South African trainer Mike de Kock is set to make history Saturday at Churchill Downs when the talented Mubtaahij will become the first South African-based horse to compete in the Kentucky Derby. Here is the 2015 Kentucky Derby Cheat Sheet from TDN Senior Editor Steve Sherack and TDN Racing Editor Brian DiDonato.

#1 OCHO OCHO OCHO (c, Street Sense--Winner, by Horse Chestnut {SAf})

T: J Cassidy. J: E Trujillo. - 50-1

BD: Looked like a legitimate Derby chance at the end of last year, but just hasn't done enough in his two tries this season to warrant serious consideration... Post really does him in.
SS: Game Jackpot winner has done little at three to merit a look here... One of the first tosses.

#2 CARPE DIEM (c, Giant's Causeway--Rebridled Dreams, by Unbridled's Song)

T: T Pletcher. J: J Velazquez. - 8-1

SS: For me, he's the complete package... With a pedigree that screams distance, last year's $1.6-million OBS March co-topper immediately showed his class with a wire-to-wire debut win going 5 1/2f at the Spa... The most important race of the MGISW's career, experience wise, may have actually come in defeat when a well-beaten second after rallying from far back into a hot pace in the BC Juvenile... Tactical enough to sit the right trip and won his two preps with something left...Top pick.
BD: Steve and I couldn't differ more in our opinions on this one... I don't like him at all. He hasn't run a particularly fast race, and won a decidedly sub-par renewal of the Blue Grass last time. Strikes me as a runner who will blink when he faces some adversity.

#3 MATERIALITY (c, Afleet Alex--Wildwood Flower, by Langfuhr)

T: T Pletcher. J: J Castellano. - 12-1

SS: An undefeated runner with the highest Beyer Speed Figure of his crop is the co-fourth choice on the morning-line... Just shows you how deep a field this is... Plenty of ability, but lack of seasoning is impossible to ignore...
BD: Liked him last time in the Florida Derby, and he's done absolutely nothing wrong so far in his career, but this strikes me as a case of too much, too soon. Might be your Haskell winner.

#4 TENCENDUR (c, Warrior's Reward--Still Secret, by Hennessy)

T: G Weaver. J: M Franco. - 30-1

BD: Maybe it makes no sense to like Frosted and toss this horse, but his effort last time was just too sharp of an improvement for me to take at face value... Also not sure he'll relish 10 panels.
SS: May have already run his Kentucky Derby when finishing a clear-cut second with a perfect trip after leading in the stretch at 21-1 in the Wood... Can't see him doing it again.

#5 DANZIG MOON (c, Malibu Moon--Leaveminthedust, by Danzig)

T: M Casse. J: J Leparoux. - 30-1

SS: Bounced back with a solid runner-up effort in the Blue Grass after a very disappointing performance over the tricky Tampa surface... With a deep Phipps female pedigree on his page, the Classic distance may be right up his alley... Interesting longshot to consider for a small piece.
BD: I guess there's no reason he can't clunk up for a piece, but I'm against horses coming out of the Blue Grass and other bombs interest me more.

#6 MUBTAAHIJ (IRE) (c, Dubawi {Ire}--Pennegale {Ire}, by Pennekamp)

T: M de Kock. J: C Soumillon. - 20-1

BD: Anyone who has a strong opinion on this horse one way or the other is either kidding themselves or a much better handicapper than I am... This seems like a big ask, and it's hard to know who he was really beating in Dubai, but he has been extremely visually impressive while enjoying some very easy trips. Hard to toss out completely, but also hard to back with any confidence.
SS: Certainly proved that he deserves to be here with a pair of sensational wins in Dubai and you know the distance won't be an issue... The price should be right if you decide to back him, but at the end of the day, isn't this a tall enough task without having to travel halfway around the world, too?

#7 EL KABEIR (c, Scat Daddy--Great Venue, by Unbridled's Song)

T: J Terranova. J: C Borel. - 30-1

SS: Graded winner over this course should benefit from a textbook Calvin ride in this speed-laden affair, but hard to imagine that it will be enough to take him over the top... Pass.
BD: Has accomplished a lot and earned plenty of money, but has just always struck me as being a cut below the best of this crop... Presence of Borel is sort of interesting, but may deflate his price.

