Veteran centre Keith Senior celebrated his 300th appearance for Leeds with a brace of tries in a vintage display as the engage Super League champions demolished Hull 46-16 at Headingley Carnegie.

The 33-year-old former England international, one of only five men to have played in all 14 seasons of Super League, struck midway through the first half for the 151st try of his Leeds career and added another on 66 minutes.

The evergreen three-quarter, who has just signed a new contract for 2010, also brilliantly carved out a 40-metre try for his winger, Ryan Hall, in another demonstration of his continuing value to the Rhinos.

Senior's fellow centre Lee Smith also produced an eye-catching two-try performance as the Rhinos easily avoided the humiliation of a fourth successive home defeat with a rampant eight-try display.

One-time leaders Hull had internationals Motu Tony and Gareth Raynor making their first appearances of the season and hooker Shaun Berrigan was back from a three-match absence with a knee injury to give their team a more representative look.

Leeds were without influential scrum half Rob Burrow, who failed to recover from a dead leg, and they lost hooker Danny Buderus within 10 minutes with a back injury.

By then, the champions were trailing 6-4 after Hull centre Richard Whiting had outjumped Hall to touch down skipper Lee Radford's high kick to the corner.

That try cancelled out Smith's sixth-minute effort for Leeds and Danny Tickle's conversion gave the visitors a surprise lead.

But Senior took Danny McGuire's razor-sharp pass to edge the Rhinos back in front and twice went close to adding a second try as the home side gradually took control.

Full-back Brent Webb took advantage of McGuire's kick, which ricocheted off an upright, to touch down on 35 minutes only for Hull centre Kirk Yeaman to hit straight back with a touchdown following Chris Thorman's grubber kick.

But Leeds had the final say of the first half when, five minutes into stoppage time, second rower Carl Ablett went through some poor tackling to score a solo try and Sinfield kicked his third goal to give them a 22-10 lead.

The momentum was clearly with Leeds and it took them just three minutes of the second half to extend their advantage.

They were gifted possession on halfway when Hull substitute Sam Moa knocked on without a tackler in sight and took instant advantage, with Sinfield sending the dangerous Smith through a chink in the visitors' defence to score his second try.

Whiting then intercepted Webb's pass to set up the position for Hull to press the Leeds line but the Rhinos' defence proved to be up to the task and they scored again on 58 minutes to pull well clear.

Another Hull handling error, this time from Radford, presented the Rhinos with another perfect attacking position and Senior powered through Yeaman to give Hall a clear run to the line.

Sinfield's fifth goal from six attempts put Leeds 34-10 in front but Radford made amends for his blunder when he took Richard Horne's short pass to score his side's third try.

Senior then took McGuire's pass to romp through a gaping hole in the tiring visitors' defence for his second try, which clinched a deserved man-of-the-match award, before Sinfield raced clear to score an opportunist eighth try in injury time.

The skipper took his goal tally to seven from eight attempts to finish with a personal tally of 18 points.
