Yuri Mansur, The Man with the Yellow Hat, added a new five star feather to his colorful cap on Saturday.

And it’s a Brazilian-bred mare making his dreams come to fruition.

The CSI5* Longines Grand Prix of Hamburg saw 53 combinations contest Frank Rothenberger’s 1.60m course. Fourteen found a clear path to advance to the jump off.

Among them were world no. 3 Steve Guerdat, fresh off a 5* win in Fountainbleau two weeks prior, world no. 13 Harry Charles and Romeo 88, Olympic eventer Sandra Auffarth on Quirici H and world top 50 riders Philipp Weishaupt (no. 42) on Coby and Emanuele Camilli (no. 49).

Second to return, Guerdat set the time to beat early with a double clear in 44.33 seconds on 11-year-old Westphalian mare Lancelotta. But he left door open. Several combinations posted faster times, but none managed to leave all the jumps in the cups.

Mansur and Miss Blue-Saint Blue Farm, however, closed it. Slicing into the double and galloping to the last, the pair crossed the timers in 42.96 to take over the lead. Auffarth followed with a faster time (41.89) but felled a rail to drop into seventh.

The Longines Grand Prix of Hamburg marks Miss Blue-Saint Blue Farm’s first 5* Grand Prix win and Mansur’s second. His won was the The Longines King George V Gold Cup in 2017 at Hickstead on Babylotte.

“It means a lot to me. This is like a dream come true,” said an elated Mansur.

The Brazilian bred mare (Chacco Blue x VDL Zirocco Blue) has only one year and 16 rounds experience at the 1.60m height (Jumpr Stats).

Miss Blue-Saint Blue Farm made her 1.60m debut at LGCT Miami in April last year. By June, she landed her first podium finishes at the height, taking second in the Longines FEI Jumping Nations Cup of Switzerland and first in the Coupe des Nations BarriEre at La Baule, FRA and the 1.55m Turkish Airlines Prize of Europe at Aachen, GER.

Mansur has showed the mare lightly so far in 2024, jumping just 8 rounds at 1.50m or above. The pair’s Jumpr clear round average across all heights is 69% this year, up from 59% the year prior. They are averaging just 1.3 faults versus 2.4 in 2023.

Mansur is the third highest ranked Brazilian rider on the World Rankings.
