It’s Preakness Day at Pimlico as the Maryland Jockey Club plays host to the final jewel in the 2020 Triple Crown. Selections provided by the 1/ST INDEX measure each contender against the 10 leading factors for each race. The 1/ST BET app looks at 52 handicapping factors and more than 200,000 past races to determine its AI selections. You can use the automated handicapping factors, or create your own factor filters to incorporate angles you prefer.

RACE 1 (11:00AM ET) // SELIMA S. ($150K) // 1 1/16 MILES (TURF)

4-DOMAIN EXPERTISE // 33%
2-GOLDEN VOICE // 20%
1-FLUFFY SOCKS // 14%
3-INVINCIBLE GAL (GB) // 9%

Notable: The 33% for Domain Expertise matches Preakness favorite Authentic for highest on the card by the 1/ST INDEX. The 5-2 morning line favorite is expected to get the day off to a formful start as the top 4 morning line choices match up with the computer.

RACE 2 (11:35AM ET) // G3 GALLORETTE S. ($150K) // 1 1/16 MILES (TURF)

3-SHE’SONTHEWARPATH // 31%
1-JULIET FOXTROT (GB) // 19%
8- VARENKA // 11%
6-STORM THE HILL 11%

Notable: The 1/ST INDEX is calling for an upset as 7-5 morning line chalk Juliet Foxtrot checks in a significant 12 points behind 7-2 morning line proposition She’sonthewarpath.

RACE 3 (12:10PM ET) // SKIPAT S. ($100K) // 6 FURLONGS (DIRT)

6-BRONX BEAUTY // 30%
5-BYE BYE J // 28%
1-CHALON // 11%
4-LIZA STAR // 10%

Notable: Solid prices on the top pair Bronx Beauty (9-2) and Bye Bye J (4-1) as the morning line favorite Chalon (5-2) rates far back in third on the 1/ST INDEX.

RACE 4 (12:46PM ET) // HILLTOP S. ($100K) // 1 MILE (TURF)

2-CHART // 30%
4-AMERICAN GIANT // 10%
3-CARAVEL // 10%
11-LUCKY JINGLE // 10%

Notable: The 20-point spread from first to second choice is tied for largest on today’s card, according to the 1/ST INDEX. Woodbine shipper Chart (5-1) is not the favorite, while morning line chalk Vigilante’s Way (9-2) is snubbed by the algorithm.

RACE 5 (1:22PM ET) // G3 MISS PREAKNESS S. ($150K) // 6 FURLONGS (DIRT)

5-MUNDAYE CALL // 29%
1-AIN’T NO ELMERS // 20%
3-FLY ON ANGEL // 17%
7-PRINCESS CADEY // 13%

Notable: Top two morning line choices Mundaye Call (7-5) and Ain’t No Elmers (7-2) hold steady atop the 1/ST INDEX as well. The interesting exotics horse here could be Princess Cadey (15-1), who will be rallying at a big price into an expected very hot pace.

RACE 6 (2:01PM ET) // G2 DINNER PARTY S. ($250K) // 1 1/16 FURLONGS (TURF)
7-FACTOR THIS // 26%
2-SOMELIKEITHOTBROWN // 25%
3-HEMBREE // 17%
6-DOCTOR MOUNTY // 10%

Notable: Even-money morning line favorite Factor This eeks out top billing in the 1/ST INDEX over Somelikeithotbrown (5-1). The latter surely will offer more value in the win pool based on that.

RACE 7 (2:42PM ET) // G3 FRANK J. DE FRANCIS MEMORIAL DASH ($200K) // 6 FURLONGS (DIRT)
5-LANDESKOG // 28%
3-EASTERN BAY // 19%
1-ADMIRAL LYNCH // 16%
4-LAKI // 12%

Notable: Landeskog appears a more than capable favorite in this spot at 5-2 in the morning line. Value player Eastern Bay (10-1) intrigues on price as a sharp local.

RACE 8 (3:22PM ET) // LAUREL FUTURITY ($150K) // 1 1/16 MILES (TURF)
8-HIDDEN ENEMY (IRE) // 18%
9-TIJUANA BRASS // 17%
10-NAUTILUS // 15%
4-KIDNAPPED // 11%

Notable: With the top 3 within 3 percentage points in the 1/ST INDEX, the algorithm makes this is the most competitive race on the card. Morning line favorite Pivotal Mission (3-1) doesn’t impress the algorithm, while 20-1 shot Tijuana Brass could blow up the tote.

RACE 9 (4:02PM ET) // JAMES W. MURPHY S. ($100K) // 1 MILE (TURF)

11-BUY LAND AND SEE // 30%
1-CHOCOLATE BAR // 10%
13-BYE BYE MELVIN // 10%
7-VANZZY // 10%

Notable: The 20-point spread from first to second choice is tied for largest on today’s card, according to the 1/ST INDEX. And it comes with an 8-1 morning line proposition in Buy Land and See. If the algorithm is on point, this could be a highly valuable runner in the multi-race wagers, as well as intra-race, in a race that looks very difficult on paper.

RACE 10 (4:41PM ET) // G2 BLACK-EYED SUSAN S. ($250K) // 1 1/8 MILES (DIRT)
5-BONNY SOUTH // 28%
8-HOPEFUL GROWTH // 14%
9-MISS MARISSA // 11%
10-LANDING ZONE // 10%

Notable: Solid favorite Bonny South (7-5 morning line) figures to out-class her rivals and doubles up her competition here, according to the 1/ST INDEX. Class riser Miss Marissa (12-1) adds exotics value.

RACE 11 (5:36 PM ET) // G1 PREAKNESS ($1M) // 1 3/16 MILES (DIRT)
9-AUTHENTIC // 33%
4-SWISS SKYDIVER // 14%
8-MAX PLAYER // 10%
7-NY TRAFFIC // 10%

Notable: The 33% for Authentic is co-highest on the card by the 1/ST INDEX, which surprisingly doesn’t share respect for second betting favorite Art Collector. Exotics value players in the Preakness may look to 15-1 price players Max Player and Ny Traffic.
