| Hand ride for Thought Process G2 San Clemente |
Welcome Friends to The Turk Blog, where I usually specialize in handicapping older horses running over a route of grass, with which I turn into exacta bets. Simple premise. Today I'm handicapping the Del Mar Oaks, and while only 3 YOs, I don like to get some looks at the next up and comers. My issue with the younger horses is they lack data. The more information as a handicapper you have, the better. With younger horses I modify my key angles slightly and I focus on class, wins at the distance, wins at the track, trainer intentions. 27 wins combined for the 11 starters. 3 Graded Stakes Wins. Best late speed is Edge of Mali (IRE) at 107 followed by Firenze Flavor at 102. Best early speed is Thought Process at 116 and the next closest is Slick (Ire) at 97. Slick (Ire) and Lush Lips have the best Turf Tomlinson's in mid 380's while Striver is best Distance Tomlinson at 409.
Let's take a look at Thought Process and her dominant win in the one mile San Clemente. Don't underestimate the power of the extra 660 feet today, but no one was catching her on this day.
19 July 2025: Dmr; The San Clemente G2; 1 Mile over Firm Turf
Casalu gave good chase running well past his Turf and Distance Tomlinson's. Tomlison's have thier place, especially in these younger horses.
Tomlinson Numbers were created by pedigree experts Leon Rasmussen and Leon Tomlinson in the 1970s and 1980s. They were designed to give horseplayers a quick numerical measure of how a horse’s breeding suggests it will perform under certain racing conditions such as turf, dirt, distance, or wet tracks.
The numbers are calculated from pedigree data. They look at how successful a horse’s ancestors—particularly the sire and dam—have been under a given condition. This produces a three-digit figure, where higher numbers mean the pedigree shows more strength for that surface or distance. For example, a turf Tomlinson of 380 or higher suggests strong turf ability in the pedigree, while a 250 would suggest little turf influence.
The Daily Racing Form began including Tomlinson Numbers in Past Performances in 1991. They quickly became popular with bettors because they help answer unknown questions, such as whether a horse trying turf for the first time might be bred for it, or whether a sprinter stretching out in distance may have the stamina in its bloodlines. They are especially useful for first-time starters, surface switches, and stretch-outs.
There are limits to Tomlinson Numbers. They do not measure actual ability, fitness, or class—only what the pedigree suggests. A horse with a high Tomlinson may still run poorly, and a horse with a low one may still succeed if its individual talent or training outweighs its bloodlines.
Remember what we are trying to do here, two separate tasks:
- Handicap (place in order) who should win.
- Exacta Bet: Who can beat my top win candidate who might finish in second.
