in the final six minutes.
Replacement hooker Franco Sbaraglini got the first and then replacement lock Gonzalo Padro ensured a good ending with his 80th minute touchdown.
The bonus point victory took Saracens to the top of Pool 5 and they will travel to face Biarritz Olympique next weekend, while Benetton Treviso's second round assignment is at home against the Ospreys.
In Sundays other matches former Heineken Cup Champions Toulouse were made to work hard for an opening victory in this year's tournament, having to come from behind twice to beat a passionate Gloucester side.
The Cherry and Whites held the lead for long periods of the game, but clinical finishing from the hosts saw them claim a tight 21-17 victory.
Meanwhile, Glasgow Warriors snatched a late win over Bath at Firhill with lock Richie Gray scoring a try with the last play of the game to give his side a 26-21 victory.
The script looked set for Bath to come away with the win after debutant and World Cup winner Stephen Donald came off the bench to kick them ahead with four minutes remaining.
But Gray and the Warriors had the last word. Duncan Weir launched a drop-goal attempt with the clock showing red but his kick was way short and Bath failed to deal with the bouncing ball and Gray took his opportunity and divded under the posts to win the game.
