**Sunday 10 May 2026, 15:40 BST. Leopardstown Racecourse. Cashel Palace Hotel Derby Trial Stakes, Group 3, 1m2f. Going: Good.**

**James J Braddock (9/1, Joseph O'Brien / Dylan Browne McMonagle) wins the 2026 Leopardstown Derby Trial** -- a short-head defeat of the 5/6F **Pierre Bonnard (Aidan O'Brien / Wayne Lordan)**, with stablemate **Endorsement (7/2)** third. **Pierre Bonnard's Epsom Derby ante-post price drifted from 6/1 to 14/1 with Betfred** after a second consecutive defeat as odds-on favourite -- the Critérium International winner's Derby supplement now looks unlikely.

**Result:**

- **1st James J Braddock (9/1)** -- J P O'Brien / Dylan Browne McMonagle
- **2nd Pierre Bonnard (5/6F)** -- A P O'Brien / Wayne Lordan -- short head
- **3rd Endorsement (7/2)** -- A P O'Brien / R Moore (or Coolmore senior jockey, confirm)
- 4th-5th: Straight Up (A O'Brien) + Shaihaan (Donnacha O'Brien)

**Joseph O'Brien post-race [Racing Post]:**

*"The Derby looks a relatively open race. This guy is one of the contenders now, having won a trial."*

**Race shape:** Endorsement led for much of the race, tracked by Pierre Bonnard in 2nd. Wayne Lordan asked for maximum effort inside the 2-furlong pole; Pierre Bonnard began to make gains on the leader. **But James J Braddock, ridden patiently by Dylan Browne McMonagle, came with a strong late run** to nab the odds-on favourite on the line.

**Editorial reset.** Our [Leopardstown Derby Trial 2026 preview](/racing-news/leopardstown-derby-trial-2026-preview/) had Pierre Bonnard at 5/5 trends as the format-cleanest pick at Evens-F, with a structural longshot warning ("the longshot from the favourite-yard pattern"). The longshot pattern fired -- but from **Joseph O'Brien's stable**, not Aidan O'Brien's. **James J Braddock at 9/1 was the each-way value play we should have flagged** but missed.

This piece covers the **full result + race shape**, and the **Derby ladder implications** -- specifically the Coolmore reshuffle now that Pierre Bonnard is effectively out of the Epsom picture.

## Race shape and how the winner won

This was **a classic Coolmore-family chess match** -- Aidan O'Brien with three runners + Joseph O'Brien + Donnacha O'Brien making it five members of the same training family. **The narrative played out as the longshot-from-the-favourite-yard pattern fired**, but from the JOSEPH O'Brien stable rather than Aidan's.

**The race shape:**

- **Endorsement (Aidan O'Brien) set the pace** through the early stages, with Pierre Bonnard tracking in 2nd
- **Wayne Lordan asked Pierre Bonnard for maximum effort inside the 2-furlong pole** -- the colt began making gains on the leader, and at the furlong pole looked the likely winner
- **James J Braddock came with a sustained late run** under Dylan Browne McMonagle, picking up momentum from the 3-furlong pole onwards
- **The duo went head-to-head inside the final 50 yards** -- Pierre Bonnard had taken the lead from Endorsement, but James J Braddock kept finding more
- **Short-head verdict on the line.**

**Pierre Bonnard's race [Irish Field]:** *"Pierre Bonnard sat in second, tracking his stablemate Endorsement, before Wayne Lordan asked for maximum effort inside the two-furlong marker. Slowly but surely the son of Camelot began to make gains on the leader. But in behind James J Braddock was responding well to Dylan Browne McMonagle's urgings."*

**The 5/6F price** -- Pierre Bonnard went off heavy odds-on favourite based on the reset-from-Ballysax narrative + the Aidan O'Brien public confidence quote. **He ran the better race than at Ballysax but found one too good.**

**Endorsement's third place** is a meaningful Coolmore consolation -- the Ballysax 2nd ran with credit and is now a legitimate Derby second-string at 12/1 to 16/1 ante-post.

## Market and SP trajectory

| Time | Pierre Bonnard | James J Braddock | Endorsement |
|------|----:|----:|----:|
| Antepost (early May) | 4/5 ante-post | 14/1 | 9/2 |
| Race-day morning | 4/6 to evens | 10/1 | 7/2 |
| **SP** | **5/6F** | **9/1** | **7/2** |

**Epsom Derby market response (Betfred, Sunday close):**

- **Pre-race:** Pierre Bonnard 6/1 for the Derby
- **Post-race: 14/1** -- Pierre Bonnard's Derby supplement looks unlikely now
- **Benvenuto Cellini (Chester Vase winner) holds at 9/4F** for the Derby
- **Christmas Day (Dante runner Thu 14 May) holds at 10/1**
- **James J Braddock entered at 33/1** for the Derby -- supplement likely if Joseph O'Brien decides to step him up to 1m4f

**The Coolmore Derby ladder is now:**

1. **Benvenuto Cellini (A O'Brien)** -- 9/4F Derby, the firmly-established lead
2. **Christmas Day (A O'Brien, Dante Thu 14 May)** -- 10/1, the next test
3. **Hawk Mountain (A O'Brien, Dante)** -- 14/1
4. **Pierre Bonnard (A O'Brien)** -- 14/1, supplement unlikely
5. **James J Braddock (J O'Brien)** -- 33/1, supplement-decision pending Joseph's call

