Post Time: 1:30 ET
Track: Colonial Downs (3rd Race)
Horse: DEADPAN

DEADPAN was primed for this dueling for the lead at longer as he heads back to dirt where his last start on the main track 3-back was a front running victory. Beaten favorite a couple of times on dirt in 2025 finishing 2nd best earlier this year over the Colonial main track in a much tougher allowance spot. – Art Gropper | Get Past Performances for this race

Post Time: 2:13 ET
Track: Woodbine (3rd Race)
Horse: CLASSIC DISCOVERY (#2, 6-1)

CLASSIC DISCOVERY saved ground on the turn before closing between rivals to end up third in a blanket finish when moving out to seven-eighths over yielding ground on the inner turf most recently. She's bred to run on and should be dangerous in this two-turn inner turf route if able to save ground on the freshest part of the course. – Ron Gierkink | Get Past Performances for this race

Post Time: 2:37 ET
Track: Belmont at the Big A (4th Race)
Horse: RAFA JUNIOR (#5, 6-1)

In a race where none of the firsters check all the boxes, at least RAFA JUNIOR has some decent pedigree for these conditions; new sire Caracaro's progeny have won 5 of 19 (26%) turf sprints so far, and damsire Shackleford is also a good turf sprint influence; Rick Dutrow isn't necessarily known for debut success, but he did win with a firster in a turf sprint at Saratoga off modest workouts. – David Aragona | Get Past Performances for this race

Post Time: 2:56 ET
Track: Gulfstream (5th)
Horse: STARSHIP DISCOVERY (#3, 4-1)

STARSHIP DISCOVERY ran great in her debut even tough it was two turns on the grass. That was as a 3YO so she figures more mature at age 4. We know she can fire fresh and that she likes this sod. Works are perfect. – Scott Ehlers | Get Past Performances for this race

Post Time: 3:54 ET
Track: Woodbine (6th Race)
Horse: ARGOS (#1, 8-1)

ARGOS is a DRF Best Bet (Ron Gierkink). | Get Past Performances for this race

Post Time: 4:01 ET
Track: Gulfstream (7th Race)
Horse: CHROMOTION (#1, 20-1)

CHROMOTION might find the front at a huge price and forget to stop. Off form runners like this are often let go on the front end in the belief they will tire. Sometimes they do...sometimes they get a confidence boost and don't. His return try had him right there with a furlong to go. – Scott Ehlers | Get Past Performances for this race

Post Time: 4:36 ET
Track: Los Alamitos Race Course (2nd Race)
Horse: CONCORD BRIDGE (#7, 4-1)

CONCORD BRIDGE shortens to a sprint aftger dueling and tiring both routes this summer at Del Mar. The last time 'BRIDGE ran short, he won a maiden sprint by four lengths with a figure high enough to win this allowance. The productive trainer-jockey combo of Ellis and Welfin Orantes (8 for 17 since February) could sweep the early double. – Brad Free | Get Past Performances for this race

Post Time: 4:47 ET
Track: Belmont at the Big A (8th Race)
Horse: AMERICAN GRANT (#7, 8-1)

There figures to be at least a fair early pace in this race, and that's what AMERICAN GRANT (#7, 8-1) needs to be most effective; he just never looked comfortable rating at the back of the pack last time; even though the fractions look fast, that field was pretty bunched and he was pulling behind horses after a slow start; ran well to win against a decent field two back, and retains one of the best turf jockeys in the colony. – David Aragona | Get Past Performances for this race

Post Time: 5:00 ET
Track: Colonial Downs (10th Race)
Horse: IN THIS MOMENT (#6, 7-2)

IN THIS MOMENT is a lightly raced filly making just start 5 of career late in her 4-year-old season. Made her career debut on Colonial Downs grass but has improved considerably since that unveiling 1 year and 1 week ago. Beat the 2-back runner-up finisher who broke her maiden next-out in a Pimlico MSW with an 83 Beyer. – Art Gropper | Get Past Performances for this race

Post Time: 5:02 ET
Track: Woodbine (10th Race)
Horse: TWIN CITY (#3, 15-1)

TWIN CITY won his season opener going seven-eighths on the Tapeta with an 88 Beyer in a conditioned allowance/optional claimer before two straight dull outings on turf. He's coming off an improved third in the G2 King Edward on the main turf and could make some noise at a square price in this G3 on the Tapeta. – Ron Gierkink | Get Past Performances for this race

Post Time: 5:45 ET
Track: Los Alamitos Race Course (4th Race)
Horse: ROGUE SON (#3, 5-1)

A subtle class drop from open $6.25k claiming to N3L $6.25k claiming benefits ROGUE SON. His last "win" was at LRC in December; he was disqualified for interference and placed third. 'SON has never raced at this low level, there is enough pace to flatter his closing rally. – Brad Free | Get Past Performances for this race
