BEVERLY HILLS, Calif. — Rachel Alexandra has won the first matchup between racing's leading ladies, beating out undefeated mare Zenyatta for Horse of the Year.

Voters chose the fabulous filly for the year-end honor at the Eclipse Awards on Monday night at the Beverly Wilshire Hotel. Rachel Alexandra received 130 votes to 99 for Zenyatta.

Now the question is whether Zenyatta will get to avenge the defeat.

Owners Jerry and Ann Moss announced Saturday the mighty mare will run as a 6-year-old, perhaps setting up that long-awaited meeting with Rachel Alexandra. The two glamour girls never raced each other despite capturing the public's imagination with rousing victories over the boys.

Zenyatta won the Eclipse Award as the top older female for the second straight year.