#8 DORTMUND (c, Big Brown--Our Josephina, by Tale of the Cat)

T: B Baffert. J: M Garcia. - 3-1

SS: Unbeaten, battle-tested and still appears to be improving... Physically imposing son of Big Brown looks like he could be the speed of the speed, but will certainly have to run hard every step of the way to get Bob Baffert his fourth Derby win... Worthy of favoritism and everyone knows it.
BD: There really aren't many knocks on him other than the question of whether he's too quick for his own good and might get sucked up into a quick pace. The hype is warranted, but how short a price can you really take against this bunch?

#9 BOLO (c, Temple City--Aspen Mountain, by Chief Seattle)

T: C Gaines. J: R Bejarano. - 30-1

SS: If you buy into the theory (like I do) that a top-flight grass runner will typically give you at least one really big effort on the dirt--see his third-place finish with a career-high 101 Beyer in the San Felipe--this son of Temple City is not for you... Already looking forward to his return to the lawn later this summer.
BD: Endured wide trips in both of his dirt races, and was far from embarrassed in either effort... Hails from the family of Derby winner Mine That Bird and there's that whole ‘turf horses like Churchill' angle to consider... Exotics candidate.

#10 FIRING LINE (c, Line of David--Sister Girl Blues, by Hold for Gold)

T: S Callaghan. J: G Stevens. - 12-1

BD: Flying squarely under the radar despite some solid credentials... Wouldn't want to toss completely because of his price, but others appeal more.
SS: Easily one of the most forgotten runners in the field... Went pound for pound with the mighty Dortmund and won with something left while setting a new track record at Sunland... Has made a very favorable physical impression since arriving from So Cal and may offer the best value in the field... Disregard at your own risk.

#11 STANFORD (c, Malibu Moon--Rosy Humor, by Distorted Humor)

T: T Pletcher. J: F Geroux. - 30-1

SS: Thought he could be a star in the making after his Monmouth debut last summer and still haven't gotten over his tough Louisiana Derby defeat... Pace scenario doesn't bode well for him, but will still be playing some saver tickets.
BD: Has set fairly average paces in his two route attempts in which he crossed the wire second... Will either be a pace casualty, or will fail to make the lead and get out-kicked by others.

#12 INTERNATIONAL STAR (c, Fusaichi Pegasus--Parlez, by French Deputy)

T: M Maker. J: M Mena. - 20-1

BD: The reason you're not supposed to like him is that he's had perfect trips in each of his last three outings, but then again, what if he gets the same trip here? He's a picture of consistency and has the right running style to work out another smooth journey, and if he does, he's going to hit the board at the very least unless all the potential monsters show up with their best... Can't leave him off my tickets.
SS: Feel exactly the same way... Phenomenal job by Miguel Mena riding this son of the 2000 Derby hero to three straight wins at Fair Grounds with nearly identical ground-saving trips... Doesn't have the same flash as the main headliners, but is awfully hard not to respect while riding a very hot hand.

#13 ITSAKNOCKOUT (c, Lemon Drop Kid--Stormy B, by Cherokee Run)

T: T Pletcher. J: L Saez. - 30-1

SS: The only ‘KO' to make headlines Saturday evening will be in Las Vegas during the blockbuster Mayweather/Pacquiao fight... Hard to get in his corner. BD: Shouldn't have been put up in the Fountain of Youth, and was a complete no-show in the Florida Derby... Hard to like.

#14 KEEN ICE (c, Curlin--Medomak, by Awesome Again)

T: D Romans. J: K Desormeaux. - 50-1

SS: Has been a very frustrating horse to follow thus far--will let BD expand on that--but the king of the gallop out will finally get his desired trip here... This year's Golden Soul/Commanding Curve?
BD: On paper, he's nowhere close to good enough--and he probably isn't to actually win--but he has that look of a horse who blows up the Derby tri or super... Or maybe I've been getting tricked by his gallop-outs. Toss Romans (Dullahan, Paddy O'Prado) runner completely at your own risk... Or do, and you'll probably look smarter than me.

