Power, ridden by Joseph O’Brien for his father, trainer Aidan O’Brien, came off the rail about a furlong from the finish and finished well enough to capture the Group 1 Irish 2000 Guineas on Saturday at the Curragh.

Frankel and Black Caviar, those towering unbeatens, dominate international racing headlines, but how can there be a more admirable racehorse than Cirrus des Aigles? On Sunday at Longchamp, the best older middle-distance horse in Europe will try to win his third Group 1 in a row, and he’ll be favored to beat seven rivals in the Group 1 Prix d’Ispahan.

Bogeyman, an Argentine-bred 6-year-old who was a Group 1 winner earlier this year, is part of a field of 14 in Friday’s Gran Premio 25 at San Isidro Racecourse in Buenos Aires, Argentina. The race offers an automatic Win and You're In berth to the winner for the Breeders’ Cup Turf at Santa Anita on Nov. 3.

Bogeyman, by Editor’s Note, won the Group 3 ClasicoPorteno over about 1 1/2 miles on turf on April 21. The Gran Premio 25 is run over the same distance. In February, Bogeyman won the Group 1 Gran Premio Miguel Martinez de Hoz, his first win at that level.

Aidan O’Brien will have as many as four runners – including Kentucky Derby last-place finisher Daddy Long Legs – in the Irish 2000 Guineas on Saturday at The Curragh, but the O’Brien quartet doesn’t include the race’s ante-post betting favorite, Parish Hall.

Gold Ship, the winner of the Japanese 2000 Guineas, has a tough act to follow in Sunday’s $3.9 million Japanese Derby at Tokyo Racecourse.

The 2011 winner of the Japanese 2000 Guineas, Orfevre, went on to win the Japanese Derby and the Japanese Triple Crown.

The 2000 Guineas, Japanese Derby, and Japanese St. Leger form the Japanese Triple Crown.

Danedream, the blowout winner of the 2011 Prix de l’Arc de Triomphe, made a winning return to the races on Sunday in Germany, beating nine rivals in the Group 2 Grosser Preis der Badischen Unternehmer at Baden-Baden.

I’ll Have Another is not the only 3-year-old in the world with a chance to win a Triple Crown.

The Japanese filly Gentildonna has won the first two stakes in that country’s lucrative series for 3-year-old fillies. Sunday at Tokyo Racecourse, Gentildonna won the $2.52 million Japanese Oaks by five lengths in stakes-record time.

Gentildonna won the first leg of the filly Triple Crown in the Japanese 1000 Guineas at Hanshin Racecourse on April 8. The third and final race in the series is the Group 1 Shuka Sho over about 1 1/4 miles on turf at Kyoto Racecourse on Oct. 14.

Frankel, the unbeaten European superstar, is expected to make his next start in the Group 1 Queen Anne Stakes at Royal Ascot in England on June 19, trainer Henry Cecil announced on his website on Sunday.

The 4-year-old Frankel won his 2012 debut in Saturday’s Group 1 Lockinge Stakes at Newbury Racecourse in England by five lengths.

The Queen Anne Stakes is the top race for older milers at the Royal Ascot meeting.

Feuerblitz, a German-bred colt by Big Shuffle, won the first stakes of his career in Sunday’s Group 2 Italian Derby at Capannelle Racecourse.

Real Solution, bred and owners by Americans Ken and Sarah Ramsey, could only finish sixth as the favorite in the field of 11, the first loss of his four-race career.

When an elite racehorse suffers any kind of injury, one immediately wonders if he has raced for the last time, a situation doubly true when a horse has never lost. So, when news came that Frankel had rapped the tendon on a foreleg while training in April toward his 2012 debut, it was fair to consider the chance the colt would never start again.

But 4-year-old Frankel has made it back, and from the look of the J.T. Lockinge Stakes on Saturday at Newbury in England, he is just as good as ever.
