Umaga scored two tries for the Hurricanes

The match was marred by some dangerous tackling and the dismissal of Cats hooker Hanyani Shimange just on half-time.

He was handed a two-match suspension on Sunday.

Springboks fly-half Andre Pretorius kicked a penalty goal to give the Cats a 3-0 lead before Umaga went over twice to extend the Hurricanes lead to 14-3.

However, the Cats started putting some good moves together and rallied for a 15-14 lead at half-time with two tries from Pretorius.

The Hurricanes took advantage of their one-man advantage throughout the second half, with scrum-half Jason Spice scoring soon after the re-start.

The six point lead was whittled away by two penalties by Pretorius, who finished with 21 points, but the home team was unable to keep up the pressure.

The Hurricanes earned a bonus point in the 68th minute when Brent Ward scored a try, converted by David Holwell.

The Blues opened up a four-point lead at the top after scoring nine tries to earn a fourth bonus point from their first four matches.

Blues coach Peter Sloane said: "That was quite possibly the best we have played that I have been involved with."

Reds coach Andy Slack was downcast after their fourth loss of the season, which leaves them rooted to the foot of the table.

Slack said: "We just could not get our hands on the ball. I thought we were still in with a shot at half-time but we made mistakes and paid the price."

The 42-point winning margin was the Blues' biggest against the Reds and the first time the visitors had conceded 50 points in the history of the Super 12.
