The relevant bit is . . .
"The Grade 2 Betfair Game Spirit Chase at Newbury on Friday was undoubtedly the highlight of the week in the 2m to 2m5f chase division, although there were a couple of other races that pushed it close, writes Mark Olley.
It’s not often that you witness a novice treat older rivals with total contempt, especially in a Grade 2 contest, and in a new course record time, but that’s exactly what Sprinter Sacre did. Nicky Henderson’s hugely exciting novice never came off the bridle in beating stable-mate French Opera and gave me the same kind of tingle up the spine that Kauto Star did when winning the Lancashire Chase at Haydock back in 2006 prior to his first Gold Cup.
French Opera won this race last season, along with a Grade 2 at Sandown, and also ran a creditable sixth in the Champion Chase. He’s just below the very top-class 2m chasers, but is a high-class 2-miler and seldom runs a poor race.
I based the race around French Opera (162) and the third placed I’m So Lucky (150) – who received 10lb and was beaten just over two lengths by French Opera – and have them both running to their pre-race marks. This left me with the decision on what to call the facile six-length winning margin. In the end I settled on 12lb which puts Sprinter Sacre on a new mark of 169 and makes him the highest rated novice in years.
This compares favourably with recent winners of the Game Spirit – French Opera was 164 in 2011, Master Minded was 173 in 2010 and 170 in 2008, while Well Chief was 169 in 2007 (the race was abandoned in 2009). It also puts Sprinter Sacre into second place in the 2m chase division, behind the 177-rated Sizing Europe."