#15 FROSTED (c, Tapit--Fast Cookie, by Deputy Minister)

T: K McLaughlin. J: J Rosario. - 15-1

BD: He hasn't garnered the hype of the top few favorites, but his performance in the Wood Memorial was in many ways just as good as blowout wins from American Pharoah, Dortmund and Carpe Diem... He first caught the eye with a valiant runner-up effort in last year's Remsen, and put it all back together last time despite a no-cover trip behind a slow pace... Distance doesn't seem like a major issue, and the price should be right.
SS: Did they finally figure this son of Tapit out or did he just beat up on a very weak field in his return to his favorite racetrack in the Wood? Should get a dream set-up if he's good enough; just can't seem to trust him 100% off his prior form, though.

#16 WAR STORY (g, Northern Afleet--Belle Watling, by Pulpit)

T: T Amoss. J: J Talamo. - 50-1

SS: Wide trips haven't exactly helped while chasing home International Star this spring and like the way he's been moving over the Churchill surface during his morning preparations... Will still need to step up his game in a big way to factor here, though.
BD: Always had tougher trips than International Star in his three stakes at the Fair Grounds, but also lacked the kick to make up for it... Seems like a cut-back candidate.

#17 MR. Z. (c, Malibu Moon--Stormy Bear, by Storm Cat)

T: D W Lukas. J: R Vazquez. - 50-1

BD: Almost beat Dortmund and Firing Line at the end of last year, but hasn't stepped forward at all from there... Consistent and a check-getter, but would be shocked if he made an impact here.
SS: Has shown serious heart holding up through a grueling 12-race campaign without a layoff line, including some epic throwdowns in the Jackpot, Futurity, and Southwest... But c'mon, he's still eligible for a NW1X!

#18 AMERICAN PHAROAH (c, Pioneerof the Nile--Littleprincessemma, by Yankee Gentleman)

T: B Baffert. J: V Espinoza. - 5-2

BD: What can you say? Last year's champion juvenile has done nothing but continue to impress in two outings this year, and he's definitely worthy of favoritism. I've still got some questions about his dam side pedigree for 1 1/4 miles, however. I'll use him defensively in the pick four, but I'm going against him in intra-race bets.
SS: His legend seems to be growing--if that was even possible--since his jaw-dropping bullet workout beneath the Twin Spires Sunday... Not smart enough to make him my key horse, but won't exactly be leaving him off any tickets, either...No reason to believe that he isn't the real deal.

#19 UPSTART (c, Flatter--Party Silks, by Touch Gold)

T: R Violette Jr. J: J Ortiz. - 15-1

BD: Boasts several fast races, and will likely benefit from the dynamics of this one. He was probably closer than he wanted to be in his Florida efforts because the fields were a little shorter, but he should be able to take back a little bit more here and make one run... The distance shouldn't be a problem, and he seems to have bounced out of a very minor illness no worse for wear. Post isn't ideal, but hopefully solidifies an off-the-pace strategy.
SS: NY-bred is plenty talented and ran one of the faster preps of the season in Holy Bull comebacker... Big fan of his, but not so sure that this 10-furlong trip will bring out his best... I guess you can't use them all.

#20 FAR RIGHT (c, Notional--Zindi, by Vindication)

T: R Moquett. J: M Smith. - 30-1

BD: Has displayed a nice closing kick, but not sure he has the running style or the pedigree to be the type who clunks up for a piece in the Derby-- seems more like a sprinter/miler type.
SS: Hard not to pull for a $2,500 yearling buy in a race of this magnitude... And like International Star, he has displayed the ability to rally through traffic... At the end of the day, though, other longshot stretch-runners seem a bit more appealing.

#21/AE Frammento (c, Midshipman--Ginger Bay, by Golden Missile)

T: N Zito.

BD: Couldn't possibly fathom.
SS: Bigger upset than Mine That Bird?

#22/AE Tale Of Verve (c, Tale Of Ekati--Verve, by Unbridled)

T: D Stewart.

SS: I'm not even looking at this horse's past performances.
BD: Well, he should like the distance and he's by the right trainer to spice up the exotics. Kind of hope he doesn't get in so I can save a few bucks.
