April 4 (UPI) -- After another eventful weekend of racing, pencil in for the Kentucky Derby the names White Abarrio and Cyberknife, maybe Tiz the Bomb and probably a few others, but scratch the filly contender Secret Oath.

White Abarrio won the Curlin Florida Derby off a two-month layoff and despite missing a workout. Cyberknife put trainer Brad Cox back in the Derby picture with an upset win in the Arkansas Derby.

And Tiz the Bomb won the Jeff Ruby Steaks on the Turfway Park all-weather track to earn a Derby ticket but still is a question mark with options elsewhere on turf.

It was an exciting weekend on the international front, too, with Hong Kong Horse of the Year Golden Sixty back in the winning column, Japan's Horse of the Year, Efforia, going down to defeat for just the second time in his stellar career and Nature Strip perhaps earning a Royal Ascot trip with a victory in Australia.

Country Grammer, Crown Pride both prospects for Kentucky Derby