## Implications for the Epsom Derby (Saturday 6 June)

### Coolmore's Derby ladder simplifies (and tightens around Benvenuto Cellini)

The 2026 Coolmore Derby ladder is now **cleaner than it was on Sunday morning**:

| Position | Horse | Source race | Status |
|----------|-------|-------------|--------|
| 1 (lead) | **Benvenuto Cellini** | [Chester Vase 4¼ L winner](/racing-news/chester-vase-2026-result/) | **9/4F Derby** -- firmly established lead |
| 2 | **Christmas Day** | [Dante Stakes Thu 14 May](/racing-news/dante-stakes-2026-preview/) | 10/1 -- the next test |
| 3 | **Hawk Mountain** | Dante Stakes (likely) | 14/1 |
| 4 | Pierre Bonnard | Beaten twice at Leopardstown | 14/1 -- supplement unlikely |
| 5 | Endorsement | Ballysax 2nd + Derby Trial 3rd | 16/1 -- second-string |
| Wild-card | James J Braddock | **Leopardstown Derby Trial winner today** | 33/1 -- supplement TBD by Joseph O'Brien |

**Aidan O'Brien's 4-in-a-row Derby bid** (Auguste Rodin 2023 → City Of Troy 2024 → Lambourn 2025 → Benvenuto Cellini 2026?) is now **firmer than ever**. With Pierre Bonnard effectively out of the picture, Coolmore's named lead is Benvenuto Cellini at 9/4F -- the most market-faithful Coolmore Derby pick since City Of Troy in 2024.

### The Pierre Bonnard story is essentially over

The colt was Coolmore's 2025 Group 1 Critérium International winner at Saint-Cloud -- the form line that flagged him as the natural Coolmore Derby lead going into the spring. **Two defeats as odds-on favourite in consecutive runs** (Ballysax 6th, Derby Trial 2nd) is a structural drop in stock that the bookmakers have correctly priced:

- **Pre-Ballysax (early April):** 2/1 ante-post Derby favourite
- **Post-Ballysax (mid-April):** drifted to 6/1 to 12/1
- **Post-Derby Trial (today):** 14/1+ with most major firms; **realistically no longer a Derby contender** unless Coolmore supplements at the last minute

**Aidan O'Brien's pre-race quote** -- *"Don't lose faith in Pierre yet"* -- was the textbook public-confidence boost from a yard preserving optionality. The second defeat has now eliminated that optionality.

### The James J Braddock angle

**Joseph O'Brien's 9/1 winner is the year's most interesting Derby longshot.** Pattern-match: Joseph won the [Chester Cup 2026](/racing-news/chester-cup-2026-result/) at Chester from a longshot-from-the-favourite-yard angle (A Piece Of Heaven at 7/1) just last week. He's now winning at the Derby-trial level too.

**The Derby supplement decision** is the open question. **Joseph O'Brien on the Derby [post-race]:** *"The Derby looks a relatively open race. This guy is one of the contenders now, having won a trial."* That's a strong signal he'll consider it.

**At 33/1 Derby ante-post**, James J Braddock is the value pick of the morning -- short head over Pierre Bonnard on his trial doesn't tell you he wins the Derby, but it doesn't disqualify him either. **Each-way at 33/1 (1/4 odds at 4 places at Bet365 / Coral)** is the structural longshot play.

### Dante Stakes (Thursday 14 May) implications

**The Dante just got bigger.** With Pierre Bonnard out of the Derby picture, **the Dante is now the only remaining Derby trial that can produce a Derby winner** before Epsom on 6 June. The named Coolmore lead is [Christmas Day at 3/1](/racing-news/dante-stakes-2026-preview/) -- and the 5/5 trends profile from our 5-day pre-Dante read.

**If Christmas Day wins the Dante on Thursday**, his Derby price compresses to 5/1 to 13/2, and the 2026 Derby market has just two horses with credible win-only cases: Benvenuto Cellini and Christmas Day.

### What to watch this week

- **Tuesday 12 May:** 48-hour declarations for Wednesday Dante Festival Day 1 (Musidora + Minster)
- **Wednesday 13 May:** Musidora Day -- the year's most-anticipated Oaks trial
- **Thursday 14 May:** Dante Stakes Day -- the year's biggest Derby trial
- **Friday 15 May:** Yorkshire Cup Day -- Royal Ascot Gold Cup pipeline
- **Saturday 16 May:** [Lockinge Stakes at Newbury](/racing-news/lockinge-stakes-2026-preview/) -- first British G1 of the older horses' campaign

## Responsible note

This piece is a transparent application of the trends-scorecard format to the Leopardstown Derby Trial result. **Our pre-race scorecard had Pierre Bonnard at 5/5 trends as the format-cleanest pick at Evens.** The race won. **The format identified the right yard but priced the wrong stable companion** -- a pattern we've now seen at Chester Cup (A Piece Of Heaven longshot won) and Leopardstown Derby Trial (James J Braddock longshot won) within seven days. The format reads will be refined accordingly. Bet only money you can afford to lose, set limits, [BeGambleAware.org](https://www.begambleaware.org).
