Actually it does make sense from a Beyer standpoint that Mendelssohn was sitting on a poor race. Not "last place" poor, mind you. But he still had a very regressive pattern to his races just on the surface. That's not looking into the manner and track conditions of his last race which produced the big BSF either. Track conditions and the early pace he was forced to run probably had a lot to do with how badly he faded late as well.
@ImNotSurpisedDonks!
If I may expand on this point with Mendelssohn's thorograph numbers over his last four races before the Derby;
7 1/4, 9, 5 1/2, -4 1/2
If you're not familiar with thorograph, the lower the number the better the performance was according to them, so him having a negative thorograph number is a huge effort by him. Especially since it was 10 points better on thorograph than he had ever ran before.
Now according to thorograph's own data going back 25+ years, horses who have improved their thorograph number by more than 3 points in their final prep before the Derby have seen 81% of them regress in the Derby itself, with 62% of them having regressed badly enough to receive what is classified as an X race (more than 4 point regression). And that's just with a 3+ point improvement. Not the ridiculous 10 point improvement that Mendelssohn had.
North American figure makers like Beyer or Brisnet numbers aren't given out for European runners for the most part beyond the occasional estimate. But Mendelssohn was given an 86 BSF for his BC Juvenile Turf win and then it was estimated that he got a 106 BSF for the UAE Derby. Without knowing what figure he would have gotten for the race in between (if given, it'd certainly be much, much closer to the 86 than 106 based on the thorograph and RPR he was given, which was 115 in both the BC race last fall and his first start this spring), that's a huge increase in his figure over a span of two races when considering the fact that the UAE Derby was Mendelssohn's 7th career race. Some improvement can certainly be expected going from 2 to 3 for him, but is he really going to be a 106 BSF in his 8th career start (the Derby) after having been maybe an estimated 85-90 BSF (tops) over his first 6 career starts? To me the 106 he earned is a clear outlier with him, as is the -4 1/2 he earned on thorograph.
Just on the surface he had the look of a regressive horse just based on that stuff alone, but when you factor in other things it looked even moreso. Like him only flying over and arriving at the track 5 days before the Derby and then having to spend two full days in quarantine before he was allowed to hit the track for the first time on Thursday. Or that "first time on dirt after turf" angle that exists in horse racing, and I think I talked about on here last year just before Good Samaritan took the Jim Dandy for a few of us. But then also consider the circumstances in which he earned that 106 BSF in the UAE Derby.
This spring at Meydan, which is where the UAE Derby takes place at, there were 17 races that were ran on the dirt over there. Out of those 17, 16 of them were won by a horse who rode the rail the whole way and led wire-to-wire. Mendelssohn`s UAE Derby win was one of those 16. Not including Mendelssohn, 13 of those 16 wire-to-wire winners have ran since. 12 of them regressed their next race according to their RPR with 11 of them regressing by more than 10 points. 8 of those regressed by 20 or more points on their RPR. The one horse who didn`t regress (1 point RPR improvement) returned in another dirt race at Meydan where it finished 2nd by following the wire-to-wire winner along the rail the whole way. What that tells us is that the way the Meydan track was playing had a huge say in the outcome of those dirt races, and those that got to the rail on the lead were seeing their performances being flattered significantly by the track. Including Mendelssohn`s performances where he earned that 106 BSF.
The 106 BSF he earned winning the UAE Derby is what it is. He ran a fast race. But that was also a 106 earned under a significant track bias that favoured him as evident by all the other horses who also got the same trip he did over the Meydan track and then regressed (most by a lot) when they couldn`t get that same rail trip on the lead in their next races.
People who bet Mendelssohn down to 6/1 made the mistake of thinking that the 106 BSF he earned was a true indication of his ability going into the Derby without considering the circumstances in which it was earned or considered the very regressive nature of his form when it came to pattern handicapping. Now the last place finish he got in the Derby isn`t indicative of his ability or what his true chances were either. But still.
I`m proud to say that our resident trifecta crushing Derby expert
@t6p would have never landed on a horse like Mendelssohn in this race. Nor would have
@BluntTrauma21. They know better when it comes to pattern handicapping and when horses run what looks like an outlier figure. They know that, even though those "jump up" types do win on the rare occasion, they are terrible bets in the long run regardless if it`s in the Derby or not.
